GreRestoreXformData

GreRestoreXformData restores a previously saved transform state. The current transform state is overwritten.

This function can be hooked by the presentation driver.


 * Simulation support: This function is simulated by a handling routine in the graphics engine.

Syntax
GreRestoreXformData(hdc, ulSize, pBuffer, pInstance, lFunction);

Parameters

 * hdc (HDC) - input
 * Device context handle.


 * ulSize (ULONG) - input
 * Size in bytes of pBuffer.


 * pBuffer (PBYTE) - input
 * Pointer to stored transform data.


 * pInstance (PVOID) - input
 * Pointer to instance data.


 * lFunction (ULONG) - input
 * High-order WORD=flags; low-order WORD=NGreRestoreXformData.

Return Code

 * fSuccess (BOOL) - returns
 * Return codes.


 * This function returns BOOLEAN (fSuccess).


 * TRUE Successful
 * FALSE Error


 * Possible Errors Detected:  When an error is detected, the handling routine must call WinSetErrorInfo to post the condition. Error codes for conditions that the handling routine is expected to check include:


 * PMERR_BASE_ERROR
 * PMERR_COORDINATE_OVERFLOW
 * PMERR_DEV_FUNC_NOT_INSTALLED
 * PMERR_HDC_BUSY
 * PMERR_INSUFFICIENT_MEMORY
 * PMERR_INV_COORD_SPACE
 * PMERR_INV_HDC
 * PMERR_INV_IN_AREA
 * PMERR_INV_IN_PATH
 * PMERR_INV_LENGTH_OR_COUNT
 * PMERR_INV_PATTERN_REF_PT_ATTR
 * PMERR_INV_PICK_APERTURE_POSN
 * PMERR_PATH_LIMIT_EXCEEDED


 * Refer to the "Error Explanations" section in the Presentation Manager Programming Reference for further explanation.

Declaration

 * 1) define INCL_GRE_XFORMS
 * 2) include
