Fix transparency in copy() function. Ticket @lighthouse- When using copy() on an image with transparency, the transparency overwrites the background color. See the screenshots to compare against p5. The image is a red splatter with transparent background and the background is green.

  • Issues
On the way to fix this bug, I tried to compare it with how p5 handles this.
To work with p5 code, I cloned it from here with the latest instructions at the bottom of this page.
Then I started to debug it on eclipse, with these instructions.
The result that I'm getting for the pixels from both p5 and pjs are the same. Here is a sample of these results.
I thought it might be something with some charactersitics of pixels in p5 e.g. fillAlpha, calcAlpha,... for which I couldn't find any correspondent in pjs so far.
Those characteristics where changed in pGraphics.java:
several instances of: line 5302:
 calcAlpha = (calcAi != 255); // changed to check for equality to 255


  • Helpful tips
From processingjs.org DOM security will not allow you to load images file:/// URIs. This security can be overridden in Firefox in about:config, by changing security.fileuri.strict_origin_policy to false. Otherwise use
/* @pjs preload="img.jpg"; */
