Add a debug procedure group, living in 'debug.pdb', which would host
useful debug helper functions. Functions in this group are not part
of the stable API, and may be changed at any point.
All procedures added to 'debug.pdb' should have a 'debug_' prefix,
and use the new std_pdb_debug() macro, which adds the proper "here be
dragons" warning to their description.
Add two debug procedures: gimp-debug-timer-start() and
gimp-debug-timer-end(), which measure elapsed time, a la
GIMP_TIMER_{START,END}, and can be used to profile script-fu
commands.
We don't support subpixel source sampling, so there's no use in
pretending that we do. Demoting everything to int as soon as
possible helps guarantee that these values are at least rounded
properly and in fewer places.
Make sure we always round coordinates down, and not toward zero.
Keep using floats only in the signatures of the relevant PDB
functions.
Otherwise the file won't be included in the tarball (another consequence
is that `make distcheck` will fail) since this binary is not made the
common automake way on purpose.
Partially reverts commit 84439a8748.
The fact that tools/invert-svg was kind of manually compiled was on
purpose. Using the automake syntax with any of the *_PROGRAMS compiles
for the host OS, but this tool is only for compile-time.
This fixes cross-compilation.
As for compute_svg_viewbox, let's not build it for now because its
purpose was to help proper extraction of SVG icons from a single SVG
file. Unfortunately librsvg was not providing acceptable results anyway
so right now all SVG icons are manually exported. We keep the code for
future use when the library will improve.
which unlike HSL Lightness is actually physically meaningful and
also generally speaking much more useful than HSL Lightness.
Change "Lightness" to "Lightness (HSL)" to make it clear that
the "Lightness" in the Colors/Desaturate/Desaturate menu is not the
same as "Lightness" in LAB/LCH.
For completeness add the option to desaturate to "Value (HSV)".
Add links in app/operations/gimpoperationdesaturate.c
to the Wikipedia article with definitions of L/I/V in HSL/HSI/HSV.
... since that's the color space it actually works in.
Keep the legacy "Color (HSV)" mode's name as is, wrong as it is,
since, well, that's what it used to be called...
Merge mode lays the source layer on top of the destination, same as
normal mode, however, it assumes the source and destination are two
parts of an original whole, and are therefore mutually exclusive.
This is useful for blending cut & pasted content without artifacts,
or for replacing erased content in general.
Calculates the dot product of the two input colors, and uses that
as the value for all the output color's components. Basically,
a per-pixel mono mixer.
Useful for custom desaturation, component extraction, and crazier
stuff (bump mapping!)
Include erase mode in the menu for layers and general paint tools.
This makes the eraser tool somewhat unnecessary, but allows for
interesting use cases (e.g., airbrush eraser, etc.)
... and get rid of the dedicated op. This gives us support for all
the blend/composite options for this mode.
Rename COLOR_ERASE to COLOR_ERASE_LEGACY, with perceptual blending/
compositing and immutable everything, and add a new COLOR_ERASE
mode, defaulting to linear blending/compositing, with mutable
everything. Modify affected code.
being exported to libgimp, and having a non-exported value, this is a
horrible mess like with GimpLayerMode, but at least the cruft value
names are deprecated now.
A bitmask, specifying in which contexts a layer mode is applicable.
Can be a combination of:
- LAYER: usable as a layer mode for actual layers.
- GROUP: usable as a layer mode for layer groups. Currently, all
modes that specify LAYER also specify GROUP, and vice versa,
but the planned pass-through mode will be GROUP only.
- PAINT: can be used as a paint mode.
- FADE: can be used for fading.
Add a 'context' field to _GimpLayerModeInfo, and provide context
masks to all the modes.
Use the context mask for validation when setting a layer's mode.
The next commit will use the mask when populating the layer mode
menus.
and to operations/layer-modes/, respectively.
Add gimp_layer_modes_init() which asserts on the correct order of the
GimpLayerModeInfo array, and switch to accessing the array directly in
gimp_layer_mode_info().
Similar to the Photoshop mode of the same name. Assigns
either 0 or 1 to each of the channels, depending on whether the
sum of source and destination channel values is less than, or
greater than (or equals to), one, respectively.
This is equivalent to inverting the source, and using it to perform
per-pixel, per-channel threshold against the destination, which is
useful for various effects.
Largely based on a patch by Ell, with the enum type renamed and
various small changes. Adds another axis of configurability to the
existing layer mode madness, and is WIP too.
C++ won't allow us to use GimpLayerMode in the API where we used to
have GimpLayerModeEffects.
Move GimpLayerModeEffects to libgimpbase/gimpcompatenums.h so it's
not in the API any longer, and instead typedef and define stuff in
libgimp/gimptypes.h, and adapt the compat enum registering code
accordingly.
For operations needing to override default behavior sub-classes should still be
used.
This commit also enables pinligh, vividlight and linearlight blend mode modes
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.
Change GimpHistogram to take a "gboolean linear" parameter and always
honor that parameter, so both kinds of histograms can now be created
for all drawables.
Add a horrible "Linear" toggle to the histogram dockable which always
defaults to the active layer's actual pixel format, but can be
switched at any time. This UI is ugly and needs to change.
On the PDB, default to gamma-corrected if the plug-in is unaware of
higher precision, and to the drawable's native pixel format otherwise.
Other places using histograms (e.g. levels, curves) are unchanged.
so the threshold can now be based on the GimpHistogramChannel enum.
Add a channel menu to the threshold dialog and a channel argument to
the PDB procedure (which is new in 2.10).
If I hadn't forgotten what the "RGB" channel is supposed to do I would
have implemented the RGB mode in GimpOperationThreshold correctly.
Right now I'm just guessing. Anyone?
They used to be 0..255, inherited from the old gimp_histogram() and
gimp_threshold() procedures. This commit deprecates these old
procedures and changes the ranges in the new gimp_drawable_histogram()
and gimp_drawable_threshold() to double with a 0.0..1.0 range.
Add property "color-tag" of type enum GimpColorTag to GimpItem so all
layers, channels and paths can be tagged with a color.
For interoperability, use the color list from Krita which is a
superset of Photoshop's colors.
Features a "Color Tag" submenu in the layers, channels and paths
menus, a row of color radio buttons in the properties dialogs,
undo and PDB API.
As a side effect, some common code is now factores out into
items-actions.[ch] and items-commands.[ch] which adds visible, linked
and lock actions for layers and channels.
Add a GimpFillType argument to GimpItem::resize() and fill type
widgets to the canvas and layer resize dialogs. Fill the new parts of
the drawable according to fill type in gimp_drawable_resize(). Make
sure places that need the old behavior get GIMP_FILL_TRANSPARENT
passed by hardcoding it in the GimpItem::resize() implemetations of
channel, mask, selection etc.
and use gimp_file_new_for_config_path() and _get_config_path() when
dealing with them. We used a weird mix of config paths and plain
(filesystem encoded) paths, waiting to to break on umlauts or
whatever. The code in gimpcolorconfig.c was particularly bad.
Use the newly added clipboard for entire images to copy/paste layers
(we only create single-layer clipboard images, and use only the first
layer of any recieved image, the layers can be arbitrarily complex
though):
- change gimp_edit_copy,cut,paste() to return/take a GimpObject
that can be a GimpImage or GimpBuffer
- cut/copy the whole layer if there is no selection
- always paste layers as new layers, not floating selections
- always paste news layers on top of the active layer, where
we would attach a floating selection
- add enum GimpPasteType { FLOATING, FLOATING_INTO, NEW_LAYER }
- add GimpPasteType parameter to gimp_edit_paste() and handle all
three cases there because there is now a lot of common code
involved
- change all callers accordingly, use only legacy buffer pasting
from the PDB for now
librsvg has too many bugs and is not reliable for vectorial icon
extraction. I keep the code around for when it changes, but right now,
it is dead code.
isntead of the feather parameter, and pass it to
gimp_gegl_apply_border().
Make the necessary changes to the rest of the code to maintain the
current behavior.
Mass parameter alignment changes to gimpchannel.h. Sigh #2...
Tell the developer not to run pdbgen.pl manually, but make.
Describe the destdir environment variable.
Update the /lib directory to the current /libgimp directory.
README_NEW_PDB_PROC: correct spelling.
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.
With gimp_guide_custom_new(), you can create a custom guide with a different
style on canvas (other pattern/color/width). A custom guide won't be saved
and could be used, for instance, for specific GEGL op guiding.
When checked, diagonally neighboring pixels are considered connected
when calculating the affected area.
This commit also adds a corresponding diagonal_neighbors parameter to
gimp_drawable_bucket_fill(), and modifies the callers, other than the
bucket fill tool, to pass FALSE for this parameter, to retain the
current behavior.
Add PDB sample point API similar to how the guide API works. Add core
API similar to the core guide API to make guide and sample point APIs
as similar as possible.
file-procedure.[ch] is gone and its functions moved to
GimpPlugInManager where they belong (the manager keeps around the
lists of load, save and export procedures).
Utility functions from file-utils.[ch] that have nothing to do with
image files moved to core/gimp-utils.[ch].
Allow to set profiles on grayscale images. Change profile validation
to check for image type and profile type. Actually the patch simply
makes some pieces of code less restrictive. Change user-visible
strings in the profile dialogs accordingly. Change PDB docs
accordingly.
Add new PDB procedures gimp-context-get/set-stroke-method and honor
the new setting in gimp-edit-stroke and gimp-edit-stroke-vectors.
Internally, keep a GimpStrokeOptions around in GimpPDBContext to keep
track of the newly added PDB state, and use it for the stroke
operations instead of creating a scratch GimpStrokeOptions.
Blurbs use third person and need a final point.
Some description were wrong or inaccurate. Add also units where
needed (radius in pixels, angle in degrees).
Some returned values have to be freed.
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".
In e61b1f76 things were changed to return string arrays that can be
freed with g_strfreev(), but that returned a one-element array
containing a NULL pointer for zero-length arrays. Fix the code
to return NULL again for zero-length arrays. See bug #751584.
to not return a reference that has to be dropped. Also allow NULL to
be returned if the managed cannot have a profile. If it can have one,
get_color_profile() still always returns a profile (either the
assigned one, or a generated built-in one).
...when a color profile is active
This commit doesn't fix anything, but it prepares the code to do the
right thing:
It passes the actual raw image pixels through the entire color picking
mechanism to the widgets which display colors, particularly
GimpColorFrame.
This is needed for GimpColorFrame's "Pixel" mode (as opposed to its
RGB, HSV etc. modes) which is supposed to show the raw pixel values
from the image.
Before this commit, it was recreating the raw pixel values from the
GimpRGB value it knows, which will become impossible when we correctly
pick color managed GimpRGB values soon.
not only as parasite. This way we avoid having to create the profile
in each call to gimp_image_get_color_profile(). Also keep the built-in
profiles around in gimp_image_get_builtin_color_profile(). Add/remove
refs and unrefs as needed in all users of these functions.
- gimp-image-set-filename PDB wrapper: implement the same there in
a few lines
- xcf-load.c: use gimp_image_set_file() instead, and get rid of the
last use of filename in xcf/ in favor of GFile
it used to be a typedef to gpointer and actually was a cmsHPROFILE.
Change its API to be more "standard", remove the public close()
function. The object caches both the cmsHPROFILE and the data/length
ICC blob, so conversions between the two become obsolete (simply call
get_lcms_profile() or get_icc_profile()).
Adapt everything to the new API, but port it in a naive way for now,
the code doesn't take advantage of the new possibilities yet (like
refcounting).
