QPx_GetImporterImageDepth

QPx_GetImporterImageDepth(importerRef; pixelDepth):error
	importerRef	Longint	Reference to a graphics importer instance
	pixelDepth	Longint	Pixel depth
	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
