60 * Pixmap geometry string interpretation :
61 * Each geometry string contains zero or one scale/position
62 * adjustment and may optionally be followed by a colon and one or more
63 * colon-delimited pixmap operations.
64 * The following table shows the valid geometry strings and their
65 * effects on the background image :
66 *
67 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
68 * W and H are percentages of the terminal window size.
69 * X and Y are also percentages; e.g., +50+50 centers
70 * the image in the window.
71 *
72 * Pixmap Operations : (should be prepended by a colon)
73 * tile Tile image. Scaling/position modifiers above will affect
74 * the tile size and origin.
75 * propscale When scaling, scale proportionally. That is, maintain the
76 * proper aspect ratio for the image. Any portion of the
77 * background not covered by the image is filled with the
78 * current background color.
79 * hscale Scale horizontally, tile vertically ?
80 * vscale Tile horizontally, scale vertically ?
81 * scale Scale both up and down
82 * auto Same as 100x100+50+50
