vpv v0.8.2

• add scripting function reload_svgs to clear the svg cache
• fix crash when opening an empty directory as a sequence
• fix compilation with gcc 13

vpv v0.8.1

• fix crash when working with non existing .npy files
• SDL: allow the OS screensaver to trigger
• nix: compile with rust and octave support
• scripting API: add selection_is_shown, gSelectionFrom, gSelectionTo
• scripting API: ensure a tick rate of 10Hz minimum

vpv v0.8.0

New features and improvements

• fuzzy-finder: list and search images from the current sequence by name, opened by pressing g (requires Rust to be setup at compile time)
• improve sequence listing to support s3://, https:// and http:// and zip files (when linked with gdal)
• speed-up sequence listing when reading large folders on remote mounts
• layout: support horizontal custom layouts. For example: vpv l:h,1,3 to have one image on the left, three on the right
• fix: removing the current frame from a sequence now removes the SVG as well
• provide a flake.nix for nix users (with gdal support but not octave or rust yet)

vpv v0.7.1

• fix tiff reader (was causing a crash in rare cases)
• fix cmake for recent releases of SDL2

vpv v0.7.0

Breaking changes

• command line interface:
  replace the filename separator by ::, it was : previously
  example: vpv titi.png::toto.tif
  this was introduced to avoid conflict with protocol:// prefix
• remove GMIC support

New features

• add command line options for player and view objects
  p:frame:<frame>, p:direction:<1|-1>, p:fps:<fps>, p:bouncing:<0|1>, p:looping:<0|1>, p:play
v:zoom:<zoom>, v:center:<x>,<y>, v:svgoffset:<x>,<y>

• when using GDAL support:
  replace s3://, https:// and http:// with their GDAL counterparts
  open .zip as sequences of files
  example combining the two features:
  $ vpv https://www.ssec.wisc.edu/hanis/examples/zipex/michael.zip

• edition: edit images from another index in the collection
  2 the sequence #2, the image at position i (current player index)
  2@5 the sequence #2, the image at position 5 (fixed)
  2@+5 the sequence #2, the image at position i+5
  2@-1 the sequence #2, the image at position i-1
  for example, it can be used to compute temporal differences:
  $ vpv sequence/'*.png' e:'1,1@-1 - fabs'

• add new command line sequence specifier: fromfile:<file>
  each line of <file> is considered as the filename of an image
  example: vpv fromfile:my_list_of_images.txt
  example: vpv fromfile:<(find . -name "*.png")

Improvements

• window:
  add buttons <,> to swap position
  give focus when right-clicking on another window
  highlight tags when hovered
• terminal:
  support text selection and copy from command output
  display stderr and exit code
• layout: support l:8x6 in command line as a shortcut to l:8,8,8,8,8,8
• miniview: use middle click instead of left click to pan view
• green square selection: auto-hide buttons and improve their position
• view: smoother panning with ctrl+

Bug fixes

• png reader: support palette, and 2 and 4 depth bit
• colormap: fix out-of-range when an image has more than 3 channels
• selection: improve rendering of icons
• some fixes for Windows

And many improvements in the codebase, cmake, CI and automated tests!

AppImage and dmg are compiled with GDAL support.

• GDAL: fix loading of complex images
• iio: fix loading of some S1 tiffs

Minor features:

• added shift+q to close the current window

Experimental distribution of appimage binaries for Linux.
MacOS .dmg and Linux .AppImage are precompiled with GDAL support.

vpv v0.6.0

New features:

• add syntax to reuse an object from the cli (vpv im1 nc im2 c:1 im3)
