Constructor & Destructor Documentation

OriginalBitmapRef::OriginalBitmapRef (  BitmapSource *  pSource = NULL,
BaseBitmapFilter *  pImportFilter = NULL
)

Parameters:
pSource,a pointer to a BitmapSource [INPUTS] pImportFilter, pointer to the filter to use to decode the bitmap

Member Function Documentation

BOOL OriginalBitmapRef::GetOriginalSource (  BitmapSource **  pSource = NULL,
BaseBitmapFilter **  ppImportFilter = NULL
) 
 

Gets the original bitmap file buffer associated with this reference.

Author:
Will_Cowling (Xara Group Ltd) <camelotdev@xara.com>
Date:
8/8/96
Parameters:
pSource,ptr to a BitmapSource ptr to update to point at the original [INPUTS] BitmapSource ppFilterName, ptr to a BaseBitmapFilter ptr to update to point at the filter to use to decode the bitmap
If both these inputs are NULL, then the function will simply return whether an original file exists or not.

Parameters:
The input pointers are set if an original file is available, otherwise they [OUTPUTS] are left unchanged.
Returns:
TRUE, if an original file is available, and the pointers were set if non NULL. FALSE, if no orginal files is available.

void OriginalBitmapRef::SetOriginalSource (  BitmapSource *  pSource = NULL,
BaseBitmapFilter *  pImportFilter = NULL
) 
 

Sets the original bitmap file associated with this reference.

Author:

Date:

Parameters:
pFileBuffer,a pointer to a buffer containing the original file. [INPUTS] pImportFilter, pointer to the filter to use to decode the bitmap
Notes: The input file buffer should be CCMalloc'd, and will be CCFree'd when the reference is destroyed, or changed to another buffer.
