/****************************************************************************
QuickDraw PICT Import Filter
*****************************************************************************
This file contains the interface for the QuickDraw import filter that reads Mac pictures from disk and/or memory. In addition to the Aldus filter interface, it also supports a parameterized interface for Microsoft applications to control some conversion results.
****************************************************************************/
/*--- Possible Aldus-defined error code returns ---*/
#define NOERR 0 // Conversion succeeded
#define IE_NOT_MY_FILE 5301 // Invalid version (not version 1 or 2 PICT)
// Invalid QD2GDI structure version (greater than 2)
// Ill-formed PICT header record sequence
#define IE_TOO_BIG 5302 // Image extents exceed 32K
#define IE_BAD_FILE_DATA 5309 // Image bounding box is empty
// Attempt to read past end of picture
// Corrupted input file
// Zero-length record
#define IE_IMPORT_ABORT 5310 // Opening of source image failed
// Read failure (network failure, floppy popped)
// Most I/O errors
#define IE_MEM_FULL 5311 // CreateMetaFile() failure
// CloseMetaFile() failure
// Unable to allocate memory (out of memory)
#define IE_MEM_FAIL 5315 // Handle lock failure
#define IE_NOPICTURES 5317 // Empty bounding rectangle or nothing drawn
#define IE_UNSUPP_VERSION 5342 // User-defined abort performed
