exported exe hangs when trying to save image 4080x2720

in Programming Questions • 3 years ago

I am trying to finish a submission for the writtenimages.net project, but the exported exe application simply hangs when it should save the generated image, yet it works correctly within the processing writing program.

To add to the frustration, it works correctly on one computer but not on another. On my home computer with windows 7 everything works correctly, but on my work computer with windows vista it hangs.

If I switch the renderer to Opengl it works on the vista computer, but when I send the exe to the guys at writtenimages.net they say it doesn't work. It also works correctly on both the win7 and vista computer if I change the image size to be 1/4 the final needed size.

So is there some trick to getting processing exported .exe's to save really large images? I am at the end of my rope and the deadline for the submissions is today.

With images of this size, you have probably a memory issue.
Try changing the memory settings in the Preferences of Processing, assuming it preserve them when generating an exe.

I will try that. I also made a version of the sketch that is very simple and still has the same problem:

static String[] exportFiles;
static public void main(String args[]) { // dont' change this function
if(args.length <=0) {
String os = System.getProperty("os.name").toLowerCase();
if (os.indexOf( "win" ) >= 0) {
exportFiles = new String[] {
"C:\\image01.tif",
}; //<- change path for debug filenames
}
else if (os.indexOf( "mac" ) >= 0) {
exportFiles = new String[] {
"/image01.tif", "/image02.tif"
}; //<- change path for debug filenames
}
}
else {
exportFiles = new String[args.length];
for(int i=0; i<args.length; i++){
exportFiles[i] = args[i];
}
}
PApplet.main(new String[] {
"exeImageSaver_01" //<- PApplet Filename here <- important!!!
}
);
}
void setup(){
size(4080,2720,JAVA2D);
}
void draw(){
for(int in = 0; in < exportFiles.length; in++){
fill(255,0,0);
ellipse(4080/2,2720/2,300,300);
saveFrame(exportFiles[in]);
}
exit();
}

i also had trouble with my written images app under vista. never did get to the bottom of it. oddly it'd work once then fail. re-exporting or rebooting would mean it'd work again, but only once.

got around it by exporting as a mac app and getting a tame mac user to test it for me. it was fine 8)
(although there's a file called something like info,plist which lets you add the jvm option for more memory and it needed that in order to work. specifically:

<dict>
<key>VMOptions</key>
<string>-Xms64m -Xmx256m</string>
...
</dict>
)

(and in linux, my prefered option, i had to add $* to the exported shell script to get it to accept command line parameters)

results, along with others, are on flickr if anyone cares, tagged with "writtenimagesnet"
