TIFFs with PSD layers can be saved in either Macintosh or IBM PC format.
IBM PC section labels are reversed and the integers are Little Endian.
We now check for 'MIB8' sections and reverse the necessary values so
that the PSD plug-in functions can handle them.
Certain PSD layers have a flag called clipping set to 1. We were not
handling this flag and had some reports about colors bleeding where
they were not supposed to.
We are going to set GIMP's layer composite_mode to
GIMP_LAYER_COMPOSITE_CLIP_TO_BACKDROP, which is the closest we can get
to PhotoShop's clipping. With this, the colors won't bleed anymore.
This isn't the whole solution since PS apparently stops compositing when
it encounters a layer without clipping set, while GIMP doesn't stop until
it reaches the bottom layer of a group or the image.
This is the first part of a fix for issue #5438.
In certain places in a PSB file we need to read 64-bit
lengths where in a PSD we read a 32-bit length.
To make handling this easier we add a function that
determines if we need to read 4 or 8 bytes and
also handles converting the value from big endian.
in Gimp and Photoshop- "Too many channels in layer: 4907"
To be better able to handle 64 bit offsets we switch to
using GInputStream/GOutputStream and its related
functions instead of using FILE functions like fseek.
In addition we changed several offsets and sizes to
64 bit instead of 32 bit to correctly handle large
image sizes and offsets.
I should probably have split this out in two parts
(the move to GInput/OutputStream, and the
changing to 64 bit variables) but don't feel like
it's worth the trouble at this point.
Streamline the layer-mode mapping code, to reduce duplication.
Add mappings for the following modes: Subtract, Divide, Luma/
luminance darken only (Darker Color), Luma/luminance lighten only
(Lighter Color), and Luminance (Luminosity).
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
