PCDINFO

typedef struct pcdinfo 
{ 
   L_INT resolution[6]; 
} PCDINFO, *pPCDINFO;

The PCDINFO structure is updated by the L_GetPCDResolution function, which tests for available resolutions in a specified PCD file.

Member	Description
resolution	An array of integers. The value of each integer can be 0 or 1. The following symbolic constants are defined for use as indexes into the array:
	Constant Used as Index	Meaning
	L_PCD_BASE_OVER_64	[0] Resolution 64 x 96
	L_PCD_BASE_OVER_16	[1] Resolution 128 x 192
	L_PCD_BASE_OVER_4	[2] Resolution 256 x 384
	L_PCD_BASE	[3] Resolution 512 x 768
	L_PCD_4BASE	[4] Resolution 1024 x 1536
	L_PCD_16BASE	[5] Resolution 2048 x 3072

Comments

pPCDINFO is a pointer to a PCDINFO structure. Where the function parameter type is pPCDINFO, you can declare a PCDINFO variable and pass the variable's address in the parameter. Declaring a pPCDINFO variable is necessary only if your program requires a pointer.
