This patch adds scaling function to the move tool.
When the cursor is over the lower right corner of the layer, it changes.
This is to signify that the layer can be scaled by dragging the mouse.
There is currently no preview of the scaling.
Doing a resize every time the mouse moves leads to unexpected behavior.
Vectorscopes are a standard tool in professional video/film color
grading. *Very* simply, the Vectorscope shows image colors with hue as
the angle and saturation as the radius; brightness for each point in the
scope is determined by the number of "color vectors" at that point. More
specifically, the Vectorscope shows a 2D UV histogram of the image,
where U and V are the chroma ("color") channels of the image.

The histogram is perfectly fine with being drawn at any size, but the
code currently fixes its height to 65. Once the histogram is in a
subclass and several GML things around it change, the fixed height
breaks, so we move the height specification to GML. Additionally, the
container is specified to shrink as much as possible, alleviating a
hard-coded UI size. The user can now change histogram height in GML,
which is a lot more obvious.
Layer::erase_selection used to erase the entire bounding box of the
selection. With the add/subtract merge modes for the selection tool it
is possible to create selections which are not rectangular. This leads
to deleting pixels that were not selected.
This change adjusts the erase behavior to walk the selection rect and
check if a pixel is selected or not before deleting.
Wand Selection tool uses similar logic to the Bucket Tool. Flood filling
and threshold calculations to determine the affected area just in this
case we do not set the pixels of the selected area, instead we use
those pixels to alter the selection mask.
In the future we can probably abstract out the shared flood logic so
both tools can share the code.
Specializing point_position_to_preferred_cell for the
RectangleSelectTool as it selects a new cells with a rounding
behavior instead of a flooring behavior
This is done to allow querying the current active tool inside the
event_with_pan_and_scale_applied and event_adjusted_for_layer
functions without risking a null pointer dereference
This method is used to point a position at the preferred pixel of
the image. Certain tools may want to specify a different preferred
pixel for the same input position.
When cropping to content with a layer not positioned at 0,0 the moved
layers content disappeared and the layers position was not updated
according to the crop offset.
There's probably an easier/more efficient way, but for my testcase this
improves the behavior.
This adds menu item icons for Add Mask, Flatten Image, Fit Image To
View, and Generic 5x5 Convolution.
This modifies the menu item icon for Swap Colors to make the action more
obvious and improve accessibility.
This command finds the smallest non-empty content bounding rect
by looking for the outermost non-transparent pixels in the image,
and then crops the image to that rect.
It's implemented in a pretty naive way, but it's a start. :^)
Instead of having "Flip Horizontally" in both the Image and Layer menus,
we now have "Flip Image Horizontally" and "Flip Layer Horizontally".
This same concept applied to other, similar actions.
The Undo/Redo actions now tell you what kind of action will be
undone/redone. This is achieved by adding an "action text" field to the
ImageUndoCommand and having everyone who calls did_complete_action()
provide this text.
The non-AA outline ellipse was drawn outside the bounding rectangle
unlike all other ellipses. This commit now scales it to match the
size of the other ellipse drawing modes (AA, filled, etc).
The median filter replaces a pixel with the median of all pixels
(usually grey value is used) in a square neighborhood. This is a
standard image processing filter used for denoising, as despite its
simplicity it can e.g. retain edges quite well.
The first implementation is quite inefficient mostly to environmental
constraints. Due to how images are passed to the processing function,
two unnecessary copies happen. And because there's no fast sorting
algorithm for small arrays (insertion sort) yet, quick sort needs to be
used which is quite slow on this scale.
This brings the spacing in line with the rest of the system, and
removes unneeded margins that only bloated the layout and caused edges
to be misaligned.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
This commit removes the file extension in the presented title of images,
and fixes an issue with the previous commit wherein "save as" on an
image would always append ".pp" as an extension, even when the filename
already included this extension.
When creating a new image, a title can be entered. This title was not
used when saving the file however, so naming it was pointless, as the
title used would be whatever was entered during the first save.
This commit makes it so that the default text in the "save as" dialogue
is whatever was entered previously when the image was created.
