Mattias Gaertner rašė:
The LCL TBitmap has no ScanLine property, because under Delphi its
only purpose is fast direct access and this is not possible under all
LCL platforms.
But there is an alternative, which can be used in most cases.
See lazarus/examples/scanline/.
In file "unit.pas" of that

The LCL TBitmap has no ScanLine property, because under Delphi its
only purpose
Hi Mattias,
which build of Lazarus is this available in? Because on the version I
have, Tbitmaps don't have the scanline property.

intel/32bit: of course.
powerpc, intel/64bit: sometimes.
It depends, what tricks your code use. The only guaranteed platform
independent way are the functions of TCanvas.
Will this Scanline code also work on Mac OS X?

Subj. It tells:
Unit1.pas(80,17) Error: identifier idents no member
"Set_BPP32_B8G8R8_A1_BIO_TTB"
Unit1.pas(80,44) Error: Illegal expression

This function is undocumented in help so it is not obvious how to
replaced it.
And wha
