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 |
