Hi there,

In Delphi, accessing to pixels of a Bitmap image via the property of Pixels is very time-consuming. For fast Bitmap editing, reading usually developers use ScanLine property, which returns a pointer to a row of images.
I want to see if there is a similar property in fpc's TBitmap implementation.

Hello *,

As part of 2.0.4 release preparations, we'd like
to bring up to date existing message file
localizations whereever possible. Apparently, our
contacts to original contributors of
localizations to Catalan and Hebrew are broken
now. Are there any volunteers to take over?

BTW, maintainers of other message files are free
to contact me as well (unless they already
received similar message directly from another
member of the FPC core team).

Regards

Tomas

Hi,

I'm the original person that translated the messages to Hebrew, I'm willing to help in the time I have (good to hear that someone actually interested in that :)).

Ido

1: try doing it exactly as you do in delphi
2: if 1 fails file a bug report and mark it as compatibility
