Class Name: RGB Color

Superclass - Color Data

Definition

Contains the actual Red, Green, and Blue data values for a color defined within the Red Green Blue color model. These values are expected to be values between 0.0 and 1.0, inclusive. RGB colors are commonly used by color monitors. The RGB color model is probably the best known color model, and is often visualized as a cube, where the Red, Green, and Blue values define coordinates within the cube.

Example

1. A RGB color for pure black. (Red = 0.0, Green = 0.0, Blue = 0.0)
2. A RGB color for bright red. (Red = 1.0, Green = 0.0, Blue = 0.0)

FAQs

I don't use the RGB color model. How can I get the color values back in the model I use?

If you use the CMY, CMYK, or HSV color models, then you're in luck. If you tell it to, before you retrieve any color objects, the SEDRIS Level 0 Read API will change all of the color objects into RGB Color, CMY Color, or HSV Color objects. And if you need CMYK, ask for CMY, then use the utility functions provided in the SEDRIS Conversions API to convert from CMY to CMYK. To tell the SEDRIS Level 0 Read API which color model you want, after opening the transmittal, before you retrieve any Color Data objects, (or even before you open the transmittal), call the SE_SetColorModel() function, passing in the color model you want to use.

Also, if you ever have color data you want to convert from one color model to another (such as from CMY to RGB), standard utility functions are provided in the SEDRIS Conversions API to carry out these data conversions.
