38 * Pixmap geometry string interpretation :
39 * Each geometry string contains zero or one scale/position
40 * adjustment and may optionally be followed by a colon and one or more
41 * colon-delimited pixmap operations.
42 * The following table shows the valid geometry strings and their
43 * effects on the background image :
44 *
45 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
46 * W and H are percentages of the terminal window size.
47 * X and Y are also percentages; e.g., +50+50 centers
48 * the image in the window.
49 *
50 * Pixmap Operations : (should be prepended by a colon)
51 * tile Tile image. Scaling/position modifiers above will affect
52 * the tile size and origin.
53 * propscale When scaling, scale proportionally. That is, maintain the
54 * proper aspect ratio for the image. Any portion of the
55 * background not covered by the image is filled with the
56 * current background color.
57 * hscale Scale horizontally, tile vertically ?
58 * vscale Tile horizontally, scale vertically ?
59 * scale Scale both up and down
60 * auto Same as 100x100+50+50
