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 * WxH+X Assumes Y == X
72 * WxH Assumes Y == X == 50 (centers the image)
73 * W+X+Y Assumes H == W
74 * W+X Assumes H == W and Y == X
75 * W Assumes H == W and Y == X == 50
76 *
77 * Adjusting position only :
78 * =+X+Y Set position to X% by Y% (absolute).
79 * =+X Set position to X% by X%.
80 * +X+Y Adjust position horizontally X% and vertically Y%
81 * from current position (relative).
82 * +X Adjust position horizontally X% and vertically X%
83 * from current position.
84 *
85 * Adjusting scale only :
86 * Wx0 Multiply horizontal scaling factor by W%
87 * 0xH Multiply vertical scaling factor by H%
88 * 0x0 No scaling (show image at normal size).
89 *
90 * Pixmap Operations : (should be prepended by a colon)
91 * tile Tile image. Scaling/position modifiers above will affect
92 * the tile size and origin.
93 * propscale When scaling, scale proportionally. That is, maintain the
94 * proper aspect ratio for the image. Any portion of the
95 * background not covered by the image is filled with the
96 * current background color.
97 * hscale Scale horizontally, tile vertically ?
98 * vscale Tile horizontally, scale vertically ?
99 * scale Scale both up and down
100 * auto Same as 100x100+50+50
