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
`Get quality C_LONGINT($error) C_LONGINT(gQPixImporter;$quality) $error:=QPx_GetImporterQuality (gQPixImporter;$quality) If ($error#qpx_noErr) `Handle the error End if |
