RawImage
« on: January 18, 2016, 10:35:17 am »
HI all:

I want to perform some transformations to a a bitmap.
I createa procedure thar receives two bitmaps (TBITMAP), one is the source and the other the result.

I use RawImage for fast pixel access. I read that is the fastest way.
I read data from source image and write to the destination image.


My problem is this:
The image in destination bitmap doesn't refresh correctly if I don't do a canvas.textout call o save the image to a file.

Any suggestions??

Thanks in avance.
Regards.

You are using Windows, right? If so, I believe the problem is related to this thread, and this bug report mentioned in its last post.
