Hello
I am experiencing problems re: my Processing project running on different platforms, this was created on a PC/Windows and every thing works fine there but I am told that the applet crashes Mac browser. Have been advised this may have something to do with how the code has been written rather than platform incompatibility - Due to the fact that I am not a programming expert but an artist who worked on the ideas side rather than the code it is difficult for me to trouble shoot in order to make the project as accessible as possible
The applet uses directories of images with Processing effects (version Processing-0091)

If anyone can help or suggest advice I will really appreciate it.

The project page and link to code is:

I have tried using the recent version of Processing (As I wanted to convert the piece into a downloadable applic) but it interfers with the alpha there to make sure the images do not become drowned out with colour. It comes up with an error message to do with Java 2d not supporting alpha. When the applet is clicked, instead of bringing up a new directory of images the whole thing freezes & gives the error message. Is there a way to get the same alpha effect in the newer version?

The error messsage is as follows





This line in the code becomes highlighted:

mask(pAlpha);




mask() cannot be used with JAVA2D

ah, i see.. you can't use mask() the way you're using it.. you can't call mask() on the main drawing surface itself when you're using JAVA2D (which is the default mode). if you switch to size(500, 500, P3D) it may work the way you want.

also, there's no need to set variables called WIDTH and HEIGHT at the beginning.. just use size(500, 500) and then use the variables "width" and "height" throughout your program. that way when you hit export, it'll pick up the size you're using and properly write out the html file for you.
