This commit adds draw_ellipse() and moves the shared code
for circles and ellipses to draw_ellipse_part().
draw_ellipse_part() can draw an entire circle in one call using
8-way symmetry and an ellipse in two calls using 4-way symmetry.
This adds a simple histogram widget that visualizes the rgb-channels
and brightness for a given image. When hovering over the image it will
indicate what brightness level the pixel at the mouse position has.
This is useful, for instance, in games in which you can switch held
items using the scroll wheel. In order to implement this, they
previously would have to either add a hard-coded division by 4, or look
up your mouse settings to adjust correctly.
This commit adds an MouseEvent.wheel_raw_delta_x() and
MouseEvent.wheel_raw_delta_y().
ImageViewer and PixelPaint would crash when the ImageDecoderClient
returns a frame without a bitmap. This can happen with `.ico` files
with an unsupported BPP, for example.
This expands the previously added settings for the asymmetric radii of
th FastBoxBlurFilter to allow the user to specify an angle and the
desired magnitude of blur.
The given values are then calculated forward to corresponding x and y
blur radii.
This way the preview image is not generated on _every_ update_preview()
call but rather only if the last update_preview() was longer than 100ms
ago.
When rapidly moving the Slider for large blur values in the
FastBoxBlurFilter with the Gaussian approximation the usage became
noticeably sliggush because we queued a lot of preview generation just
to throw it away immediately. This patch fixes that.
-Layer now has methods for flip/rotate/crop, which are responsible
for handling the alpha mask.
-Fixed crash when the display image size is out of sync with
the content image size.
-Changed API for setting content and mask image in Layer. Now, both
must be set at the same time, and it can result in an error if
you provide mismatched dimensions.
This is in preparation to support masking of Layers. We now distinguish
between the "display_bitmap" which will be the whole Layer with every
effect applied and the "content_bitmap" which contains the actual
unmodified pixels in the Layer.
This makes it consistent with `ImageViewer`, where `F` was unavailable
for use as a shortcut. A small change, but it's nice having the same
keyboard shortcuts where we can :^)
We often want to zoom and fit the content of the widget into the
visible frame (or some rect within the frame), and it makes sense to
move this functionality into the AbstractZoomPanWidget to minimize
the amount of coordinate math derived classes need to do.
This commit moves the code that implements this functionality from
`PixelPaint::ImageEditor` into `AbstractZoomPanWidget` so that we
can also use it for other applications (such as ImageViewer!)
pledge_domains() that takes only one String argument was specifically
added as a shortcut for pledging a single domain. So, it makes sense to
use singular here.
Now that the GML formatter is both perserving comments and also mostly
agrees to the existing GML style, it can be used to auto-format all the
GML files in the system. This commit does not only contain the scripts
for running the formatting on CI and the pre-commit hook, but also
initially formats all the existing GML files so that the hook is
successfull.
The ImageEditor tracks whether it was loaded from an image
(the alternative being a project file.) If it was loaded from an image
file we redirect save project actions to save as instead.
Now while dragging a new rectangular selection you can cancel it by
hitting Escape. Existing selections are cleared by Escape as well if the
RectangularSelectTool is active.
