30. A system for communicating image information for display within a remote computing environment, comprising: a host computer for (i) determining a text mask of a text region from an image, the text mask determined from a text layer and related text-background information extracted from the image and comprising an initial mask and at least one refinement mask, (ii) encoding the initial mask to produce an initial encoding, (iii) transmitting the initial encoding, (iv) encoding a refinement mask of the at least one refinement mask to produce a refinement encoding, and (v) subsequent to the transmitting the initial encoding, transmitting the refinement encoding; and a remote computer for (vi) receiving the initial encoding, (vii) decoding the initial encoding to generate an initial display of the text region of the image, (viii) receiving the refinement encoding, and (ix) decoding the refinement encoding to generate a refined display of the text region of the image, the refined display providing a more accurate visual depiction of the text region than the initial display; wherein the text mask comprises: a text pixel mask, a plurality of text pixel colors of pixels associated with the text layer, and a text-background pixel color, wherein: the initial encoding comprises (a) an approximation of the text pixel mask comprising a filtering of the text pixel mask, and (b) an encoded text pixel color determined from at least a portion of the plurality of the text pixel colors; the refinement encoding comprises (c) mask refinement information for enhancing a decoding of the initial encoding to generate a lossless version of the text pixel mask, and (d) color refinement information for enhancing the decoding of the initial encoding to generate a plurality of display text pixel colors closer in accuracy to the plurality of text pixel colors than a decoding of the encoded text pixel color; and at least one of the initial encoding or the refinement encoding comprises an encoding of the text-background pixel color.
