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