| SUColor | Stores a RGBA color with 8 bit channels |
| SUColorOrder | A simple struct with four indices indicating the ordering of color data within 32-bit bitmap images. 32-bit bitmap images have 4 channels per pixel: red, green, blue, and alpha where the alpha channel indicates the transparency of the pixel. SketchUpAPI expects the channels to be in different orders on Windows vs. Mac OS. Bitmap data is exposed in BGRA and RGBA byte orders on Windows and Mac OS, respectively. The color order indices facilitate platform independent code when it is necessary to manipulate image pixel data. The struct's data also applies to 24-bit bitmap images except that such images don't have an alpha channel so the SUColorOrder::alpha_index varaible can be ignored |

Additionally length formatters can be used to translate a formatted length/area/volume string into a value. Accessors and setters are exposed for some of the key formatting properties, facilitating customization of the formater. In cases when users want the formatter to reflect the properties of a model, SUModelGetLengthFormatter should be used to more efficiently extract/copy the relevant properties from the model to the formatter |
