This property is generally used only for 1-bit images. For 1-bit images, the compression scheme used is G3 compression if the input file is a G3 compressed TIFF image. For all other images, the compression scheme used is G4 compression.

If the image bit level is greater than 1, the PNG compression scheme is used which yields only a small level of compression at a high price in reduced performance. For this reason, CompressInMemory is not recommended for images with bit levels greater than 1.

Generally, this property is used to conserve memory when displaying many ImagXpress objects at the same time (example: a page of thumbnail images).

Note: Available in Professional Edition.
