14. A method for communicating image information for display within a remote computing environment, comprising: (i) determining, by a host computer having one or more processors, a text mask 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, by the host computer having the one or more processors, the initial mask to generate an initial encoding; (iii) transmitting, via a network interface of the host computer, the initial encoding; (iv) encoding, by the host computer having the one or more processors, a refinement mask of the at least one refinement mask to generate a refinement encoding; and (v) transmitting, via the network interface, the refinement encoding, the refinement encoding transmitted subsequent to the transmitting the initial encoding, 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 comprising (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.
27. The method of claim 14 , further comprising: receiving the initial encoding; decoding the initial encoding to generate an initial display of at least one text region of the image; receiving the refinement encoding; and decoding the refinement encoding to generate a refined display of the at least one text region subsequent to the initial display.
