Fri Dec 5 18:10:52 PST 1997 Geoffrey T. Dairiki Here is a new HP backend. It's name is, appropriately, ``newhp''. It is still in the pre-alpha stages but mostly works on my ScanJet 5P. It is completely untested on other scanners, but might hopefully work on ScanJet models IIp, IIc, IIcx, 3p, 3c, 4c, 4p, and 5p. I've only really tested this with xscanimage. Some features included in this backend which aren't in the old HP driver are: Support for custom tonemaps (gamma-maps). For some reason I can't get the 10-bit tonemaps working with my 5p, so for you only get a single tonemap (it still works in color mode, but you don't get individual control over each R/G/B channel.) You can enable the scanjets "Auto Threshold" mode when scanning line-art. I can't notice that it does much though.... Added an option to control the scan speed. Added an option to select the dither pattern used in half-tone mode. I don't think that custom dither patterns are working correctly, and in any case, with the current front-ends, there is no convenient way to set a custom dither pattern.... Added an option to select the color correction matrixes. This also seems to be flaky. Again the current front-ends do not provide a decent way to adjust the custom color matrix.

And because I want to have a better support for the HP Photosmart Photoscanner. Renamed the backend from newhp to xhp just to get a better acceptance. Added an option to perform calibration. Upload and download calibration data Added options for horizontal/vertical mirroring. Vertical mirroring is performed by loading image completely into memory before sending to frontend. Uses SCSI-flushing more often because otherwise the scanner did not accept all of the commands. Test support of commands to be independent from inquired model number.

Sun Jun 07 15:00:00 UT+1 1998 Added unload button Fixed problem with custom gamma table Sat Nov 14 14:00:00 UT+1 1998 Show calibrate button on Photosmart only for print media Add HP 6200 C Suppress halftone mode on photosmart (it is not supported)
