synchronized void de.softpro.doc.SignDocRenderParameters.setResolution	(	double	aResX,
		double	aResY
	)		throws SignDocException

Set the resolution for rendering PDF documents.

The values passed to this function will be ignored for TIFF documents as the resolution is computed automatically from the zoom factor and the document's resolution.

Throws SignDocInvalidArgumentException if the resolution is invalid.

Parameters:

[in]	aResX	Horizontal resolution in DPI.
