bitmap, load and save.
marmin:
Problem!
form1.canvas.brush.color:= clBlack;
BitMap1 := TBitMap.create;
Bitmap1.Loadfromfile('test1.bmp');
bitmap1.canvas.moveto(1,1); bitmap1.canvas.lineto(4,4);
bitmap1.savetofile('test2.bmp');
gives'Acces Violation' run-time error , when writing.
If I omit the pixel edit , things work perfectly.
Could this be anything to do with a DDB? help.
Lightning:
What version of Laz/FPC are you using ?
marmin:
ohoh.. This is a Lazarus bug.
I have just tested the same code in Delphi 6 and it's working fine.
marmin:
ah i d-loaded the latest snapshot and it's fixed ! nice work. cuz I was working on a nice Lazarus Icon Editor-
bitmaps still give strange color conversion results.
- what is the format of an Icon for Linux?
- how can I convert tcolor to tfpcolor?
Nisbo:
mmmm sorry but it doesnt work on my site
Image1.Picture.Bitmap.SaveToFile('TestBitmap.bmp');
TestBitmap.bmp is a black picture :(
