20 Calling load_png with NULL for palette argument was not converting
|
|
|
|
|
paletted images to high/truecolour properly. Fixed. Thanks to
|
|
|

|
Lothar May for pointing it out.
|

13 Changed the method of scaling of palette values from 6 bits
|
|
|
|
|
to 8 bits. Instead of just multiplying by 4, now we use
|
|
|
|
|
_rgb_scale_6[] so that e.g. 0 -> 0, but 63 -> 255.
|
|
|
|

Thanks Nicolas Lemal for the idea.

26 Jon Rafkind suggested to use _getpixel*/_putpixel* in loader to
|
|
|
|
|
speed up loading of large images.
|
|
|
|
|
Split up the code into three files. This prevents the linker pulling
|
|
|
|
|
in unused code, e.g. many people don't need save_png.

28 It turns out that loadpng's origin (example.c from libpng docs) was in
|
|
|
|
|
the public domain, so now loadpng is in the public domain as well.
|
|
|
|

10 Fixed some bugs with load_png(). Now everything in PngSuite loads
|
|
|
|
|
properly, and with correct gamma correction, except for:
|
|
|
|
|
- bKGD chunks (solid background colours) are not respected.
|
2009-11-19 00:34:07 +00:00
|
|
|
I chose this in the past, but I wonder if I should change it?
|
2012-01-05 22:45:03 +00:00
|
|
|
- pHYs chunks (physical dimensions) are not respected.
|
|
|
|
|
(BTW, this was all tested with Valgrind - no errors)

|
|
|
|
2012-01-05 22:45:03 +00:00
|

_png_screen_gamma can now be 0.0 to disable gamma correction, i.e. if
|
|
|
|
|
you don't know the screen gamma, it might be best not to guess.
