Remarks
TGIS_Color is a platform independent color definition used by TatukGIS Developer Kernel. It is defined as little endian ARGB.
Where:
| Symbol | Name | Min | Max | Comments |
|---|---|---|---|---|
| A | Alpha | 0 | 255 | 0 means fully transparent; 255 means solid |
| R | Red | 0 | 255 | |
| G | Green | 0 | 255 | |
| B | Blue | 0 | 255 |
Sample colors:
| Hex color | Comments |
|---|---|
| $00000000 | Black |
| $00FFFFFF | Pure Red |
| $00FF0000 | Pure Red |
| $0000FF00 | Pure Green |
| $000000FF | Pure Blue |
| $FF000000 | Fully transparent; color has no meaning |
| $80000000 | 50% transparent black |

Each platform has defined conversion functions to convert to/from the actual platform-specific color definition. See GisFramework for VCL or FMX.
