|
WORD ID; |
memory ID, user defined value to differentiate between graphics resources of the same type When using EDS_EPMP the following ID values are reserved and used by the Microchip display driver 0 - reserved (do not use) 1 - reserved for base address of EPMP CS1 2 - reserved for base address of EPMP CS2 |
|
DWORD extAddress; |
generic address |
|
FLASH_BYTE * progByteAddress; |
for addresses in program section |
|
FLASH_WORD * progWordAddress; |
for addresses in program section |
|
const char * constAddress; |
for addresses in FLASH |
|
char * ramAddress; |
for addresses in RAM |
|
__eds__ char * edsAddress; |
for addresses in EDS |
|
WORD width; |
width of the image |
|
WORD height; |
height of the image |
|
DWORD param1; |
Parameters used for the GFX_RESOURCE. Depending on the GFX_RESOURCE type definition of param1 can change. For IPU and RLE compressed images, param1 indicates the compressed size of the image. |
|
DWORD param2; |
Parameters used for the GFX_RESOURCE. Depending on the GFX_RESOURCE type definition of param2 can change. For IPU and RLE compressed images, param2 indicates the uncompressed size of the image. |
