+ − 28 *
+ − 29 * AllocFgGC()
+ − 30 * Given a foreground pixel & a font, return an appropriate GC
+ − 31 *
+ − 32 * AllocBackgroundGC()
+ − 33 * Given a widget, return a GC for painting the background color
+ − 34 *
+ − 35 * AllocShadeGC()
+ − 36 * Given foreground, background, a contrast value & be_nice_to_colormap
+ − 37 * flag, return a GC suitable for rendering in an intermediate color,
442
+ − 38 * as determined by contrast. May return a dither pattern or a
398
+ − 39 * solid color, as appropriate.
+ − 40 *
+ − 41 * Contrast 0 = background color, 100 = foreground color. It is legal
+ − 42 * for contrast to be more than 100 or less than 0.
+ − 43 *
+ − 44 * AllocGreyGC()
+ − 45 * Given widget, foreground, font, contrast & be_nice_to_colormap,
+ − 46 * return a shade GC (see above) based on foreground and widget
+ − 47 * background.
+ − 48 *
+ − 49 * AllocTopShadowGC()
+ − 50 * Given widget, contrast & be_nice_to_colormap, return a GC suitable
+ − 51 * for rendering the top shadow.
+ − 52 *
+ − 53 * Contrast 0 = use background pixel. Contrast > 0 = use brighter
+ − 54 * colors.
+ − 55 *
+ − 56 * AllocBotShadowGC()
+ − 57 * Given widget, contrast & be_nice_to_colormap, return a GC suitable
+ − 58 * for rendering the bottom shadow.
+ − 59 *
+ − 60 * Contrast 0 = use background pixel. Contrast > 0 = use darker
+ − 61 * colors.
+ − 62 *
+ − 63 * AllocArmShadowGC()
+ − 64 * Given widget, contrast & be_nice_to_colormap, return a GC suitable
+ − 65 * for rendering the "armed" shadow.
+ − 66 *
+ − 67 * Contrast 0 = use background pixel. Contrast > 0 = use darker
+ − 68 * colors.
+ − 69 *
+ − 70 * AllocShadowPixel()
+ − 71 * Given a widget & scale factor, allocate & return a color darker
+ − 72 * or lighter than the background pixel, as determined by scale.
+ − 73 *
+ − 74 * Scale 100 = use background pixel. Scale > 100 = brighter color,
+ − 75 * Scale < 100 = darker color.
+ − 76 *
+ − 77 * AllocGreyPixel()
+ − 78 * Given two pixel values and scale factor, allocate & return a
+ − 79 * pixel value between them, according to scale.
+ − 80 *
+ − 81 * Scale == 0: background color
+ − 82 * Scale == 100: foreground color
+ − 83 * 0<Scale<100: intermediate color
+ − 84 * Scale > 100: more foreground
+ − 85 * Scale < 0: more background
+ − 86 *
+ − 87 *
+ − 88 * AllocGreyPixelC()
+ − 89 * Given two color values and scale factor, allocate & return a
+ − 90 * pixel value between them, according to scale.
+ − 91 *
+ − 92 * Scale == 0: background color
+ − 93 * Scale == 100: foreground color
+ − 94 * 0<Scale<100: intermediate color
+ − 95 * Scale > 100: more foreground
+ − 96 * Scale < 0: more background
+ − 97 *
+ − 98 * Draw3dBox()
+ − 99 * Given box dimensions, shadow width, top shadow GC & bottom shadow GC,
+ − 100 * draw a 3-d box.
