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