56 * Pixmap geometry string interpretation :
57 * Each geometry string contains zero or one scale/position
58 * adjustment and may optionally be followed by a colon and one or more
59 * colon-delimited pixmap operations.
60 * The following table shows the valid geometry strings and their
61 * effects on the background image :
62 *
63 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
64 * W and H are percentages of the terminal window size.
65 * X and Y are also percentages; e.g., +50+50 centers
66 * the image in the window.
67 * WxH+X Assumes Y == X
68 * WxH Assumes Y == X == 50 (centers the image)
69 * W+X+Y Assumes H == W
70 * W+X Assumes H == W and Y == X
71 * W Assumes H == W and Y == X == 50
72 *
73 * Adjusting position only :
74 * =+X+Y Set position to X% by Y% (absolute).
75 * =+X Set position to X% by X%.
76 * +X+Y Adjust position horizontally X% and vertically Y%
77 * from current position (relative).
78 * +X Adjust position horizontally X% and vertically X%
79 * from current position.
80 *
81 * Adjusting scale only :
82 * Wx0 Multiply horizontal scaling factor by W%
83 * 0xH Multiply vertical scaling factor by H%
84 * 0x0 No scaling (show image at normal size).
85 *
86 * Pixmap Operations : (should be prepended by a colon)
87 * tile Tile image. Scaling/position modifiers above will affect
88 * the tile size and origin.
89 * propscale When scaling, scale proportionally. That is, maintain the
90 * proper aspect ratio for the image. Any portion of the
91 * background not covered by the image is filled with the
92 * current background color.
93 * hscale Scale horizontally, tile vertically ?
94 * vscale Tile horizontally, scale vertically ?
95 * scale Scale both up and down
96 * auto Same as 100x100+50+50
