This operation produces NAN (0 / 0) and division
by zero when a layer component is zero.
Inline CLAMP to make sure it swallows also NAN.
A NAN is mapped to 1 for backward compatibility.
[the 2variate function comp (in[b], layer[b]) is
discontinuous at layer[b] = 0]
Use cmsFLAGS_NOOPTIMIZE only for actual image buffer or single color
transforms, but not for previews or the image display. Makes things a
lot more responsive again.
Rather than just discovering them by chance, a simple grep and some
search and replace are much more efficient! :-)
Cleaning only done on C and automake files.
which encapsulates a cmsHTRANSFORM and does all the pixel format
conversion magic. It has API to create transforms and proofing
transforms, and to convert pixels arrays and GeglBuffers.
Before, each place which has a transform had to keep around the
transform and its input and output Babl formats, and had to implement
lots of stuff itself. Now all that lives in GimpColorTransform,
removing lots of logic from many places, and pretty much removing lcms
from the public API entirely.
This removes including <lcms2.h>, LCMS_LIBS and LCMS_CFLAGS from
almost all directories and potentially allows to replace lcms by
something else.
... layers with alpha channel
add an operation that selectively outputs aux
or source if out/inside the rectangle (x,y,width,height),
independently of the alpha channel and use it
in filters split preview.
mostly copied from gimp:mask-components
We must not dither the alpha channel if it is fully opaque or fully
transparent. 2.8 did the same but the dithering of these values was
apparently consumed be putting the result into 8 bit values.
Add more user friendly description to the PDB op.
Partially keep the technical description for the PDB op and add a
reference to the developer wiki.
Use the new "reference" key for the GEGL op.
Gamma correction refers to correcting how an image is displayed on
various devices. Gamma adjustment is a more general phrase that also
applies to adjusting gamma as a step in image enhancement in a
color-managed workflow.
and remove lots of labels from calls to gimp_prop_foo_new(). Also
had to manually remove some unwanted labels that are now added
automatically, fixes bug #761880.
Use a proper "progress" signal instead of a property "notify" one
to update the on-canvas progress widget.
This way the graph is not invalidated while processing it
This operation assigns to each pixel the minimum of the
maxima of all paths from it to the outside, as if the
input image represents a height map, and the operation
floods it with water.
which registers config classes for operations that don't want their
config objects to be auto-generated. Register all color tools' config
objects. Change gimp_gegl_config_sync_node() to correctly handle ops
that have an object property of the right config object type.
Add GIMP_DESATURATE_LUMINANCE to enum GimpDesaturateMode and rename
GIMP_DESATURATE_LUMINOSITY to GIMP_DESATURATE_LUMA.
Keep GIMP_DESATURATE_LUMINOSITY as deprecated compat value and add it
to the script-fo and pygimp compat constants.
Change GimpOperationDesaturate to process GIMP_DESATURATE_LUMINANCE
with linear "RGBA float".
GIMP's OVERLAY mode was identical to SOFTLIGHT. This commit fixes the
issue and introduces a NEW_OVERLAY mode and enum value.
- change gimp:overlay-mode to be a real (svg-ish) overlay mode
- when compositing, map OVERLAY to gimp:softlight-mode
- when compisiting, map NEW_OVERLAY to gimp:overlay-mode
- bump the XCF version when NEW_OVERLAY is used
- map OVERLAY to SOFTLIGHT when loading and saving XCF
- map OVERLAY to softlight in all PDB setters
- map OVERLAY to softlight when deserializing a GimpContext
- change all paint mode menus to show an entry for NEW_OVERLAY
instead of OVERLAY
- change PSP, PSD and OpenRaster to use NEW_OVERLAY
These changes should (redundantly) make sure that no OVERLAY enum
value is used in the core any longer because it gets mapped to
SOFTLIGHT at all entry points, with the downside of introducing a
setter/getter asymmetry when OVERLAY was set in a PDB api.
Implement GimpConfigInterface::equal() for the brightness-contrast,
colorize, and threshold config objects, to prevent the parent class'
timestamp being compared by the generic default implementation.
