pho is entirely keyboard driven, and allows for interactive rotation and taking of notes on each image. It resizes after rotations and will always attempt to show the image as large as possible. The final rotation reached for each image will be remembered and printed when the program exits (for use with a batch image rotation script).

pho can also remember up to ten lists of images (numbered 0-9) which can correspond to anything the user wishes. The image lists will be printed to standard output when pho exits. Use this to keep notes on which images you want to save to the web, which images contain images of your dog, etc.

-d

Debug mode: may print a few debugging messages to standard output.

-v, -h

Print version and usage info, and exit.

-p

"Presentation mode": display in full screen mode with a black background (if the window manager allows it).

-P

Force non-presentation mode.

-n

Replace each image with a new window (slower, but helpful for some broken window managers).

Pho will check the PHO_ARGS environment variable for default flag

settings (e.g. set it to p to use presentation mode by default). Any flags given on the command line will override these settings.

Add the image to the appropriate notes list

f

Toggle in/out of "full screen mode" (or "fit to window"). Images will be scaled up or down to fill the screen in at least one dimension.

F

Toggle in/out of "full size mode". Images will be shown at their native size, even if it's bigger than the screen size. (Hint: Many window managers let you move oversized windows with alt-drag.)

p

Toggle in/out of "presentation mode". If the window manager permits, pho will take up the full screen with the image (if smaller) centered.

+, = Magnify: show the image at twice the current size.

/, - Unmagnify: show the image at half the current size.

q

Quit
