The old method stopped working with the new decoder setup.
The new design features a frame for contrast and rotates
images based on EXIF information.
Closes#89
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
For larger images minimal float errors can add up to having
an image size being minimally larger than the widget.
This leads to fake scrollbars that don't even scroll.
Rounding to physical pixel size fixes this.
Fixes#47
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
GdkPixbuf provides `file_info_future ()` to load the file
info asynchronously, using the gio thread pool. That
means we don't need to spawn a thread ourselves for it.
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.
If only 1/4 of a zoom step zoomed in, assume best-fit.
This helps with floating point precision when zooming in and
out again. It also removes akward other minimal zoom steps.
This change centralizes part of the best-fit detection.
Makes dragging an image out of Loupe work in most cases.
There seems to be an issue with dragging from flatpak to host.
Removing the png from the provider seems to avoid gdk crashes
but not 100% sure that was the cause.
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.
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
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.
