Habe es hinbekommen! Nun habe ich sogar trotzdem satte 50 frames pro Sekunde!!! Wie? Code: protected void paintImage(Graphics g) { Graphics2D g2 = (Graphics2D)g; // [snip] if (interlace){ if (paint){ LaceImageA.getGraphics().drawImage(image, 0,0,image.getWidth(), image.getHeight(), this); paint = false; } else { LaceImageB.getGraphics().drawImage(image, 0,0,image.getWidth(), image.getHeight(), this); paint = true; } } // [snip] if (interlace){ g2.drawImage(LaceImageA,imageRect.x,imageRect.y,imageRect.width,imageRect.height,null); g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.50f)); g2.drawImage(LaceImageB,imageRect.x,imageRect.y,imageRect.width,imageRect.height,null); g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 1.0f)); } else g2.drawImage(image,imageRect.x,imageRect.y,imageRect.width,imageRect.height,null); //.....

Hehehehehe macht ja nichts.... Kann passieren... *ups* Ich dachte, da ich BufferedImage schrieb, sei Java klar.. :upps Hier mal die aktuelle Bildschirmausgabe auf meinem System (3ghz): http://cpc-live.com/deinterlace3.png Wie man sehen kann, ist das Display aber leider bei ca. 15-16 Frames pro Sekunde zu langsam... (Zum Screenshots schiessen reicht das zwar, könnte aber schneller sein)

Huch! Aber hier ist doch das Java-Forum...??!? Wie dem auch sei, Meine Methode sieht bislang so aus: public void setAlpha(int alpha) { for (int x=0;x<image2.getWidth();x++) for (int y=0;y<image2.getHeight();y++) image2.setRGB(x, y, ((( image2.getRGB(x, y)&0x00ffffff) )|alpha<<24)); } // [snip] if (interlace){ if (paint){ setAlpha(128); image.getGraphics().drawImage(image2, 0,0,image.getWidth(), image.getHeight(), this); output.getGraphics().drawImage(image, 0,0,image.getWidth(), image.getHeight(), this); paint = false; } else { image2.getGraphics().drawImage(image, 0,0,image.getWidth(), image.getHeight(), this); paint = true; } image.getGraphics().drawImage(output, 0,0,image.getWidth(), image.getHeight(), this); } Diese Methode ist allerdings relativ langsam. Ich benötige 25 Frames pro Sekunde, was diese Routine nicht immer schafft. Gibt es eine Möglichkeit, dieses zu optimieren?

Achja, fast vergessen: Hier die 2 Ausgangsbilder in einem animierten PNG: (Firefox zur Animationsansicht verwenden, der IE kann das nicht darstellen)

Hallo, wie kann ich ein BufferedImage mit 50%iger Transparenz auf ein zweites zeichnen? Im Photoshop geht das relativ simpel... Problem: Es gibt die Möglichkeit, in meinem emulierten Computer jeweils 2 Bilder mit 25hz anzeigen zu lassen (Interlace) Diese 2 flimmern dann natürlich arg, so dass ich sie zu einem Bild zusammenfassen möchte und dann dieses eine Bild jedes 2te mal updaten lassen möchte. Dafür möchte ich das gepufferte Image halt mit 50% Transparenz auf das aktuelle zeichnen. Erwünschtes Resultat: Gruss, Markus

Seit ich nun weiss, wie diese lästigen Tooltips deaktiviert werden können, geht es nun GEWALTIG weiter in meinem Programm! Erstellt von Camtasia Studio 6 Hier kann man mal schon sehen wie der Desktop bald aussehen wird...

Wer es sich Antun möchte: Mal ein kleines Video der Einstellmöglichkeiten: Erstellt von Camtasia Studio 6 Die Uhr funktioniert noch nicht... Aber bald

Ich habe es nun hinbekommen: UIManager.put("InternalFrame.closeButtonToolTip", ""); UIManager.put("InternalFrame.iconButtonToolTip", ""); UIManager.put("InternalFrame.restoreButtonToolTip", ""); UIManager.put("InternalFrame.maxButtonToolTip", ""); setLook(look); initComponents(); Sorum geht es! Danke! Achja: public void setLook(int look){ try { if (look == 1) UIManager.setLookAndFeel( "com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel" ); if (look == 2) UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); if (look == 3) UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel"); } catch(Exception e ) {e.printStackTrace();} }

Danke für den Versuch, aber der funktioniert leider auch nicht setLook(look); initComponents(); UIManager.put("InternalFrame.closeButtonToolTip", null); UIManager.put("InternalFrame.iconButtonToolTip", null); UIManager.put("InternalFrame.restoreButtonToolTip", null); UIManager.put("InternalFrame.maxButtonToolTip", null); (ob hierbei nun 'null' oder '""' ist kein Unterschied) Trotzdem: Ist auch egal, welchen Style ich verwende, man hat 4 zur Auswahl. Ich möchte kurz erklären, warum ich die Tooltips hier weghaben möchte: Ich filtere die Display Ausgabe bilinear und Tooltips oder auch sogar JComboBox'en verschrotten die bilineare Bildschirmausgabe, so dass ich nur noch 1FP/s erhalte und der Emulator nicht mehr zu bedienen ist. hier mal das Display mit allen möglichen Filtern und Effekten: Ich möchte eine möglichst realistische CRT Monitor Darstellung erreichen. Solange hier also keine JComboBox oder ein Tooltip reinhaut, habe ich das auch bei 50FP/s... Java geht manchmal seltsame Wege :old

Hallo, ich habe folgendes Problem: Ich möchte für mein Programm einen kleinen Desktop basteln, wo ein paar interne Applikationen zu finden sind. So weit, so gut, aber: wenn ich nun über ein Icon in einem Frame fahre, öffnet sich ein Tooltip (Maximieren, Minimieren, Schliessen und so weiter...) Beispiel: Das JInternalframe hier hat schon ToolTipText = null. Wie kann ich das nun auch für die einzelnen Icons machen? MfG Markus

Edit: wer es sich antun möchte: Ich habe ein kleines Video aufgenommen, welches gleichzeitig ein Technik-Test der emulierten Hardware (CRTC, Grafik, Sound) demonstriert: Erstellt von Camtasia Studio 6 Wie man sehen kann wird also die Hardware inzwischen sehr gut emuliert (Nicht wundern wegen der sehr schnellen emulierten Floppy, ich habe den Laufwerks-Turbo aktiv gehabt)

So funzt es: public void askFile(){ try { SwingUtilities.invokeLater(new Runnable() { public void run() { Object[] message = {chooser, "Ok", "Cancel"}; int choice = JOptionPane.showOptionDialog(new Frame(), "Please choose", "Zipped archive", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, message, null); if (choice == 1) cbZipChooser.setSelectedIndex(chooser.getSelectedIndex()); } }); } catch (Exception e) { e.printStackTrace(); } } Was'n blöd :upps:upps:upps:old

Hallo, ich habe ein Problem mit einem eigenen Dialog. Dieser soll sich öffnen, wenn in einer ZIP-Datei mehr als 1 Datei enthalten sind. Dafür habe ich 2 JComboBoxen welche identisch sind. Im Dialog soll nun die eine JComboBox angezeigt werden, und man soll eine Datei daraus auswählen. Daraufhin wird die zweite JComboBox auf den Index der ersten gesetzt. (Zweite hat einen ActionListener, die funktioniert enwandfrei) hier der Code für den Dialog: public void askFile(){ Object[] message = {chooser, "Ok", "Cancel"}; int choice = JOptionPane.showOptionDialog(new JFrame(), "Please choose", "Zipped archive", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, message, null); if (choice == 1) cbZipChooser.setSelectedIndex(chooser.getSelectedIndex()); } In einem anderen Programm von mir funktioniert dieses tadellos. Nur hier nicht... Schliesse ich den Dialog ([X]) erhalte ich folgende Fehlermeldung: Hat hier jemand eine Idee, warum das passiert? Edit: Übrigens erscheint dieser BUG nur wenn die Anwendung gestartet wird. Lade ich im Nachhinein eine ZIP-Datei, ist alles so, wie es sein soll.

Okay, das habe ich auch behoben. Fill wird nun bei Initialisierung 1x erstellt. Ich habe nun ein ganz anderes Problem: Wenn ich "weisse" Bereiche füllen möchte, hängt sich die Routine auf. Ich habe daher "weiss" den Farbwert 0xFEFEFE zugewiesen. Merkt man mit blossem Auge nicht, ist aber dennoch irgendwie doof. Ansonsten funktioniert diese Routine nun einwandfrei.

Wie sieht es denn damit aus? In der einen Klasse rufe ich nur dieses hier auf: public void Fill(int x, int y, int p, int m){ Fill fill = new Fill(); putScreen(); fill.img = img; fill.Fill(x, y, p, m); } Dann habe ich eine zweite Klasse: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ package jemu.system.cpc; import java.awt.Color; import java.awt.image.BufferedImage; /** * * @author Markus */ public class Fill { protected int[] xx = new int[400]; protected int[] yy = new int[400]; protected int z, xStep; protected Color hf, vfl, vfr, fr, fl; protected int fillX, fillY; public BufferedImage img; public int mode; public int pen; public void Fill(int x, int y, int p, int m){ mode = m; pen = p; for (int pf = 0; pf < 400; pf++){ xx[pf] = 0; yy[pf] = 0; } fillX = x; fillY = y; xStep = 1; if (mode == 1) xStep = 2; if (mode == 0) xStep = 4; z = 0; hf = new Color(img.getRGB(fillX, fillY)); if (hf.getRGB() == CPC.getCol(p).getRGB()) return; getCoords(); searchUP(); } protected void getCoords(){ while (fillX <0 || fillX >640-xStep || fillY <0 || fillY>399){ reCalc(); } } public void reCalc(){ z--; if (z>=0){ if (xx[z]>=0) fillX=xx[z]; if (yy[z]>=0) fillY=yy[z]; } } public void searchUP(){ while (z>=0){ while (test(fillX, fillY).getRGB() == hf.getRGB() && fillY < 400) fillY+=2; fillY-=2; fl = new Color (0x44,0x44,0x44); fr = fl; while (fillY>=0 && test(fillX, fillY).getRGB() == hf.getRGB()&& fillX >=0 && fillX<=(640-xStep)){ // look to left vfl = fl; fl = test(fillX-xStep, fillY); if (vfl.getRGB() != hf.getRGB() && fl.getRGB() == hf.getRGB()){ if (fillX >= xStep){ xx[z] = fillX-xStep; yy[z] = fillY; z++;} else{ xx[z] = 0; yy[z] = fillY; z++;} } // look to right vfr = fr; fr = test(fillX+xStep, fillY); if (vfr.getRGB() != hf.getRGB() && fr.getRGB() == hf.getRGB()){ xx[z] = fillX+xStep; yy[z] = fillY; z++; } int cpcY = fillY / 2; int cpcX = fillX / xStep; // plot point CPC.PLOT(cpcX, cpcY, pen, mode); img.getGraphics().setColor(CPC.getCol(pen)); img.getGraphics().drawLine(fillX, fillY, fillX, fillY); fillY-=2; } reCalc(); } } public Color test(int x, int y){ Color result = CPC.getCol(pen); try{ if (x<0) x = 0; if (y<0) y = 0; if (x>=640) x = 639; if (y>=400) y = 399; result = new Color(img.getRGB(x, y));} catch (java.lang.ArrayIndexOutOfBoundsException ek){ System.err.println("Error in FILL! X " + x + " Y " + y);} return result; } } Scheint fehlerfrei zu funktionieren.

Es scheint nun zu funktionieren: protected int[] xx = new int[51]; protected int[] yy = new int[51]; protected int z, xStep; protected Color hf, vfl, vfr, fr, fl; protected int fillX, fillY; public void Fill(int x, int y, int p){ for (int pf = 0; pf < 51; pf++){ xx[pf] = 0; yy[pf] = 0; } fillX = x; fillY = y; xStep = 1; if (mode == 1) xStep = 2; if (mode == 0) xStep = 4; putScreen(); z = 0; hf = new Color(img.getRGB(fillX, fillY)); if (hf.getRGB() == CPC.getCol(p).getRGB()) return; getCoords(); searchUP(); } protected void getCoords(){ while (fillX <0 || fillX >640-xStep || fillY <0 || fillY>399){ reCalc(); } } public void reCalc(){ z--; if (z>=0){ if (xx[z]>=0) fillX=xx[z]; if (yy[z]>=0) fillY=yy[z]; } } public void searchUP(){ while (z>=0){ Graphics page = getGraphics(); page.setColor(CPC.getCol(pen)); while (test(fillX, fillY).getRGB() == hf.getRGB() && fillY < 400) fillY+=2; fillY-=2; fl = new Color (0x44,0x44,0x44); fr = fl; while (fillY>=0 && test(fillX, fillY).getRGB() == hf.getRGB()&& fillX >=0 && fillX<=(640-xStep)){ // look to left vfl = fl; fl = test(fillX-xStep, fillY); if (vfl.getRGB() != hf.getRGB() && fl.getRGB() == hf.getRGB()){ if (fillX >= xStep){ xx[z] = fillX-xStep; yy[z] = fillY; z++;} else{ xx[z] = 0; yy[z] = fillY; z++;} } // look to right vfr = fr; fr = test(fillX+xStep, fillY); if (vfr.getRGB() != hf.getRGB() && fr.getRGB() == hf.getRGB()){ xx[z] = fillX+xStep; yy[z] = fillY; z++; } int cpcY = fillY / 2; int cpcX = fillX / xStep; // plot point CPC.PLOT(cpcX, cpcY, pen, mode); img.getGraphics().setColor(CPC.getCol(pen)); img.getGraphics().drawLine(fillX, fillY, fillX, fillY); page.fillRect(fillX, fillY, xStep, 2); fillY-=2; } reCalc(); } } public Color test(int x, int y){ Color result = CPC.getCol(pen); try{ if (x<0) x = 0; if (y<0) y = 0; if (x>=640) x = 639; if (y>=400) y = 399; result = new Color(img.getRGB(x, y));} catch (java.lang.ArrayIndexOutOfBoundsException ek){ System.err.println("Error in FILL! X " + x + " Y " + y);} return result; } Rekursionen sollten nun auch keine mehr drin sein. Bin dabei, es nun intensiv zu testen.

Ich weiss leider nicht, wie ich die letze Rekursion raus bekomme. Irgendeine Idee? Wäre nett.

Habe es hinbekommen. protected int[] xx = new int[52]; protected int[] yy = new int[52]; protected int z, xStep; protected Color hf, vfl, vfr, fr, fl; protected int fillX, fillY; public void Fill(int x, int y, int p){ for (int pf = 0; pf < 52; pf++){ xx[pf] = 0; yy[pf] = 0; } fillX = x; fillY = y; xStep = 1; if (mode == 1) xStep = 2; if (mode == 0) xStep = 4; putScreen(); z = 0; hf = new Color(img.getRGB(fillX, fillY)); if (hf.getRGB() == CPC.getCol(p).getRGB()) return; getCoords(); } protected void getCoords(){ while (fillX <0 || fillX >640-xStep || fillY <0 || fillY>399){ z--; if (z>=0) fillX=xx[z]; fillY=yy[z]; } searchUP(); } public void searchUP(){ try{ //Graphics page = getGraphics(); //page.setColor(CPC.getCol(pen)); while (test(fillX, fillY).getRGB() == hf.getRGB() && fillY < 400) fillY+=2; fillY-=2; fl = new Color (0x44,0x44,0x44); fr = fl; while (fillY>=0 && test(fillX, fillY).getRGB() == hf.getRGB()&& fillX >=0 && fillX<=(640-xStep)){ // look to left vfl = fl; fl = test(fillX-xStep, fillY); if (vfl.getRGB() != hf.getRGB() && fl.getRGB() == hf.getRGB()){ if (fillX >= xStep){ xx[z] = fillX-xStep; yy[z] = fillY; z++;} else{ xx[z] = 0; yy[z] = fillY; z++;} } // look to right vfr = fr; fr = test(fillX+xStep, fillY); if (vfr.getRGB() != hf.getRGB() && fr.getRGB() == hf.getRGB()){ xx[z] = fillX+xStep; yy[z] = fillY; z++; } int cpcY = fillY / 2; int cpcX = fillX / xStep; // plot point CPC.PLOT(cpcX, cpcY, pen, mode); img.getGraphics().setColor(CPC.getCol(pen)); img.getGraphics().drawLine(fillX, fillY, fillX, fillY); //page.fillRect(fillX, fillY, xStep, 2); fillY-=2; } z--; if (z>=0){ fillX=xx[z]; fillY=yy[z]; getCoords(); } } catch (java.lang.StackOverflowError So){} } public Color test(int x, int y){ Color result = CPC.getCol(pen); try{ if (x<0) x = 0; if (y<0) y = 0; if (x>=640) x = 639; if (y>=400) y = 399; result = new Color(img.getRGB(x, y));} catch (java.lang.ArrayIndexOutOfBoundsException ek){ System.err.println("Error in TEST! X " + x + " Y " + y);} return result; }

Dazu reichen meine Kenntnisse nicht aus, leider. Übrigens: Ich habe mal "test" geprüft. Das Ergebnis ist wirklich sonderbar: (Mein veränderter Code) public Color test(int x, int y){ Color result = CPC.getCol(pen); try{ result = new Color(img.getRGB(x, y));} catch (java.lang.ArrayIndexOutOfBoundsException ek){ System.out.println("img is " + img.getWidth() + "x"+img.getHeight() + " Pixels."); System.out.println("I tested here: " + x + " x " + y + " y"); System.out.println("Java means, this is bad. Why???"); System.out.println(ek.getMessage()); ek.printStackTrace(); System.exit(0);} return result; } Konsolenausgabe: img is 640x400 Pixels. I tested here: 640 x 396 y Java means, this is bad. Why??? Coordinate out of bounds! at sun.awt.image.IntegerInterleavedRaster.getDataElements(IntegerInterleavedRaster.java:202) at java.awt.image.BufferedImage.getRGB(BufferedImage.java:871) at jemu.system.cpc.PaintCanvas.test(PaintCanvas.java:1690)

Hier mal eine kurze GIF Animation, welche zeigt, was passiert: Im zweiten FILL soll der Hintergrund Cyanfarben gefüllt werden. Es werden nicht alle Bereiche gefüllt, sondern es kommt dort zum Fehler, wo er abbricht.

Die ganze Klasse hier posten macht wenig Sinn. Man kann z.b. das CPC.PLOT... wegdenken, es ist hier unwichtig. img ist ein bufferedImage... Edit: Um hier die ganze Klasse posten zu können, müsste ich einige Seiten Code posten. Denn es sind einige Sachen dabei, die wiederum aus anderen Klassen verwendet werden, welche auf einer komplexen Emulation beruhen. Allerdings gebe ich gerne den kompletten Sourcecode raus. Das Image ist übrigens 640x400 Pixel gross.

Hallo zusammen, ich möchte ein altes BASIC Programm in Java verwenden. Dazu habe ich das Programm so gut, wie ich kann, in Java übersetzt, an meine Bedürfnisse angepasst, und verwende es nun. Das Programm ansich tut auch das, was es soll: Nämlich Bereiche füllen. Das Problem hierbei ist nun, dass es mir bei längeren Füllvorgängen einen StackOverFlow error auswirft. Diesen Fehler konnte ich zwar erfolgreich 'catch'en, aber er ist ja immernoch vorhanden. Was nun ist an meinem Code noch falsch? protected int[] x = new int[52]; protected int[] y = new int[52]; protected int z, xStep; protected Color hf, vfl, vfr, fr, fl; protected int fillX, fillY; public Color test(int x, int y){ Color result = CPC.getCol(pen); if (x <= img.getWidth() && y <= img.getHeight() && x>=0 && y>=0) result = new Color(img.getRGB(x, y)); return result; } public void Fill(int x, int y, int p){ fillX = x; fillY = y; xStep = 1; if (mode == 1) xStep = 2; if (mode == 0) xStep = 4; putScreen(); z = 0; hf = new Color(img.getRGB(fillX, fillY)); System.out.println(Util.hex(hf.getRGB())); if (hf.getRGB() == CPC.getCol(p).getRGB()) return; getCoords(); } protected void getCoords(){ if (fillX <0 || fillX >640-xStep || fillY <0 || fillY>399){ getnewCoords(); } else searchUP(); } public void searchUP(){ try{ while (test(fillX, fillY).getRGB() == hf.getRGB() && fillY < 398) fillY+=2; fillY-=2; fl = new Color (0x44,0x44,0x44); fr = fl; fillDown(); } catch (java.lang.StackOverflowError So){System.gc();} } public void fillDown(){ while (fillY>=0 && test(fillX, fillY).getRGB() == hf.getRGB() && fillX<(640-xStep)){ // look to left vfl = fl; fl = test(fillX-xStep, fillY); if (vfl.getRGB() != hf.getRGB() && fl.getRGB() == hf.getRGB()){ x[z] = fillX-xStep; y[z] = fillY; z++; } // look to right vfr = fr; fr = test(fillX+xStep, fillY); if (vfr.getRGB() != hf.getRGB() && fr.getRGB() == hf.getRGB()){ x[z] = fillX+xStep; y[z] = fillY; z++; } int cpcY = fillY / 2; int cpcX = fillX / xStep; // plot point CPC.PLOT(cpcX, cpcY, pen, mode); Graphics page = getGraphics(); img.getGraphics().setColor(CPC.getCol(pen)); page.setColor(CPC.getCol(pen)); img.getGraphics().fillRect(fillX, fillY, xStep, 2); page.fillRect(fillX, fillY, xStep, 2); fillY-=2; } getnewCoords(); } protected void getnewCoords(){ // get new coordinates z--; if (z>=0){ fillX=x[z]; fillY=y[z]; getCoords(); } } Hier übrigens das Original BASIC-Listing: (Schneider CPC Basic 1.0) 10 '*********************************** 20 '*********** FILL - Basic ********** 30 '*********************************** 40 MODE 1:DEFINT a-z:DIM x(50),y(50) 50 '*** Testfigur zeichnen 60 MOVE 100,100:DRAW 150,150,2:DRAW 100,200:DRAW 200,200:DRAW 180,180:DRAW 200,140:DRAW 200,100:DRAW 100,100 70 MOVE 120,120:TAG:PRINT"X Y Z";:TAGOFF 80 '*** Startpunkt und Farbe bestimmen 90 x=160:y=160:f=3:GOSUB 1000:END 1000 '******** FILL-Subroutine ******** 1010 '*** Hintergrundfarbe ermitteln 1020 z=0:hf=TEST(x,y):IF hf=f THEN RETURN 1030 '*** Koord. auf dem Bildschirm ? 1040 IF x<0 OR x>639 OR y<0 OR y>399 THEN 1190 1050 '*** Oberen Rand suchen 1060 WHILE TEST(x,y)=hf AND y<399:y=y+2:WEND 1070 y=y-2:fl=-1:fr=-1 1080 '*** Linie nach unten zeichnen 1090 WHILE y>=0 AND TEST(x,y)=hf 1100 '*** Schaue nach links 1110 vfl=fl:fl=TEST(x-2,y) 1120 IF vfl<>hf AND fl=hf THEN x(z)=x-2:y(z)=y:z=z+1 1130 '*** Schaue nach rechts 1140 vfr=fr:fr=TEST(x+2,y) 1150 IF vfr<>hf AND fr=hf THEN x(z)=x+2:y(z)=y:z=z+1 1160 '*** Punkt setzen 1170 PLOT x,y,f:y=y-2 1180 WEND 1190 '*** Neue Koordinaten holen 1200 z=z-1 1210 IF z>=0 THEN x=x(z):y=y(z):GOTO 1040 1220 '*** Zurueck,falls keine mehr da 1230 RETURN

Das Programm läuft nun zu 98%. Ich habe die Farbreduzierung mit Arrays erstellt, wo eine Farbe mit der nächstmöglichen Farbe verglichen wird. (Ist ja nicht so schwer, bei nur 27 vordefinierten Farben) Der Vorteil des Arrays ist, dass es blitzschnell geht. Maximale Renderdauer eines Bildes liegt bei ca. 2-3 Sekunden, wenn das Bild wirklich gross ist. Normalfall: < 0,5 Sekunden. Hier mal eine GIF-Animation, welche veranschaulicht, wie im Bruchteil von Sekunden das Bild umgewandelt wird, und wie man es dann noch weiterbearbeiten kann: Edit: Übrigens ist das Resultat nach jeder "Aktion" kein neu gerendertes Bild, sondern der direkte Inhalt des Screen-Rams des emulierten Computers. Man sieht das Bild also gleichzeitig im Emulator, wie es entsteht.

Stimmt. Ich habe mir nun einen Wolf gegoogelt. Wer kann mir sagen, wie ich ein neues BufferedImage erzeugen kann? Und zwar brauche ich etwas wie: public BufferedImage convert(BufferedImage input){ BufferedImage output = new BufferedImage(640,400,BufferedImage.TYPE_INT_RGB); // Palette Colours enthält die vorgegebenen Farben int anzahl_der_farben = colours.getLength(); for (int i = 0; i < anzahl_der_farben; i++){ // konvertiere input zu output } return output; } Wobei colours[] die einzelnen Color(RR,GG,BB) enthalten würde, welche verwendet werden dürfen. Genau das ist, was ich hier brauche. Nur wie gesagt: Bei Google hab ich nicht viel hilfreiches gefunden. Auch die JavaDOCs sind leider sehr unglücklich gestaltet. Wäre also super, wenn mir jemand so einen Code zeigen könnte.
