µGFX allows to write applications (eg. GUIs) that are completely portable as the library itself is highly agnostic. To achieve this goal, users should rely on the types exposed by µGFX as much as possible to prevent problems when migration to different systems.
Pre-Processor
For pre-processing related boolean operations (eg. #if MY_FEATURE) use GFXON and GFXOFF accordingly.

gU8 |
Unsigned integer at least 8 bits wide. |
gI16 |
Signed integer at least 16 bits wide. |
gU16 |
Unsigned integer at least 16 bits wide. |
gI32 |
Signed integer at least 32 bits wide. |
gU32 |
Unsigned integer at least 32 bits wide. |
Rendering
