QMed_SetImageFrameIndex

QMed_SetImageFrameIndex(imageRef; frameIndex):error
	imageRef	Longint	Reference to the image
	frameIndex	Longint	Frame index
	error	Longint	Error result

Changes the current frame index in the case of multi-frame images.

When working with multi-frame images all image commands commands apply to the "current frame". The current frame is identified by its index. The frame index ranges from 1 to the total number of frames in the image. The default frame index is 1.

The image is specified by imageRef. If imageRef is not a valid image, error qmed_paramErr is returned.

Parameter frameIndex specifies the frame index.

Note: A frame index value of zero (0) is usually equivalent to one (1), unless some importers treat the zero value in a special way.
