bgc bgc

Background color. Specifies the subtractive color for colorizable textures and decals.

bgc= *color*

color
RGB or gray color value.

Image Rendering’s texture colorization algorithm is straightforward - the component values of bgc= are subtracted from the values of texture pixels; color= is added, and finally the result is clipped to 0,0,0 and 255,255,255.

For typical uses of texture colorization, the value for bgc= might be the most important or dominant color in the texture image. Dynamic Media Image Authoring provides semi-automatic tools which extract reasonable bgc= color values from textures images.

When a texture material is applied to a non-texturable vignette object, bgc= is applied as the foreground color if color= is not specified.
