.Sh MOUSE ACTIONS
.
When viewing an image, by default mouse button 1 pans
.Pq moves the image around
or, when only clicked, moves to the next image
.Pq slideshow mode only ;
button 2 zooms
.Po click and drag left->right to zoom in, right->left to zoom out, click once
to restore zoom to 100%
.Pc ;
and mouse button 3 opens the menu.
.
.Pp
.
CTRL+Button 1 blurs or sharpens the image
.Pq drag left to blur, right to sharpen ;
CTRL+Button 2 rotates the image around the center point.
.
.Pp
.
A note about pan and zoom modes:
In pan mode, if you reach a window border but haven't yet panned to the end of
the image,
.Nm
will warp your cursor to the opposite border so you can continue panning.
.
.Pp
.
When clicking the zoom button and immediately releasing it, the image will be
back at 100% zoom.  When clicking it and moving the mouse while holding the
button down, the zoom will be continued at the previous zoom level.  The zoom
will always happen so that the pixel on which you entered the zoom mode
remains stationary.  So, to enlarge a specific part of an image, click the
zoom button on that part.
.
.
.Sh SIGNALS

.Nm
handles the following signals:
.
.Bl -tag -width indent
.
.It Dv SIGUSR1

.Sh USAGE EXAMPLES
.
Here are some examples of useful option combinations
.
.Bl -tag -width indent
.
.It feh /opt/images
.
Show all images in /opt/images
.
.It feh -r /opt/images
.
Recursively show all images found in /opt/images and subdirectories
.
.It feh -rSfilename /opt/images
.
Same as above, but sort by filename. By default, feh will show files in the
order it finds them on the hard disk, which is usually somewhat random.
.
.It feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images
.
Show 128x128 pixel thumbnails, limit window width to 1024 pixels.
.
.It feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C /usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 /opt/images
.
Same as above, but enable thumbnail caching in ~/.thumbnails and use a smaller
font.
.
.It feh -irFarial/14 -O index.jpg /opt/images
.
Make an index print of /opt/images and all directories below it, using 14 point
Arial to write the image info under each thumbnail.  Save the image as
index.jpg and don't display it, just exit.  Note that this even works without
a running X server
.
.It feh --unloadable -r /opt/images
.
Print all unloadable images in /opt/images, recursively
.
.It feh -w /opt/images/holidays
.
Open each image in /opt/images/holidays in its own window
.
.It feh -FD5 -Sname /opt/images/presentation
.
Show the images in .../presentation, sorted by name, in fullscreen,
automatically change to the next image after 5 seconds
.
.It feh -rSwidth -A Qo mv '%f' ~/images/'%n' Qc /opt/images
.
View all images in /opt/images and below, sorted by width, move an image to
~/image/image_name when enter is pressed
.
.It feh --start-at ./foo.jpg \&.
.
View all images in the current directory, starting with foo.jpg.  All other
images are still in the slideshow and can be viewed normally
.
.It feh --start-at foo.jpg *
.
Same as above
.
.It feh --info \&"exifgrep '\&(Model\&|DateTimeOriginal\&|FNumber\&|ISO\&|Flash\&)' '%f' \&| cut -d \&. -f 4-\&" \&.
.
Show some EXIF information, extracted by exifprobe/exifgrep
.
.El
.
.
.Sh DEPENDENCIES
.
.Nm
requires the
.Cm jpegtran
binary
.Pq usually distributed in Qo libjpeg-progs Qc or similar
for lossless rotation.
.
.Pp
.
To view images from URLs such as http://, you need
.Nm
compiled with libcurl support (enabled by default).  See the
.Sx VERSION
section.
.
.
.Sh BUGS
.
Xinerama support does not really work on Xinerama screens != 0.  Set
.Ev XINERAMA_SCREEN
to the correct number as a workaround.
.
.Pp
.
Thumbnail mode is somewhat inefficient, and because of that not nearly as fast
as it could be.
.
.Pp
.
There are still some zooming issues when using
.Cm --scale-down .
.
