error | Longint | Error result |
Returns the pixel depth of the image associated with 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.
Pixel depth is returned in pixelDepth. Possible values returned in the pixelDepth parameter are:
Black and white images | 1 |
Color images | 2, 8, 16, 24, 32 |
Grayscale images | 34 (2 bit), 36 (4-bit), 40 (8-bit) |
Example
`Get pixel depth C_LONGINT($error) C_LONGINT($pixelDepth) C_LONGINT(gQPixImporter) $error:=QPx_GetImporterImageDepth (gQPixImporter;$pixelDepth) If ($error#qpx_noErr) `Handle the error End if |
