PGraphics.copy().pixels
Aug 23rd, 2005, 4:00pm  
I haven't really dug into the p55 beta yet so I thought I'd give it a go and start rewriting some of my p55 alpha sketches.

Now I used to do something like:
Code:
BGraphics gTmp = new BGraphics(iWdt,iHgt);
// do some drawing into gTmp
// then put the BGraphics into a BImage
BImage eAlp = new BImage(gTmp.copy().pixels,iWdt,iHgt,ALPHA);


In beta this would be:
Code:
PGraphics gTmp = new PGraphics(iWdt,iHgt,null);
gTmp.defaults();
// do some drawing into gTmp
// then put the PGraphics into a PImage
PImage eAlp = new PImage(gTmp.copy().pixels,iWdt,iHgt,ALPHA);


But I get an error on the copy() in that last line. I'm not sure what to do about it. Might it have something to do with this copy bug?: http://processing.org/discourse/yabb_beta/YaBB.cgi?board=SoftwareBugs;action=display;num=1119220575;start=0#0

that bug was fixed in 92 so if you're using 92 and still seeing the problem, then it's not the same.

what was the error? several red lines in the console? the code didn't compile? your machine lit on fire?

i'm not quite sure what you're trying to do with that code.. if you just want a copy of the PGraphics, then use:

PGraphics eAlp = gTmp.copy();

and then set it to alpha using

eAlp.format = ALPHA;

other than that i can't guess what the error would be.

thanks... that'll help
Yeah ... was just trying to copy the pixel data from gTemp.
I just checked... and I'm using 91... now downloading 92.
The download page has 91 as main download and 92 is in the previous releases, is that right?

yeah, 92 didn't receive proper testing before release so it hasn't been made the "official" release yet and probably won't.. i only make a release the default once things seem to be ok, but i think we'll just go straight to 93 instead.
