File browser thumbnails for raw images start with a minimally-processed
images. These images are cached and image adjustments are applied on
top. The black level is "baked-into" the cached image. Therefore, to
reflect the black level adjustments in the thumbnail, one of two options
are required:
1. Cache an image before the black level is applied and process the
black level on top of this image.
2. Recreate the base image with the new black level and cache it.
The first option yields better performance when the user changes the
black level. However, it requires other base adjustments to be applied
every time, such as the camera multipliers. The second option requires
the base image to be recreated every time the black level is changed.
This commit implements the second option. It minimizes code changes, and
therefore possible bugs. It does add a performance penalty when the
black level changes, but the black level adjustment is rarely used.
If an editor is marked as a native command, it is launched using the
older method (native for Windows or Glib otherwise). Non-native commands
are launched with Gio. When reading preferences containing the old style
external editor settings, all commands are marked as native to avoid
breaking them.
Fix bug where the send to editor button shows the wrong editor. The bug
happens when the other editor option is selected while the user edits
the external editors in preferences. When saved, the button shows the
first option is selected instead of the other editor option (the last
entry).
If two images have identical processing parameters, then sending one to
an external editor followed by sending the other one will cause the
first temporary image to be reused. This commit associates the image in
the editor with the "cached" temporary image so that the temporary image
only gets used if the editor image matches.
Caches the name of the most recently generated temporary file used for
exporting to external editors and uses that file if the processing
parameters are identical and the file exists. This can dramatically
improve speed when exporting to multiple different editors.
Replace radio selector in external editor section of preferences with
external editor preferences widget. Replace send-to-GIMP button with
pop-up button for exporting to a selectable application.
Replaces the following deprecated Gtk classes throughout the codebase by their non-deprecated counterparts. Style, HBox, VBox, HPaned, VPaned, HScrollbar, VScrollbar, VSeparator, HSeparator, Stock, Table, VScale and HScale.
Previously, changing to a different scope was done by clicking the scope
type button and cycling through all scopes. This commit decreases the
number of clicks needed to switch between two scopes by adding a radio
selector. The radio buttons can be shown or hidden by pressing the scope
type button. This commit also makes the raw histogram one of the scope
types.
Only perform calculations for the currently shown scope.
Cache the waveform so it can be reused when the scope is resized.
Increase speed of waveform rendering.
