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