QPx_GetImporterQuality

QPx_GetImporterQuality(importerRef; drawingQuality):error
	importerRef	Longint	Reference to a graphics importer instance
	drawingQuality	Longint	Drawing quality
	error	Longint	Error result

Returns the current value of the drawing quality property of a graphics importer instance.

The graphics importer instance is specified by importerRef. If importerRef does not refer to an existing graphics importer instance, the qpx_paramErr error code is returned.

Drawing quality is returned as a value in drawingQuality in the range of 0..1024. Some graphics importers ignore this value to improve performance.

QPix defines the following drawing quality constants:

qpx_MinQuality	0	Minimal quality
qpx_LowQuality	256	Low quality
qpx_NormalQuality	512	Normal quality
qpx_HighQuality	768	High quality
qpx_MaxQuality	1023	Maximum quality
qpx_LosslessQuality	1024	Lossless quality

Example

C_LONGINT($error)

C_LONGINT(gQPixImporter;$quality)

$error:=QPx_GetImporterQuality (gQPixImporter;$quality)

If ($error#qpx_noErr)
`Handle the error
