Here is my expanded outline for JPS3 and PWG Raster (based on the F2F slides):
IP Policy and Minute Taker
Policy accepted with Mike taking the minutes
Approve IPP minutes from last meeting
Issue: How should we express an unknown printer-geo-location?
Issue: Need well-known URIs for standard colorspace profiles
Issue: How do we register media-col member attributes with IANA?
Issue: Need to flesh out the conformance requirements for the printer-supply attribute
PWG Raster Review
Issue: Would be nice to have total page count (if known)
Proposal: Add PageCount (integer, 0 to 2^31-1) to page header ("cupsInteger" from CUPS Raster), which is already used by several CUPS Raster printer drivers
0 means "I don't know how many pages"
> 0 means "this is how many pages are in the entire document"
Every page gets the same value
Issue: Need coordinate space of image (flip/rotate on back side)
Proposal: Add HorizontalTransform(integer, -1 or 1) and VerticalTransform(integer, -1 or 1) to the page header (“cupsInteger” and “cupsInteger” from CUPS Raster)
“Normal” pages have values of 1 and 1
“Rotated” pages have values of -1 and -1 (180 degree rotation)
“Flipped” pages have values of 1 and -1 (vertical flip) or -1 and 1 (horizontal flip)
Issue: Need bounding rectangle of any content to be imaged on the page (ImageBox)
Proposal 1: • Use existing ImagingBBox (4 x integer) from page header - simple bounding box in (integer) points
Proposal 2: Add ImageBottom (integer, 0-2^32-1), ImageLeft (integer, 0-2^32-1), ImageRight (integer, 0-2^32-1), and ImageTop (integer, 0-2^32-1) to the page header (“cupsInteger” through “cupsInteger” from CUPS Raster) - simple bounding box in pixels/lines
Issue: Some confusion about why we need pwg-raster-resolutions-support
Will be adding explanatory text to the definition
Basically supported raster resolutions can be different than supported hardware resolutions
Issue: Some confusion about the compression algorithm
Will be adding examples for 1-bit grayscale and 32-bit CMYK images to clarify
Also have sample raster files available for download
Currently at http://ftp.easysw.com/pub/cups/examples/PWGRasterSamples.zip
40MB download, 80MB worth of data
150dpi files for black-1, cmyk-8, sgray-8, sgray-16, srgb-8, and srgb-16
Representative documents for email, line art, maps, photos, and web pages
Issue: Where to place sample raster files?
