sam2p -e:0 222.jpg 222_222.ps ±×PS README for sam2p by pts@fazekas.hu at Sun Dec 30 19:30:17 CET 2001 -- Fri Mar 22 19:25:03 CET 2002 Sat Apr 27 00:39:12 CEST 2002 Wed Jul 3 01:20:40 CEST 2002 Wed Feb 5 19:46:51 CET 2003 grammatical corrections by Steve Turner at Mon Jan 10 00:53:46 CET 2005 This is the README file for sam2p, a raster to PostScript/PDF image conversion program. This file contains a 5-minute turbo tutorial for new and impatient users (search for the phrase `Turbo tutorial' in your text editor). As of now, this README file is the only, and definitive, documentation of sam2p. sam2p is a UNIX command line utility written in ANSI C++ that converts many raster (bitmap) image formats into Adobe PostScript or PDF files and several other formats. The images are not vectorized. sam2p gives full control to the user to specify standards-compliance, compression, and bit depths. In some cases sam2p can compress an image 100 times smaller than the PostScript output of many other common image converters. sam2p provides ZIP, RLE and LZW (de)compression filters even on Level1 PostScript devices. A testimonial from Grant Ingram, UK: Anyway this is just a quick note to say thanks for writing the sam2p utility which I am using to create EPS figures of photographs for my thesis -- it works very well producing image sizes that are some 3% of the ones produced by ImageMagick. Does sam2p generate small EPS (and PDF) files? A testimonial from Tom Schneider, US: -rw------- 1 toms delila 88628 Mar 3 17:38 prototype-small.eps -rw------- 1 toms delila 7979299 Feb 24 12:25 prototype.eps Good GRIEF you have written a nice program!!!! The file is 90 fold smaller than the one from Imagemagick's convert. That image that was 90x smaller had been bugging me because it was so large that xdvi would strongly hesitate while I passed by the page. Now it just has a minor delay, thanks to you. Many thanks to Steve Turner for reviewing and making corrections to this documentation. The author of sam2p recommends his program over other image converters because of the following reasons: -- sam2p produces much smaller output -- sam2p gives the user complete control over the data layout of the output image. This includes Compression, SampleFormat and TransferEncoding. -- sam2p is fast -- sam2p doesn't depend on external libraries. (But it does depend on external programs for _reading_ JPEG, TIFF and PNG files.) -- sam2p supports the mainstream image formats of today without compromise. sam2p has many file format fine-tuning features that are missing from most other converter utilities. For example: TIFF ZIP compression, TIFF LZW compression, TIFF JPEG compression, transparent PNG files, BMP RLE-4 and RLE-8 compression, etc. -- sam2p supports all levels (versions) of the PostScript language and output images have the smallest file size allowed by the LanguageLevel. -- PostScript ZIP, RLE and LZW compression is provided for _all_ LanguageLevels (!), even for PSL1 (which appeared in 1***0). You can print your ZIP-compressed images onto your ancient printer of the 1***0s. -- sam2p supports all versions of PDF, and as with PostScript, output images have the smallest file size allowed by the version. -- output images of sam2p are always compliant to the standard selected by the user -- output images of sam2p are real-world compatible, i.e the author has tested them with many common image processing programs, for example: Ghostscript, pdfTeX, xpdf, Acrobat Reader, The GIMP, ImageMagick, xv, Acrobat Distiller, QuarkXPress, InDesign. The author has also tested PostScript files on HP and OkiData printers. -- sam2p converts every pixel faithfully, preserving all the 24 RGB bits intact. There is no quality or information loss unless you ask for it. -- sam2p uses only a minimal number of libraries. You don't have to install 33Mb of ballast software to use sam2p. Image libraries (libtiff etc.) are _not_ used, the math library is not used, libstdc++ is not used, zlib is not used. Long-term limitations: -- only DeviceRGB color space, with the Indexed, Gray and RGB image types -- Indexed images are limited to a maximum of 256 colors -- alpha channel and transparency supported only for Indexed images: only one color may be transparent -- the entire input image is read into memory. During operation both the input and the output images may be held in memory. Status ~~~~~~ sam2p is currently beta software. It is available from: http://www.inf.bme.hu/~pts/sam2p/ http://www.inf.bme.hu/~pts/sam2p-latest.tar.gz http://sam2p.sf.net/ The documentation is incomplete, but -- together with the examples -- it is quite useful. Please have a look at the home page to find articles and more documentation (the PDF docs are much more eye-pleasing than this README). The source code contains valuable comments, but they may be hard to find unless you're deeply into developing sam2p. The author is developing sam2p in his free time. (He is studying and working in non-free time.) The imaging model is complete. Image output routines are stable and adequate. Reasonable defaults are provided for all command line options. sam2p can usually find the best SampleFormat automatically. There is an educated (but not perfect) default guess for the Compression. See subsection {OutputRule combinations} about all planned formats. The most important short-term limitations: -- The code hasn't been extensively tested. The author welcomes bug reports. -- The code hasn't been profiled for speed bottlenecks. (Although it seems to be faster than ImageMagick convert(1) in most situations.) Turbo tutorial ~~~~~~~~~~~~~~ Quick compilation instructions: 1. ./configure --enable-lzw --enable-gif 2. make 3. Copy the `sam2p' executable to your $PATH, or invoke it as `./sam2p'. Quick try: -- ./sam2p examples/pts2.pbm try.eps -- ./sam2p examples/pts2.pbm try.pdf -- ./sam2p examples/pts2.pbm try.ps -- ./sam2p examples/pts2.pbm try.png -- ./sam2p examples/pts2.pbm try.tiff -- ./sam2p examples/pts2.pbm try.xpm -- ./sam2p examples/pts2.pbm try.bmp -- ./sam2p examples/pts2.pbm try.jpg A really short User's guide """"""""""""""""""""""""""" To convert an image, call: ./sam2p Example: ./sam2p examples/pts2.pbm try.eps To print an image as a full PostScript page, call: ./sam2p [MARGIN-SPECS] ps: - | lpr Example: ./sam2p -m:1cm examples/pts2.pbm ps: - | lpr To convert an image to be included as EPS (Encapsulated PostScript) into (La)TeX documents, call: ./sam2p Example: ./sam2p examples/pts2.pbm test.eps In file.tex: \usepackage{graphicx} ... \includegraphics{test} To convert an image to be included as PDF into pdf(La)TeX documents, call: ./sam2p Example: ./sam2p examples/pts2.pbm test.pdf In file.tex: \usepackage{graphicx} ... \includegraphics{test} If you have a large image file (possibly originating from dumb software), you can reduce the image size and keep the same filename. (Please note that some meta-information may be lost using this method.) This operation is _DANGEROUS_ if you don't have a backup, because due to a software or hardware problem, sam2p might clobber time image file so the actual image gets lost. To overwrite a file in-place, call: ./sam2p -- Example: ./sam2p test.tiff -- You may specify a compression method (or supply other command line options) to make a file even smaller, call: ./sam2p [OPTIONS] Example: ./sam2p -c:zip test.tiff test2.tiff See the detailed documentation of available command-line options elsewhere in this document. You may also read section {FAQ} for more information. Too see a list about the supported input and output image file formats, call: ./sam2p Example output: This is sam2p v0.39. Available Loaders: JAI PNG JPEG TIFF PNM BMP GIF LBM XPM PCX TGA. Available Appliers: XWD Meta Empty BMP PNG TIFF6 TIFF6-JAI JPEG-JAI JPEG PNM GIF89a XPM PSL1C PSL23+PDF PDF-JAI PSL2-JAI l1fa85g P-TrOpBb. Usage: [...] The list of ``Available Loaders'' lists the input image file formats. All except for JAI are self-explanatory. JAI is JPEG-as-is, it means reading a JPEG file and writing back the exactly same image into an other JPEG variant, without quality loss. From the list of ``Available Appliers'' one can derive the supported output image file formats. XWD, BMP, PNG, TIFF6, JPEG, PNM, GIF89a and XPM are self-explanatory. TIFF6-JAI, JPEG-JAI, PDF-JAI and PSL2-JAI are JPEG variants into which JAI files (see above) can be saved. While the names of the remaining appliers may be quite cryptic to the beginner user; most of those appliers provide sam2p's excellent support for writing PS, EPS and PDF files. sam2p operation modes ~~~~~~~~~~~~~~~~~~~~~ sam2p is a command line utility (i.e, without a graphical user interface), so it can be used by composing a command line with the appropriate options and parameters, and launching it. See sections ``Turbo tutorial'' and ``One-liner mode'' for more details. sam2p is not interactive, it doesn't ask questions; thus it is completely suitable for batch processing and automation. sam2p doesn't log errors, but its STDERR can be redirected to a log file quite easily. There are three modes sam2p can operate in: -- one-liner mode: (since sam2p 0.37) the user, perhaps, has to type a long command line, specifying the input and the output file name, output file format, compression options, etc. Most of the functionality of sam2p is available in a quite intuitive way in one-liner mode. Users of the `convert' utility from ImageMagick and `tiff2ps' and `tiffcp' will find that one-liner mode of sam2p is very similar to them. This mode is recommended for impatient users. Due to the nature of sam2p development, some new functionality of job mode might be missing from one-liner mode. Please report this as a bug. -- job mode: the user has to write a ``job'' file (recommended extension: .job), which specifies all conversion parameters, including the input and output file name. The name of the job file must be passed to sam2p. This mode is recommended for expert users who want to retain full control of all aspects of the final output. All functionality is available in job mode. This is especially useful in repetative but time separated jobs. -- GUI mode: This is completely experimental, and will be very probably dropped in the near future. Try executing sam2p.tk (TCL/Tk is required). Please don't use GUI mode, use one-liner mode instead! The flexability of a one-liner (or job) mode is nearly imposible to encompas in a GUI. No more documentation is provided for GUI mode. There might be a Micro$oft Windoze version of sam2p available in the near future, but very probably you won't get real GUI with radio boxes, lists and file selection dialogs. You'll have to start sam2p from the DOS prompt... One-liner mode ~~~~~~~~~~~~~~ This section contains a reference-style summary for the one-liner mode. The author knows that this section is quite incomprehensible, and a bit old. He is planning to completely rewrite it to be readable for the novice user. The order of the arguments and options is significant. Input file extension is discarded. The file format is recognised by its magic number. Output file extension gives a hint for /FileFormat: .ps :\ .eps : \ where PS: implies scale to fit page .epsi : > PSL1 PSLC PSL2 PSL3 and .epsf : / EPS: implies no scale changes [E]PS::/ also see Q9 in FAQs below .pdf : \ PDF1.0 PDF1.2 (and) PDF: : / PDFB1.0 PDFB1.2 .gif : GIF89a .pnm : PNM (for use with transparency) .pbm : PNM /SampleFormat/Gray1 .pgm : PNM /SampleFormat/Gray8 .ppm : PNM /SampleForamt/Rgb8 .pam : PAM .pip : PIP .empty : Empty .meta : Meta .jpeg : JPEG .jpg : " .tiff : TIFF .tif : " .png : PNG .xpm : XPM .bmp : BMP /Compression/RLE .rle : BMP /Compression/RLE Options (case insensitive): -- -j -j:job : display in-memory .job file -- -j:warn : be verbose and display warnings about impossible combinations in the .job file -- -j:quiet : print only error and fatal error messages, suppress warnings, notices etc. Must be put at the beginning of the command line to suppress initial banners, too.
