This implements the rotate cw/ccw actions in PDFViewer.
Since the rendered pages are stored in a HashMap for caching,
the bitmap is wrapped in a struct with the current rotation.
This way the caching works as expected while zooming, and a new bitmap
is rendered when the page is rotated.
The rotate clockwise/rotate counterclockwise actions can be added to
CommonActions since they are repeated in FontEditor, ImageViewer and
PixelPaint. This keeps the shortcuts and icons consistent across
applications.
The open_outline_action logic was backwards resulting in it
being closed on the first click and opened on the second,
and opposite if document->outline() was true.
There was also a collision with the Ctrl+O shortcut for opening a
document, this changes it to Ctrl+S instead.
This commit also changes the wording to 'Toogle' instead of 'Open/Close'
since the text wasn't updated as expected, and lastly, add a View menu
with the action.
KeyboardMapperWidget's load_map_from_file, load_map_from_system, save,
and save_to_file now all return ErrorOr<void> and no longer handles
alerting the user to potential errors.
main is now responsible for handling errors originating from its calls
to these four functions; it will simply alert the user using the new
method KeyboardMapperWidget::show_error_to_user(Error), which simply
creates a MassageBox displaying the error's string_literal.
This makes the whole program slight more clean feeling :^).
When depressing a key, KeyboardMapperWidget::keydown_event() will now
update only the pressed state of the button associated with the specific
key, instead of also setting the pressed state of the all the buttons to
false.
This makes it possible to highlight multiple pressed keys at once and
makes the code more consistent; the implementation of keyup_event
implied that this was a feature of the program.
Extract the mapping of a name to a character map into its own method.
This only slightly reduces the number of lines, going from 24 to 17
lines, but makes the code somewhat more readable and reduces repetition.
Extract the creation of map-selection radio buttons from create_frame
into the new private method add_map_radio_button(map_name, button_text)
turning 24 lines into 4 + 6 lines. This makes create_frame a little
easier to read. :^)
This is just a slight variation of `/res/icons/16x16/paste.png`, I've
removed the lines on the paper to make it look consistent with the
"New Image" icon, which is an empty piece of paper.
I think this is likely the more common operation and makes more sense
in the toolbar. It calls the 'save as' action internally anyway if there
is no associated file.
Now, when trying to close the application, there is a separate prompt
for each open tab with unsaved changes. Each tab is closed after it is
handled appropriately (assuming the user didn't Cancel), this makes it
so that the message box is always asking about the currently active tab,
allowing the user to see that the image contains.
If at any point the user presses "Cancel", all remaining tabs are kept
open.
Previously MainWidget::request_close() would always put up the
message box asking to save unsaved changes, even if there aren't any.
This patch makes it so that the message box is only shown if the
undo stack is in a modified state.
As noted in the latest hacking video, it doesn't seem to make much
sense to store the title and path in the image itself. These fields
have now been moved to the actual ImageEditor itself.
This allows some nice simplicfications, including getting rid of the
`image_did_change_title` hook of ImageClient (which was just a way to
report back to the editor that the title had changed).
A bloom filter creates fringes around bright areas in the image
mimicking the behavior of real-world cameras.
It gets its own category "Artistic" in the Filter Gallery since its not
one filter per se but a combination of multiple.
The filter works as follows:
- Get only the light areas (above a threshold) of the image
- Blur that image
- Compose onto the original image
The FastBoxBlurFilter has been living in LibGfx for a while and now
it's accessible in PixelPaint. The parameters for the filter are exposed
via the new Filter Gallery.
The wrong conception that done() would stop the program flow right there
lead to the lambda not properly aborting when no filter was selected.
The ExecAborted would be processed and then the nullptr that was
m_selected_filter would be happily dereferenced.
This patch fixes that.
Now, the filters can supply the Filter Gallery with a GUI::Widget such
that the user can interact with the filter. The Filter Gallery in turn
only calls apply() on the filter once it should be run.
This decouples the PixelPaint filters a lot from the ones supported by
LibGfx and paves the way to filters with settings.
For now there still are just the plain LibGfx filters so this change
feels like introducing a lot of boilerplate, but in the future there
will be a lot more to see.
There's only two places where we're using the C99 feature of array
designated initalizers. This feature seemingly wasn't included with
C++20 designated initalizers for classes and structs. The only two
places we were using this feature are suitably old and isolated that
it makes sense to just suppress the warning at the usage sites while
discouraging future array designated intializers in new code.
Enable the warning project-wide. It catches when a non-virtual method
creates an overload set with a virtual method. This might cause
surprising overload resolution depending on how the method is invoked.
In the end this is a nicer API than having separate has_{value,target}()
and having to check those first, and then making another Optional from
the unwrapped value:
completion.has_value() ? completion.value() : Optional<Value> {}
// ^^^^^^^^^^^^^^^^^^
// Implicit creation of non-empty Optional<Value>
This way we need to unwrap the optional ourselves, but can easily pass
it to something else as well.
This is in anticipation of the AST using completions :^)
