46 * Pixmap geometry string interpretation : 34#define FilterConvolution "convolution"
47 * Each geometry string contains zero or one scale/position 35#endif
48 * adjustment and may optionally be followed by a colon and one or more 36

50 * The following table shows the valid geometry strings and their 38#define RepeatPad True
51 * affects on the background image : 39#endif
52 *
53 * WxH+X+Y Set scaling to W% by H%, and position to X% by Y%.
54 * W and H are percentages of the terminal window size.
55 * X and Y are also percentages; e.g., +50+50 centers
56 * the image in the window.
57 * WxH+X Assumes Y == X
58 * WxH Assumes Y == X == 50 (centers the image)
59 * W+X+Y Assumes H == W
60 * W+X Assumes H == W and Y == X
61 * W Assumes H == W and Y == X == 50
62 *
63 * Adjusting position only :
64 * =+X+Y Set position to X% by Y% (absolute).
65 * =+X Set position to X% by X%.
66 * +X+Y Adjust position horizontally X% and vertically Y%
67 * from current position (relative).
68 * +X Adjust position horizontally X% and vertically X%
69 * from current position.
70 *
71 * Adjusting scale only :
72 * Wx0 Multiply horizontal scaling factor by W%
73 * 0xH Multiply vertical scaling factor by H%
74 * 0x0 No scaling (show image at normal size).
75 *
76 * Pixmap Operations : (should be prepended by a colon)
77 * tile Tile image. Scaling/position modifiers above will affect
78 * the tile size and origin.
79 * propscale When scaling, scale proportionally. That is, maintain the
80 * proper aspect ratio for the image. Any portion of the
81 * background not covered by the image is filled with the
82 * current background color.
83 * hscale Scale horizontally, tile vertically ?
84 * vscale Tile horizontally, scale vertically ?
85 * scale Scale both up and down
86 * auto Same as 100x100+50+50
