This adds proper support for a lot of image formats including SVGs.
It will be the basis for many features to come. The technical core
is an asynchronous renderer that can arrange textures in smaller tiles
which might be generated on demand.
Closes#34, #40, #41, #49
Basis for fixing the following issues #7, #27, #36, #43, #68, #71
This also fixes the issue with the buttons triggering
focus changes when the action is deactivated because buttons
know have their own action.
Fixes#44
Issue #38
Use IndexSet to allow direct access by Path and also allow
an arbitrary ordering that was not possible with Vec. Also
add monitoring of file changes in the directory.
Use a custom LpSlidingView instead of AdwCarousel because
Carousel was never designed for this job and suffered of
bugs. LpSlidingView does not support swiping gestures yet
since they currently don't work yet anyways #24.
Use a new algorithm to fill the LpSlidingView that is
stateless and covers all potential changes in the directory.
This not only fixes bugs but would also work with changed
sorting orders.
This also adds build time template XML validation since it
was useful for the refactoring #46.
Closes#9, #11, #30, #33, #42
Tried to make things more stateless and RefCell usage for robust
- Use object properties to control the action enabled/disabled
- Borrow model RefCell for only one line or use .replace()
- Don't pass models around and borrow as short as possible instead
Fixes#20
GTK 4.10 deprecates the old GtkFileChooser* APIs in favor of a
new GtkFileDialog utility. This new utility uses async functions
instead of a `response` signal, so we can make use of Rust's
async/await patterns.
Give LpImage a native with that should feel nice.
When opening a new window with a new image the window size
is determined by LpImage's natural width.
The image size and EXIF data is loaded before the image such
that the window can be shown in the right dimension while
loading the actual image.
Add shortcuts
- F9 Image properties
- F10 Main menu
- Ctrl +/- for zoom
- Ctrl 0 for best fit
- Ctrl [Shift] R for rotate
- Escape to leave fullscrenen
Updated help overlay accordingly.
- Rename to Loupe to avoid confusion during incubation
and potentially allow for release on Flathub
- Replace GNOME as developer since it violates software policy
- Put a more useful copyright statement
- Add me as developer
Allows us to drop the action! macro and usage of the clone! macro
in the application file.
The first occurrence of clone! is now in window.rs, so the comment
explaining it has moved there.
Zoom via
- Scroll event controller
- Zoom gesture
- Overlay buttons
- Fixed zoom level shortcuts (1=100%, 2=200%)
Scrolling via
- Scrolled window
- Drag gesture
Changes
- Implement best-fit via calculating a zoom level
- Gesture for carousel no longer working because of scrolled window
- Split control overlays into two to not steal inputs in area between
Closes#17
Implement a properties sidebar. In order to prevent
the UI from freezing, we use futures to load and cancel
loading file information. We also make use of
`gdk_pixbuf` and `svg_metadata` in order to get the file's
metadata before the file fully loads, meaning there's
little to no delay between changing files and seeing
the metadata for large images.
The properties widget uses expressions and
properties to avoid glue code for setting each label,
allowing us to have a clean separation between UI
and data.
The GFile is more useful for other data. The window can
use expressions to calculate an appropriate title, so
we no longer need to call `set_title()` or connect to
a signal manually.
This commit also adjusts the `uri()` and `print()`
functions to use `active_file()`
Allan Day's latest mockups have the fullscreen icon on the bottom
left of the image. This commit moves the icon there, using a
GtkExpression for the icon name.
Previously we loaded images synchronously and manually
changed `LpImage`. This could cause freezes when loading
large images and SVGs. We also had no proper feedback for
when a corrupted or unsupported image was loaded.
This commit introduces a major rework to how we handle
images and the gallery. It introduces a swipeable gallery
that loads files asynchronously via a new widget: LpImagePage.
LpImagePage owns the file and information related to the file,
and on creation it spawns a future that either loads an error
page when it can't load something (file deleted, corrupted, or
unsupported) or the actual image via LpImage. LpImagePage
now holds the right-click popover and the associated gestures.
The gestures needed to be moved to LpImagePage in order to
rework LpImageView's overlay - instead of having an overlay
child that's a box with a few buttons, we now have the buttons
as individual overlay children. This could cause them
to overlap each other at certain sizes, but it's required
in order to allow input to reach the carousel below.
Right now this comes with a few regressions:
* Occasionally input gets blocked across the applications. It's
hard to tell if this is caused by swipes or right clicking. This
input issue can cause a crash - no Rust backtrace, so a debugger
is needed.
* The "current" page doesn't seem to be properly loaded by the
time `set_image_from_file ()` finishes, so we need to rework
resizing from image dimensions
* We need to re-implement loading different directories and
files within directories
There also seems to be an issue on touchscreens, swiping between
images on a touchscreen causes responsiveness issues not present
when swiping on a touchpad. My guess is that it's related to
the long press gesture.
Calling `xdg-open` is the wrong thing to do, and has
flaky reliability. What we want is to use the portal
directly with the exact behavior we want.
When using the portal we can't just pass the uri -
we need to own a file descriptor.
