This object provides functionality for tuning the resolution of writing images to output files depending on the image format. You can set different resolutions for color, gray, and black-and-white images, requesting this object through the ColorPictureResolutionParams, GrayPictureResolutionParams, or BwPictureResolutionParams properties of the PDFPictureCompressionParams object, respectively.
Properties of the PDFExportParams object have priority over the properties of its subobjects. If you change the value of the ResolutionType or Resolution properties of the PDFExportParams object, the values of the corresponding properties of this object will be automatically overwritten. Set the resolution-related properties of the PDFExportParams object first and then use this object to change the resolution for the images of a particular colority.
