32 * These GEOM strings indicate absolute size/position: 47 * Pixmap geometry string interpretation :
33 * @ `WxH+X+Y' 48 * Each geometry string contains zero or one scale/position
34 * @ `WxH+X' -> Y = X 49 * adjustment and may optionally be followed by a colon and one or more
35 * @ `WxH' -> Y = X = 50 50 * colon-delimited pixmap operations.
36 * @ `W+X+Y' -> H = W 51 * The following table shows the valid geometry strings and their
37 * @ `W+X' -> H = W, Y = X 52 * affects on the background image :
38 * @ `W' -> H = W, X = Y = 50
39 * @ `0xH' -> H *= H/100, X = Y = 50 (W unchanged)
40 * @ `Wx0' -> W *= W/100, X = Y = 50 (H unchanged)
41 * @ `=+X+Y' -> (H, W unchanged)
42 * @ `=+X' -> Y = X (H, W unchanged)
43 * 53 *
44 * These GEOM strings adjust position relative to current position: 54 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
45 * @ `+X+Y' 55 * W and H are percentages of the terminal window size.
46 * @ `+X' -> Y = X 56 * X and Y are also percentages; e.g., +50+50 centers
57 * the image in the window.
58 * WxH+X Assumes Y == X
59 * WxH Assumes Y == X == 50 (centers the image)
60 * W+X+Y Assumes H == W
61 * W+X Assumes H == W and Y == X
62 * W Assumes H == W and Y == X == 50
47 * 63 *
48 * And this GEOM string is for querying current scale/position: 64 * Adjusting position only :
49 * @ `?' 65 * =+X+Y Set position to X% by Y% (absolute).
66 * =+X Set position to X% by X%.
67 * +X+Y Adjust position horizontally X% and vertically Y%
68 * from current position (relative).
69 * +X Adjust position horizontally X% and vertically X%
70 * from current position.
71 *
72 * Adjusting scale only :
73 * Wx0 Multiply horizontal scaling factor by W%
74 * 0xH Multiply vertical scaling factor by H%
75 * 0x0 No scaling (show image at normal size).
76 *
77 * Pixmap Operations : (should be prepended by a colon)
78 * tile Tile image. Scaling/position modifiers above will affect
79 * the tile size and origin.
80 * propscale When scaling, scale proportionally. That is, maintain the
81 * proper aspect ratio for the image. Any portion of the
82 * background not covered by the image is filled with the
83 * current background color.
84 * hscale Scale horizontally, tile vertically ?
85 * vscale Tile horizontally, scale vertically ?
86 * scale Scale both up and down
87 * auto Same as 100x100+50+50
