wanted: extremely simple image viewer to use in terminal in X

every image viewer i have tried (many of them that google has found) puts extra stuff in the window (like editing features). the one exception is the display command from ImageMagik. display has a serious usability problem. when the image is larger than can be displayed all at once in 1:1 pixel scaling and it displays just part of the image (this much is OK), the arrow buttons just jump by as many pixels as the part being displayed. i want it to scroll and pan one pixel at a time so i can view the part i want.

basically, i want a viewer that is oriented to aspects of viewing including any startup features working as arguments and options on the command line.

support for videos and animated GIFs is a plus. a single button press needs exit to close the image and quit without asking anything, like 'q' does in the display command.
