The following commit will port MIME types to String. Traits<String>
- used in Vector::contains_slow - can't compare String type with char*,
so we need to use StringView instead.
This patch introduces a new function "Layer::editin_mask_bounding_rect"
that is used within the LevelsDialog, Luminosity and Colormasking to
process only the area where a mask was applied. Therefore we can
greatly reduce the amount of processed pixels if only a small portion
of the image was masked.
With this patch the histogram and vectorscope data for the image is
only computed when the widgets are visible to the user and therefore
saves some processing time when this information is not required
to be computed.
This patch adds three new modes to the brush-tool where it is now
possible to use a dodge or burn function with the brush and a soft mode
where the overdraw is reduced so that the stroke looks much softer.
The dodge and burn functions are used to brighten or darken the colors
in the affected area of the brush. The user can decide if the
highlights, midtones or shadows should be prioritized by the brush.
This patch optimizes how the Brush-Tool modifies the pixels. The new
logic generates a "reference brush" with the required size, falloff
and color only once and uses that for the rawing operations. If no
editing mask is used the reference brush is writen via a blit operation
to the content or mask image. This increases the drawing speed and
therefore also allows bigger brush sizes.
This patch allows a bigger brush tool size of 250 pixels and limits the
cursor bitmap to a reasonable size so that its not much bigger than the
image editor size. If the cursor is bigger as the editor it is rended
with a red edge to indicate that the actual cursor is bigger than
displayed. This change mitigates the OOM conditions when the cursor
gets unusual big.
This patch adds the ability to refine a editing mask by a color-range
based on the pixels of the content image. This is useful for image
editing where mask restirction via luminosity might not fit or just
certain color ranges should be edited.
With this change the image modifications of a filter is only applied to
regions of the image where a editing mask is defined. If no editing
mask is defined the filter modifications are applied to the whole
image.
This adds a function where editing masks can be refined by selecting
a luminosity range that is applied to the content image and mapped to
the editing mask. This function allows the editing of image regions
that match only certain luminosity values.
This patch adds a function to make the editing-eask visible while
beeing in mask-mode so that the user can see which parts are covered
by the masks and can therefore be modified by other tools that support
editing masks.
This patch fixes an issue where the preview for an filter was always
based on the content bitmap even if the edit mode was set to Mask.
Now the preview is using the content or mask bitmap based on the
current edit mode and therefore generates the correct preview of
what is going to be changed.
This patch removes a todo where the revert for any changes could be
optimized. Previously every single pixel was copied back from the
reference bitmap to the content bitmap. Now the editors content
bitmap is just replaced with the reference bitmap that is a copy
of the unchanged content bitmap.
This patch adds a new Editing-Mask type to layers. This kind of mask
is used to restrict changes on the content bitmap only to areas where
the mask is drawn. The intensity of a pixel change is controlled by the
alpha-value of the mask.
Furthermore a function to invert and clear masks has been introduced.
When a new mask is created for a layer the edit mode of the layer is
also changed to Mask so that the user can immediately start to draw the
mask.
