50 * adjustment and may optionally be followed by a colon and one or more 36

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