Pilou.... Like this?

download 'Processing' http://processing.org/download/
install it.
a data folder will thus be created. Put your image in it and copy and paste the code also in the data folder, in a file called what? or what?
run processing; load your image

Strike 1: "unexpected token:513"

pilou

If your orginal image has no background area transparent that will works not!

Try with this one I lauch it now so I am sure that it's work
(click on Select all for select all the code)

size(1024,512);

PImage tabou = loadImage("your_image.png");
 int t = 8;
for (int k = 8; k < 513; k = k + t) {

for (int y = 0; y < 513; y = y + k) {
  for (int x = 0; x < 1023; x = x + k*2) {
   image(tabou,x,y,k*2,k) ;
   }
}
filter(INVERT);
t=t+4;
}
image(tabou,0,0);

Must have cheekerboard on background as transparent aera!

Hope this works!
See you soon in four days

brookefox

Ah..., merci. You are right that my image had no transparent areas though it was a png, though I don't know how you could tell.

Hopefully I'll have something to show.

Bon voyage.

brookefox

Still not working though with another with transparent areas. Same error. Please attach your image file so I can try it. Perhaps the png conversion by FastStone is faulty; I'll try another conversion program.

Didn't work with Irfan as the converter, with three different settings.. The checkerboard is how your prog is configured to display transparency; it can be balck or white or some other, I believe. I'll crank up PS for an other go.

The voting is over, Pilou. No luck here.

Here an original image png (zipped) so unzipp it before any process!

Works for me

If that yet don't work for you with this file, we must find another source of problem!

taboure512.zip

Alas, professor...

pilou

Seems very mysterious
We have the same version of Processing 1.5.1

Can you show me the arborescence of folders / files ( I can't see all them on the image above)

Normally you must have just the file "prog" and the folder "data" on the same level
seems they are not on the same "level" from what I can see
Maybe

brookefox

Some little thing I have wrong... Or maybe a big thing.

I tried it with data next to .exe and with data in taboure512 folder. Same result.

pilou

Have you this arborescence of File / Folder ?
You must have the red rectangle with this little arborescence
anywhere : it's an entity ! Can works anywhere !

Here it's mixed with the arborescence of Processing : can be possible but not very clear

If you have not maybe re-read my first post for create the first arborescence!

If you have yet that is some ennuyous because I don't see anything else!

brookefox

I will reread your first post. Other than that, I am not sure what you are saying. The pic you show is my pic, so that yes is my setup. 'Arborescence' I assume means tree (directory, folder) structure.

My OS is Vista 64.

Yes

No !
it's that you must see (I have made a photomontage)
In yours above I don't see the black icon "taboure512.pde" under the "data"

pilou

If I good remember

the first time launch a Processing session
Copy inside the lines above

Save it in a folder anywhere of your choice say "my Processing test" (name of the folder)
with the name that you want say "test" (name of your prog)

Surrely a message eroor because ther is not yet an image inside the data folder created

QUIT
You must obtain a file "test.pde" and a folder "data" both inside "my Processing test" folder
(".pde" is the extension name of a Processing program normally it's given automatically)
(maybe extension 's file ".pde" is not visible following your system regulates )

You must have the image follow

You can now put inside your image inside the "data" folder created
with the same name than inside the prog : say "sketch.png"

(use always PNG format : support of the transparent background)

Inside the prog the "" must be writed around the sketchUp's image!

PImage pilou = loadImage("sketch.png");

Relaunch it by double click on the file name "test.pde" inside your folder

After 3 seconds (more or less following the age of your computer: mine is ten years! )
An artistic image must be created on your screen

Grab it and past it inside your favorite 2D prog

You can modify some numeric parameters inside the prog

You can change of course the name of the image inside the prog
if you input an other image with another name inside the data folder!
(don't change the "pilou" words except you well understand the syntax)

If you don't want the "filter Invert" on your image
Jut put // before

//filter(INVERT);

The image must have always 1024*512 inside the data folder!

Hope this help you

pilou

And sorry it's the second post that you must maybe re-read

brookefox

OK. I did not show what was beside data, only what was in data. It is beside as you advise.

pilou

Hum hum
Last chance
Copy the folder taboure512 on the Desk and run it from the Desk but I doubt

Have you load and run some processing examples ?
does they work ?

pilou

Try to launch my own one!
