GraphicsExportSetOutputOffsetAndMaxSize

Specifies the output starting offset and maximum size limit.



 
pascal ComponentResult GraphicsExportSetOutputOffsetAndMaxSize ( GraphicsExportComponent ci,

                                         unsigned long offset,

                                         unsigned long maxSize,

                                         Boolean truncateFile);

ci: Specifies the component instance that identifies your connection to the graphics exporter component.
offset: The byte offset of the image data from the beginning of the data reference.
maxSize: A value describing the maximum size limit.
truncateFile: A Boolean value specifying whether to truncate the file.

GraphicsExportGetOutputOffsetAndMaxSize

Returns the output starting offset and maximum size limit.



 
pascal ComponentResult GraphicsExportGetOutputOffsetAndMaxSize ( GraphicsExportComponent ci,

                                         unsigned long *offset,

                                         unsigned long *maxSize,

                                         Boolean *truncateFile);

ci: Specifies the component instance that identifies your connection to the graphics exporter component.
offset: Receives a value describing the byte offset of the image data from the beginning of the data reference.
maxSize: Receives a value describing the maximum size limit.
truncateFile: Receives a Boolean value indicating whether to truncate the file.

If you are not interested in some of these pieces of information, you may pass nil .

ci: Specifies the component instance that identifies your connection to the graphics exporter component.
fileType: The file type for the new image file, such as `JPEG' .
fileCreator: The file creator for the new image file. This parameter may be 0, in which case a default file creator for this file type is used.

GraphicsExportGetOutputFileTypeAndCreator



 
pascal ComponentResult GraphicsExportGetOutputFileTypeAndCreator ( GraphicsExportComponent ci,

                                         OSType *fileType,

                                         OSType *fileCreator);

ci: Specifies the component instance that identifies your connection to the graphics exporter component.
