#1061 PNG half transparent - example42

[Klaudiusz]

Hi,
First of all, great work, big thanks.

I have problem with PNG files. They are not displayed correctly.
I found out that in your example42 there is the same problem.

There is 3 files:
-1 image with alpha
-2,3 image and alpha channel

Image with alpha should looks like merged 1,2 but it is half transparent.

I am having the same issue. A PNG shows up as half-transparent.

I've used GD, ImageMagick (6.9.0-10), and used no-alpha channels (just a flat file with a mask). All yield the same result.

Same issue here, after updating TCPDF transparent PNG files became 'half-transparent', like opacity has dropped.

After some debugging I found out a '$info = false;' on line 7029 of tcpdf.php, which appeared between version 6.2.6 and 6.2.9. Removing this line seems to fix the issue.

Big thanks!
I was trying to debug, but don't thought about comparing to old version.

See bug #1070 for more details on the issue (indeed, there is a regression).

This should be fixed in TCPDF 6.2.11
