Hi ..

 As you said i tried to read a PNG picture with transparent background but i didnt experience any dark backgroung after reading just check by changing the value of transparency thrash in read PNG file.

RENN,

Probably you monitor is too dark and you should just increase brightness a little bit?

Seriously, when you post such question - its always goot to include an example. In this case: a) image and b) source code snippet - how do you use it?

Look here - I haven't any big problems:

The only small problem that semi-transparency is not supported. You should set threshold (which is 127 by default).

See attached example.

with best regards,

Andrey.

Hello!

I have the same problem. In your example I don't see the half-transparency of the picture, but I want see the same picture as drown in original.

Can anybody help?

Thank you, Eugen

In Andrey's example, they didnt show half-transparency, they showed full transparency.

What is the problem you are having? Their code works fine.

Can't You see the difference between original and imported picture? The blure effect?

I'm programming a CAR PC software and need this functionality. Compare the original Icons and imported to the Front Panel and you will see what I mean.
