Jurgen: The patch doesn't work for me. Do you have a sample image and mapfile?

I'd like to quickly get this into 4.10.1. What format is the testcase in?

Ah, the one compression extension I did not try... Thanks.

(Note the patch has been applied in both 4.10 and 5.0 it's just that my test 
case doesn't work as expected.)

BTW, there is no sign that this patch made it into CVS head (aka 4.99/5.0).

Perhaps I didn't commit when my test case failed. It is in 4.10 though correct?

Steve - apparently yes.  Someone in IRC was asking about this, which is
why I looked into it.

the patch appears to be in 4.10, but does not resolve the test-case in comment #8

Hi,

For what it's worth, I hit this bug tonight with php mapscript 4.10.2 . hobu pointed me to 5.0 beta2 and a potential patch, but neither worked. If I remove the ANGLE, the pixmap is displayed with correct transparency.

I'll make sure the patch supplied is in place but I recall testing it without success. I'll also check to see if GD 2.34 fixes the problem. Should no by tonite.

Steve, I inadvertently applied this patch when I was putting in a fix for #1962. The changeset was r6566.

comment:16 by hobu, 17 years ago

r6565, rather.

comment:17 by sdlime, 17 years ago

If the patch is in then it's not working. The test case draws the black background for me anyway (GD 2.0.35). Works nicely with AGG however.

Milestone: 5.0 release → 5.2 release

The patch was only working for truecolor images so I applied as it was supplied. I still have no luck with the last test case. Can anyone try a couple of other (e.g. 8-bit images) cases and let me know if it works. Deferring to 5.2 otherwise...

My epiphany with #931 got this one fixed too. r6789
