32/* 29/*
33 * These GEOM strings indicate absolute size/position: 30 * Pixmap geometry string interpretation :
34 * @ `WxH+X+Y' 31 * Each geometry string contains zero or one scale/position
35 * @ `WxH+X' -> Y = X 32 * adjustment and may optionally be followed by a colon and one or more
36 * @ `WxH' -> Y = X = 50 33 * colon-delimited pixmap operations.
37 * @ `W+X+Y' -> H = W 34 * The following table shows the valid geometry strings and their
38 * @ `W+X' -> H = W, Y = X 35 * affects on the background image :
39 * @ `W' -> H = W, X = Y = 50
40 * @ `0xH' -> H *= H/100, X = Y = 50 (W unchanged)
41 * @ `Wx0' -> W *= W/100, X = Y = 50 (H unchanged)
42 * @ `=+X+Y' -> (H, W unchanged)
43 * @ `=+X' -> Y = X (H, W unchanged)
44 * 36 *
45 * These GEOM strings adjust position relative to current position: 37 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
46 * @ `+X+Y' 38 * W and H are percentages of the terminal window size.
47 * @ `+X' -> Y = X 39 * X and Y are also percentages; e.g., +50+50 centers
40 * the image in the window.
41 * WxH+X Assumes Y == X
42 * WxH Assumes Y == X == 50 (centers the image)
43 * W+X+Y Assumes H == W
44 * W+X Assumes H == W and Y == X
45 * W Assumes H == W and Y == X == 50
48 * 46 *
49 * And this GEOM string is for querying current scale/position: 47 * Adjusting position only :
50 * @ `?' 48 * =+X+Y Set position to X% by Y% (absolute).
49 * =+X Set position to X% by X%.
50 * +X+Y Adjust position horizontally X% and vertically Y%
51 * from current position (relative).
52 * +X Adjust position horizontally X% and vertically X%
53 * from current position.
54 *
55 * Adjusting scale only :
56 * Wx0 Multiply horizontal scaling factor by W%
57 * 0xH Multiply vertical scaling factor by H%
58 * 0x0 No scaling (show image at normal size).
59 *
60 * Pixmap Operations : (should be prepended by a colon)
61 * tile Tile image. Scaling/position modifiers above will affect
62 * the tile size and origin.
63 * propscale When scaling, scale proportionally. That is, maintain the
64 * proper aspect ratio for the image. Any portion of the
65 * background not covered by the image is filled with the
66 * current background color.
67 * hscale Scale horizontally, tile vertically ?
68 * vscale Tile horizontally, scale vertically ?
69 * scale Scale both up and down
70 * auto Same as 100x100+50+50
