The
Compression property specifies a compression type when exporting to certain bitmap-image formats. These image formats include export filters that do not provide their own built-in interfaces,such as BMP and TIF. This property is not used with filters that do not support compression or that have a single compression method (such as GIF, PNG, JPG, and CPT). When using the FPX filter, the compression type must be specified through the filter's interface as returned by the
Document.ExportEx or
Document.ExportBitmap methods.
