Hi,
Thanks to some excellent work from Giulio Berna, the support for BMP images
in the FCL has been greatly improved (and as such should impact Lazarus)
- BMP Reader enhanced to full Microsoft specs:
+ support for 15,16 bit bitmaps.
+ support for strange color masks at 16, 32 bpp
+ rle4 and rle8 decoding
+ top-down stored bitmaps.
+ Palette behaviour changed: use palette at 1,4,8 bits.
+ Support for OnProgress event.
- BMP Writer support:
+ BitsPerPixel property.
+ Writing at all color depths.
+ RLE8 and RLE4 compression.
I have applied his patches, but am not in the possibility to test all
these changes. If there are people out there which use a lot of images,
I would welcome some feedback.
More changes (dithering, quantizing) of images have also been implemented
by Giulio, and will be committed soon.
Kudos to Giulio Berna,
Enjoy,
Michael.
