I can't think of anything offhand. If you do happen to be in contact with printer manufacturers, let them know that you prefer the work to go ahead as GPL. I'm not making an ironclad promise here, but from what I see now, it's very likely it will go ahead as a GPL release. > Is there any kind of interface improvement that you would require that > if we were to implement ahead of time would assist you?

Yes. The internal design of rinkj is extremely modular, and is based around a RinkjDevice object (objects in C, with function pointers defined in a public interface). There's also a similar object for writing raw byte streams. So, to print a ppm to an Epson printer, you create three objects, in this order: 1. A raw byte stream writer object, which is (generally) piped to /dev/lp0. 2. An escp2 device object, which takes in four pbm-style images, one each for CMYK (or six for a photo printer). This object is responsible for converting these pbm images to printer escape codes. 3. A dithering object, which takes in four pgm-style images, one each for CMYK (or as above). All this object does is dither (it also applies a lookup table as it goes, so that 8 bpp is sufficient -- an alternative and equally valid choice would be to bring in 16bpp input at this point). Dithering also performs scaling up. 4. A CMYK conversion object, which takes in a ppm-style image. It is responsible for RGB->CMYK conversion. A key feature of this architecture is that you should be able to mix-and-match as desired. For example, if your app happened to mix line art and images on two different layers, you could do the dithering on just the images, then combine in the line art later. I'm also interested in making it easy to integrate with other imaging api's (GhostScript comes to mind rather immediately). Here's an idea. I could make a GPL release of the code with the fun dithering stuff taken out and replaced with vanilla Floyd Steinberg. Then we could both look at the code and discuss how to integrate it. Even if there isn't an immediate GPL release of the full code, you'd still get a reasonably well thought-through modular architecture. Does this sound interesting? I'm still hacking the code, and in particular don't have the api nailed down for setting config params. So there's no special urgency to get this code out. Let me know what you think. Raph P.S. Anyone looked at the output of cat /proc/parport/0/autoprobe ? I am fascinated by the idea of auto-configuring the driver from this information. |

Date: Thu, 23 Mar 2000 11:52:03 -0800 From: Raph Levien <ra...@ac...> I just wanted to update you guys on the timeline for the release of the rinkj code. My friends at Artifex (the people who license GhostScript) are busy shaking down the printer manufacturers to see if they are interested in funding the work. After four weeks, we're going to see if there's a compelling business reason _not_ to release as GPL, then almost certainly go ahead. Well, let's hope that the result is positive. What could we do to maximize the probability of a favorable (to the free software/open source community) outcome? In the meantime, I'm going to keep hacking on the driver, concentrating on tunability for the RGB->CMYK conversion. Thus, when the code is released, it should be in pretty good shape. One of the things I'm seriously considering is building a web-accessible database of profiles for all the printer/resolution/mode/paper combinations. That should be fun! Is there any kind of interface improvement that you would require that if we were to implement ahead of time would assist you?

I just did a commit for the first stage of the gui cleanup. The major changes are that the sliders for adjusting color, saturation, etc are now in a popup called by clicking the adjust color button near the bottom. This popup is not actually destroyed until the main dialog is, but clicking its dismiss button will unmanage it to get it out of the way. I still have to figure out how to center the dismiss button. Still to come: pulling all the gui code from print.c (no visible changes), trying to tighten up the layout, and putting in a scrolled list instead of an option menu for printer types.

Date: Wed, 22 Mar 2000 14:27:26 +0000 From: Dave Hill <da...@mi...> Do any of the various colorfunc routines have any random element in them? I looked quickly and couldn't find any. If this is the case, then surely it is more efficient to code this as:- if (errline != errlast) { errlast = errline; Image_get_col(image, in, errline); (*colorfunc)(in, out, image_height, image_bpp, cmap, v); } so that the colorfunc is only called once instead of repeatedly for the same input line. Might shave a bit off the processing time if the image is being expanded a lot. True. The runtime is dominated by the dither, but this would save a bit of time. |

Is anyone here familiar with the generation of magic squares (particularly "most perfect" magic squares, where each 2x2 block sums to the identical value)? I have some ideas about using magic squares to improve dither quality, but I need to generate some to use a matrices for that purpose. They need to be linear (i. e. using a sequence of numbes between 0 and 255, not using primes or anything else). Actually, what I want is something a bit more than that, even: I want four magic squares that when stacked are "magic" in the third dimension, too. Better yet (if it's possible) would be for three of the four to have the same 3D sum, as well as all four. Even better would be 16x16 squares, where each 2x2, 4x4, and 8x8 sub-block sum to the same value (obviously each 4x4 block will sum to twice what each 2x2 block will). They don't actually have to be absolutely perfect, but the closer the better. The specific idea right now is to use this to implement variable density (the current implementation of density is broken, even though it generally behaves fairly reasonably). So what I want to do is drop some number of dots depending upon what the chosen density is. The reason I'm thinking of this kind of super-perfect magic square is so that any given region of the paper will receive on average the same amount of ink. -- Robert Krawitz <rl...@al...> http://www.tiac.net/users/rlk/ Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lp...@uu...

This is to announce the release of gimp-print (the Gimp Print plugin) version 3.1.2. This is a development release. The release notes follow: 1) Better dither quality. 2) Dither is optimized for several different types of images (photographs, continuous-tone images such as charts, line art, and very fast pure black/white rendering). 3) Tweaking of the GhostScript driver. 4) Epson Stylus Color 440 prints in softweave. In general, most Epson printers are more reliable. 5) Preliminary support for more Hewlett-Packard printers. -- Robert Krawitz <rl...@al...> http://www.tiac.net/users/rlk/ Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lp...@uu...

I have submitted the addition of the Deskjet 9xx series to the PCL driver. In the absence of any hard facts so far, I have assumed the following: Extra Resolutions: 600x600, 1200x1200, 2400x1200. 4-level printing (HP CRet) with 2 cartridges (CMYK). Max paper size: A4/Letter. Dave Hill -- Dave Hill, Kempston, Bedford UK da...@mi... davehill at users.sourceforge.net Sicth munce ago, I cutn't evun spel enjuneer, and now I are one! |

Note for gimp-print readers: Eddie sent me some files from the HP Web site. Now back to our normal programme.... Eddie, As I suspected, there is nothing earth-shattering in the files you sent me. The gimp driver uses raster graphics mode only and there is not much mention of anything to do with that. It doesn't mention anything to do with CRet (4 level printing) in the 800 series, or the contents of any of the more esoteric commands (like "Configure Raster Data" or "Palette Configuration"). I know that Martin is still working with his driver for ghostscript, as there are comments on his page about a newer version coming along. I will submit some changes to gimp-print that add support for the resolutions that Deskjet 9xx's can do, but I can't really test them!

There was some discussion on this list some time ago about CMS. I am looking into this for my scanner work. If somebody is interested, I've a version of lcms (www.coloraid.de->lcms), which was Windows software, running under Linux/i386. Marti, the author helped a lot getting this to compile and run under Linux. I've done a quick and dirty plugin for Gimp just to=20 get something to work with. So if anybody is interested in e.g. doing the RGB->CMYK transformation based on ICC profiles just let me know. Karl Heinz --=20 Karl Heinz Kremer kh...@kh... http://www.khk.net |

I'd like to do a 3.1.2 this week (maybe even tomorrow, since my wife will be busy). I might try one more dither hack first, if I feel really courageous :-) Steve Miller says the GUI stuff won't be ready before late this week at the earliest, and that's going to be a radical enough change that it might be worthwhile putting something out beforehand. We have preliminary support for some more HP stuff in there, and I finally got the Epson 440 printing 720 softweave (still not the higher quality -- the weave code still has some limitations). |

Date: Mon, 20 Mar 2000 23:47:08 +0000 From: Dave Hill <da...@mi...> The latest changes in print-dither.c (from 1.14 to 1.16) have apparently broken dither_cmyk when black is used (i.e. CMYK mode). It still works fine in CMY mode, but in CMYK mode the image "fades" towards the bottom right and the colours aren't right. Robert, if you still have the Tux logo I sent you, try printing to file using "Deskjet 500C/540C" (CMY) and then "Deskjet 550C/560C" (CMYK), then pcl-unprinting them. OK, it should be fixed now. -- Robert Krawitz <rl...@al...> http://www.tiac.net/users/rlk/ Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lp...@uu...

They both look wrong to me (the 540 looks worse). However, it looks just fine printed on my EX. What settings are you using? |

Date: Mon, 20 Mar 2000 19:07:01 +0100 From: Thomas Tonino <tt...@bi...> It might be worthwhile to try the few matrices that are on my website ( http://people.a2000.nl/ztonino/dither/files/64C for example) as the randomizing data in the FS process. It is bound to be less visible than true random noise. If the patent problems are too complicated for a production environment, I'm willing to spend a day or more on an "artistically created" equivalent. The good thing about void-and-cluster generated random data is that it is of higher frequency than normal random data: blue noise as opposed to white noise. The current dither code isn't general enough to be able to handle arbitrary matrices. It's probably worth generalizing it some time. Right now it uses an adaptive matrix (or what I call an adaptive matrix, at any rate :-) ). |

Date: Mon, 20 Mar 2000 17:37:39 +0100 From: Hrafnkell Eiriksson <he...@kv...> I have just bought a Epson Stylus Color 660. I just installed v3.1.1 of the gimp-print plugin. I see that the Stylus 660 is not listed in the setup for supported printers. Try the 640 driver. Btw. I know that you guys are trying to improve the dithering code. I just did a quick search for articles on error diffusion and inkjet printing in the online article database at my university. I found an article called "Error diffusion with ink reduction for high quality and high resolution ink jet printing" by Joseph Shu at Epson Palo Alto Labs. Have you seen it? It appeared in the proceedings of IEEE International Conference on Image Processing 1995. Thanks! I haven't seen that. PS: Is the patent situation with dithering algorithms complicated? I have no idea. I've read in a number of places that people who aren't patent lawyers should *not* attempt to do patent searches or read patents (in the US, at any rate). As best as I can retell, if you've read a patent and you get asked to cease and desist, you are assumed to be unable to determine if you're in violation or not, and must assume that you are (only a patent lawyer is deemed competent to determine if you've violated it). If you haven't read it, things are a bit different. It was really bizarre. I've heard from other sources, though, that people who aren't patent lawyers who might get into patent disputes should not read patents. -- Robert Krawitz <rl...@al...> http://www.tiac.net/users/rlk/ Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lp...@uu...
