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