Hi all!

I'm porting a project form delphi and I used TBitmap.Scanline in that,
but Lazarus doesn't support it. Could somebody tell me another way for
fast image manipulation?

Hi, Scanline is not supported, you have to use Pixels to access the
image data.
See http://www.lazarus.freepascal.org/index.php?name=PNphpBB2&file=vie
wtopic&t=84 for more details.

TBitmap.ScanLine has been discussed on the mailing list too:

We should implement some fast method of accesing whole images and i
have an ideea on how to do that, i also wanted to copy whole pixels
not just lines even in Delphi and there are some units on the web that
do this, an ideea would be to look at the .tga 2 loader from
delphi3d.net, i also made something similar for a game specific raw
bitmap.
