Hi, as far as i understand about source code, IEProc.blur function doesnt run for 32bit bitmaps. The function neglects the transparency byte and returns 24bit bitmap result.
Is it really so? Am i missing something?
Or do you propose any solution?

Hi Babur
Yes, you should use SynchronizeRGBA to convert from 32bit -> 24bit+Alpha, do your changes and then use SynchronizeRGBA again to convert it back to 32bit:

Hi Nigel, the problem which i couldnt solve is this;
I have a transparent PNG, i need to draw something transparent on this PNG.
Then i need to call IO functions, like BLUR for example.
It can draw and blur, without problem. But i can not retrive a transparent PNG as result anymore.
To tell it as brief: i want to call blur function on a 32bit bitmap indeed, without loosing my original opacity values. It means that i need blur function to work on transparent bitmaps directly.
But as far as i understood, the blur function works on 24bit bitmap.
Do you think that we can find any solution?

Hi
Internally ImageEn uses 24bit bitmaps, optionally with 1 or 8bit alpha channel. In what context are you using 32bit bitmaps?
You can convert between 24bit+Alpha <--> 32bit using:
