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. + + +Tue Feb 24 20:00:00 UT+1 1998 +Peter Kirchgessner + +Picked up the sources because they did not find their way to the +SANE-package up to now. 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 independant from inquired + model number. + +Wed Mar 28 10:00:00 UT+1 1998 + +Bring it on its way to the SANE-project. Geoffrey accepted to add +licence informations to the files as long as noone has to pay for the code. + +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) -- cgit v1.2.3
