'Perspect' perspectiion correction utility

what does this program do?

- display the image file given in cli argument in a window

- let you select 4 coordinates with left mouse button

- you can move an already pinned point by clicking again so then the closes point will be moved over

- remove a pin point by right-clicking nearby

- middle-click redraws the helper quadrangle

KEYS

F1 - perspective correction (distort) and crop, then open resulting image

F2 - crop around on bounding box, then open

F3 - rotate the image so the drawn line segment (pin 2 points down only, not 4) to be horizontal

F4 - rotate the image so the drawn line segment (pin 2 points down only, not 4) to be vertical

Ctrl-S - save as dialog

Ctrl-O - open in gPicView

ESC - close

HINTS

images are not scaled, but displayed at the original size, so

a window manager which supports Alt-dragging and window regions being out of the screen

is recommended to work on large images.

REQUIREMENTS

- gtk-2, pygtk

- imagemagick, convert(1) is called internally
