I can add the field, but since most producers of PWG Raster will not be able to supply the compressed size of the raster no printer will be able to depend on it anyways, so IMHO it is best to have the printer, if it is going to do any local processing of full page images, use its own optimal internal storage format than try to gerry-rig something into the format that just won't work.</div><div><br></div><div><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple" style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div class="Section1" style="page: Section1; "><div><div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Times New Roman"><span style="font-size: 12pt; "><o:p><font class="Apple-style-span" color="#000000" face="Helvetica"><span class="Apple-style-span" style="font-size: medium;">...</span></font> </o:p></span></font></div></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Times New Roman"><span style="font-size: 12pt; ">I would actually prefer to flag the file as version 3 which is an uncompressed CUPS Raster with the version 2 page header.

If you are trying to tweak PWG Raster for use as an internal representation format then I'd rather not put that in the standard since internal formats are OOS for any PWG standard.</div><div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple" style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div class="Section1" style="page: Section1; "><div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" face="Times New Roman"><span style="font-size: 12pt; ">Would it be sufficient to document an uncompressed version of PWG Raster (with the "RAS3" file header) and then mark the native word order support as out-of-scope for the spec but something that might be used internally?<o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" color="blue" face="Cambria"><span style="font-size: 12pt; font-family: Cambria; color: blue; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman'; "><font size="3" color="blue" face="Cambria"><span style="font-size: 12pt; font-family: Cambria; color: blue; ">[gwp] I believe the RAS3 is for the entire PWG Raster file.
