Tilesaver not working with V. 1.0 redux

in Contributed Library Questions • 2 years ago

Hi I'm trying to use either Marius Watz' Tilesaver or Toxi's Tiler (see older discussion http://processing.org/discourse/yabb2/YaBB.pl?num=1248245155/0) but can get neither to work correctly.

The Tilesaver example in the library produces a large .tga image with no code errors but the image produced is the same image fragment repeated.

Toxi's Tiler program (from the discussion) produces this error

"PImage.save() requires an absolute path. Use createImage(), or pass savePath() to save()"

at line

buffer.save(fileName + "_" + buffer.width + "x" + buffer.height + "." + format);

I've tried a bunch of different things but can't seem to figure either one out. Any help would be great!

I would like to use it with the GLGraphics library which I imagine would work, but maybe I'm wrong.

Thanks!

I think I figured out the problem with toxi's Tiler.

It works if you replace

buffer = new PImage(gfx.width * numTiles, gfx.height * numTiles);

with

PImage buffer2 = new PImage(gfx.width * numTiles, gfx.height * numTiles);
buffer = createImage(buffer2.width, buffer2.height, RGB);

Sadly my TileSaver library has been broking for some time since the introduction of Processing 1.0, something is wrong with how it accesses Processing's internal data.

I apologize for the lack of support, the truth is I've been using Toxi's code for my own project as he is always the better coder...

Ah that fix for toxi's code worked, thanks guess. Although my tiles are all exactly the same- is this supposed to happen?

This code above is the most inefficient "fix" you can possibly think of, since this does allocate 2 (potentially) super large memory blocks unnecessarily... just replace the buffer creation with this line and all will be fine:

buffer = createImage(gfx.width * numTiles, gfx.height * numTiles, RGB);

Btw. This all is actually caused by a bug in the PImage class, since this error message should not be thrown when you pass in an absolute path, but the logic has been commented out. Maybe you could find the time to submit a ticket on Google Code about that...

with this exact code, it seems that exporting as tga renders some odd results at the bottom of the image. Using tif als filetype does seem to work fine. Is this a bug?
