This command is preserved in QPix v3 for backward compatibility reasons. The graphics importer quality has no meaning in QPix v3 and later.
Sets the drawing quality property of a graphics importer instance. This will be used by the importer when drawing the image in a QPix plug-in area or in thumbnails.
The graphics importer instance is specified by importerRef.
The drawingQuality value is 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 |
If drawingQuality is not in the 0...1024 range or importerRef is not an existing graphics importer instance, the qpx_paramErr error code is returned.
Example
`Set quality to maximum C_LONGINT($error) C_LONGINT(gQPixImporter) $error:=QPx_SetImporterQuality (gQPixImporter;qpx_LosslessQuality) If ($error#qpx_noErr) `Handle the error End if |
