feh

feh is an open source, lightweight and fast image viewer powered by the imlib2 library.

What is new in this release:

• Fix feh occasionally becoming unresponsive when asked to terminate via SIGINT/SIGQUIT/SIGTERM
• Fix --keep-zoom-vp issues introduced in 2.27

What is new in version 2.26.2:

• Show correct filelist position in windows opened from thumbnail mode. Note that navigation is still not supported in those windows
• Improve support for key input from stdin
• Do not push menus off the screen when hitting screen limits

What is new in version :

• Fix double-free/OOB-write in E17 IPC. This only affects the background setting options and requires a malicious X11 app to run alongside feh and pretend to be an E17 window manager. (patch by Tobias Stoeckmann)
• Fix image-specific format specifiers not being updated correctly in thumbnail mode window titles
• Fix memory leak when closing images opened from thumbnail mode
• Fix a possible out of bounds read caused by an unterminated string when using --output to save images in long paths. (patch by Tobias Stoeckmann)
• Fix out of bounds read/write when handling empty or broken caption files. (patch by Tobias Stoeckmann)
• Fix memory leak when saving a filelist or image whose target filename already exists. (patch by Tobias Stoeckmann)

What is new in version 2.18.3:

• Fix double-free/OOB-write in E17 IPC. This only affects the background setting options and requires a malicious X11 app to run alongside feh and pretend to be an E17 window manager. (patch by Tobias Stoeckmann)
• Fix image-specific format specifiers not being updated correctly in thumbnail mode window titles
• Fix memory leak when closing images opened from thumbnail mode
• Fix a possible out of bounds read caused by an unterminated string when using --output to save images in long paths. (patch by Tobias Stoeckmann)
• Fix out of bounds read/write when handling empty or broken caption files. (patch by Tobias Stoeckmann)
• Fix memory leak when saving a filelist or image whose target filename already exists. (patch by Tobias Stoeckmann)

What is new in version 2.9.1:

• Set correct window dimensions on any Xinerama screen, not just the first one (active screen is determined by current pointer location).

What is new in version 2.8:

• Do not apply --scale-down to the thumbnail window. It will be applied to windows opened from this, though.
• Patch by Rob Cornish: Respect --image-bg when setting a wallpaper (bg-center and bg-max)
• Add %V (feh process ID) format specifier
• Fix delete not working on last image with --cycle-once
• Treat quick, low-offset drags (1px or 2px move in

What is new in version 2.7:

• Add --min-dim and --max-dim options to only process images with certain dimensions

What is new in version 2.6.3:

• Fix segfault when doing lossless mirror/rotate and jpegexiforient is not present

What is new in version 2.6.2:

• Set EXIF orientation tag to 1 ("0,0 is top left" aka normal) after running jpegtran. Previously, when doing a lossless rotate, the image was rotated but the corresponding EXIF tag not updated, resulting in wrong image display in programs aware of this EXIF tag.
• Fix spelling in feh(1)
• Compile debug builds with -O0

What is new in version 2.6.1:

• Fix freedesktop.org Thumbnail Managing Standard implementation: when running feh on the current working directory, '/path/to/./image.png' was used for thumbnail name generation. Now it is always '/path/to/image.png'
• Show error message if lossless rotate / flip failed on non-JPEG image
• Show error message if -O / -o failed to save image
• Show error message if load failed and magick is disabled (was broken by feh 2.4)

What is new in version 2.6:

• Fixes and additions in EXIF tag support.
• ImageMagick (convert) is now disabled by default; use --magick-timeout to enable it.
• The format specifiers %o (image offset), %r (image rotation), and %z (image zoom) were added.
• The deprecated --menu-style option was removed.
• --reload now accepts non-decimal values and a bug when using --filelist with .txt files was fixed.
• Also, --reload and --slideshow-delay are no longer mutually exclusive.
• When opening HTTP URLs, %f and %F will now return the URL instead of the temporary local filename.

What is new in version 2.4:

• This version has limited support for all file types supported by ImageMagick, using the convert binary to load them (if available).
• The behaviour of --quiet and --verbose was adjusted to the documentation.
• The new %S and %P format specifiers can be used to print the image size / number of pixels in human readable form with a suffix.

What is new in version 2.1:

• This version fixes handling of images with very long names (mostly from HTTP URLs).
• It adds support for tiling window managers by re-applying --scale-down every time the window is resized.
