How do I generate a PostScript page ready for immediate printing with margins and the image properly scaled to fit the page?
How do I create a PostScript file that will automatically scale the image to the maximum when printed? To print an image as a full PostScript page, call:. You can set the margins individually: Example:. You are strongly encouraged to print raster images with sam2p. Other utilities may add unnecessary text banners or scale the image inappropriately. If you just want to print a sampled image alone, please use your favourite graphics manipulation program instead of sam2p.
In job mode, create a. Do the EPS files created by sam2p conform to some specifications? The EPS output of sam2p conforms to the following Adobe specifications: An excerpt: The following example illustrates the proper use of DSC comments in a typical page description that an application might produce when including an EPS file.
PostScript code for illustration.. This error message means you have requested an invalid combination of FileFormat, SampleFormat, Compression etc. If you use one-liner mode, and you're sure that you've specified your will correctly in the command line, please report this error message as a sam2p bug also specify -j in the command line. If you use job mode, please read on. After that, correct your request.
Another cause for this message is that your request cannot be applied to the image you've specified. It is possible, but very unlikely that this error message is caused by a bug in sam2p.
Example one-liners: sam2p -s:Indexed8 -c:fax test. Bad luck? Not for me. Can I use negative margins i. Even with these formats, the image is only moved, not cropped.
Please use an image manipulation program e. When I try to print the PostScript output of sam2p, the edge of the image is missing white. Many printers cannot print to the edge of the paper so that region is left white. Please increase the margins to a safe value, for example:. How do I report a bug in sam2p? Please send an e-mail to the author pts fazekas. Try to attach a file as small as possible. How long does the LZW patent held by Unisys last? I must stress that the "exact" answers you may be looking for may come only from lawyers and courts, and I am none of these.
There cannot be other new patents on LZW, as far as I know. Please let me know if you find different information. Note that you'll very probably get poor compression ratio. Examples: sam2p -s:Indexed8 -c:fax test. Can sam2p convert images with transparency to PDF? Although PDF That's because the author of sam2p hasn't implemented it yet. This means that sam2p doesn't know how to do the conversion you've requested and it even doesn't know whether the request is erroneous or not.
This might be because your request is bad it is impossible to be fulfilled , or your request is good, but sam2p doesn't know how to deal with it. If you think that the latter is the case, please report this message as a bug. Make sure you have djpeg. Make sure you have tif22pnm. I cannot open a PNG file in the Win32 version. Make sure you have png22pnm. What is tif22pnm?
What is png22pnm? It is based on the excellent pngtopnm utility, but doesn't depend on the NetPBM library only libpng. The PDF However, if the image contains at most two colors including the transparent pixel , sam2p can create a working PDF How do I build my own sam2p debian package? Please download the newest sources. How do I specify the page size when printing a. You cannot. Use -m to specify the margins. The page size is autodetected by your printer when the page is printed. So you can print the same.
If you really have to specify the page size, edit the. You might find the a2ping. How do I control ZIP compression ratio? Use sam2p -c:zip in. ImageMagick convert creates smaller PNGs. I don't know the real reason. Probably because ImageMagick uses libpng, which is smarter than sam2p.
Try one of the following compression options: sam2p -c:zip bytes sam2p -c:zip bytes sam2p -c:zip bytes sam2p -c:zip bytes sam2p -c:zip bytes sam2p -c:zip bytes convert -quality? Can sam2p convert large JPEGs to smaller ones with loss of quality and resolution? So the pixel width and height of the input and output image cannot be changed. If you need that for example you want to create thumbnails , use the famous convert 1 utility of ImageMagick.
For example: convert -scale -quality 50 in. The quality of 0 means ugly output with small file size, and the quality of means nice output with big file sizes. You can specify intermediate integer quality values 50 and 75 are recommended. Be prepared that qualties above 30 or so may not work on all JPEG viewers. If you need more control over your JPEG output, then forget sam2p, and please consult the documentation of those utilities. Yes, it can, but usually not directly.
GIF allows a maximum of different colors in an image. To check this, run sam2p, and examine its console output. It should contain a line: Available Appliers Use sam2p -c none -s rgb8 in.
Remove the transparent color within an image editor first. Yes, if you have Ghostscript installed, and your input EPS file is not too exotic. This has been tested on Linux only. Without scaling, 72 DPI is the default.
No, it can't. Emitting a multi-page document would need a fundamental change of the sam2p architecture. Should the 2nd page be compressed with a different method? What if the 2nd contains too many colors? Should we keep all previous pages in memory?
An EPS-merger would be even easier. But I don't have time to implement these features directly into sam2p soon. Can sam2p read a multi-page TIFF? The auxilary utility tif22pnm could be patched so it extracts other pages, and a new command line option can be added to sam2p that passes the required page number to tif22pnm. But I don't have time to implement these features soon.
By the way, multi-page TIFFs can be created with the following command: tiffcp -c g4 d1. There are two main problems: See also Q40 and Q The above will ensure that fax compression is used. What you need for ensuring that the output is 1-bit black-and-white is: sam2p -s:gray1:stop test. Open it in an image editing program and ensure that the colors are and ffffff only. Acrobat Reader 5. The same problem happens with Ghostscript 6. In fact, Ghostscript 7.
To ensure this, you have to re-encode the JPEG. Instead of this: sam2p bad. I also don't know of any baseline JPEG compliance testing software. But if you re-encode with djpeg and cjpeg, it becomes compliant.
Is it possible to specify a resolution other than 72 DPI, so that the dimensions of the resulting PDF are accurate for print-resolution images? Yes, it is. It would be possible to improve sam2p to use this information, but it would be too much work. To proper way of scaling an image, however, is using your DTP or word processor program to resize it properly. Is it legal to use LZW compression? I think so. Also look at Q Until someone adds a test to. This is a bad idea in general, because you lose information, since the EPS output of sam2p is always rasterized, so it is not scalable anymore.
But you may run sam2p over all those EPS files which contain raster graphics. Otherwise, choose a different filename for output. Should I run sam2p over all my PNG files, to see if they would become smaller? You might try it, there will be no quality loss, but the general experience of the author is that the tools using libpng e. If you are an image compression specialist, please help the author to find the reason of this, and enhance sam2p. This is a lossy operation, and the size of the output file depends on quality parameter specified, so it might actually become larger than the original.
Run this: sam2p -c:zip PSL2: in. It doesn't affect the rendering speed on LanguageLevel 3 devices. This is a message for seeking help when you choose this option, please fill in your Email correctly, and we will reply to you as soon as possible.

Several test runs were done on with the latest sam2p and the. This is especially useful in repetative but time separated jobs. Try executing sam2p. 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. You'll have to start sam2p from the DOS prompt 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. Set to false for debugging. Default: true. Must be put at the beginning of the command line to suppress initial banners, too. Can be specified separately e. Deprecated, please use PS:. Previously transparent pixels are not changed. See FAQ answer A44 for an exampe. The details about the output file format including standards-compliance, compression and transfer encoding are specified in the Job file and other files.
Thus, in order to make use of the basic and advanced features of sam2p in job mode, you have to: 1. Understand the basic concepts i. Decide the name of the output file. Decide some or all details of the output format. Create a Job file that describes those details. Feel free to report any issue there if you encounter one!

If there is a compilation error, send a brief e-mail to the author immediately! Command line mode is stable and it is recommended on this platform. It should work on any Linux or BSD system without modification. Porting to other Unices should be quite easy.
The author welcomes portability patches. Porting to non-UNIX systems may be hard. So the Makefile supplied won't work, and many man hours of extra work would be necessary. This call might not be available on non-UNIX systems. Compilation took , executable size: kB. To compile sam2p. Note that this will be a long download and a bloated install, but after that, just copy perl. To build sam2p: 1. Install all the build dependencies.
Open the MSYS terminal window from the start menu. Let's call this directory the MSYS home. Download the sam2p sources. Unpack the sources. Run: tar xzvf sam2p-latest. Copy perl. The file sam2p. Use it. You may copy it to another directory right now: cp sam2p. You should invoke sam2p.
Don't put it into the Start menu, it won't work. The file bts2. It is an important file, because it is required for the GUI compilation.
Don't forget to install tif22pnm. The installation instructions for these programs are not given here. Currently it can load and display images, but not cannot save them. Feel free to enhance the code. Just remember to semd me copies. You'll need Visual Studio 6. Download untarka. Run: untarka. You'll need bts2. Copy bts2. Please report and fix bugs in vcsam2p. The second P[GB]M contains the alpha channel.
Note that only the major features of these file formats are supported. The image coordinate system X,Y is defined as: upper left corner is 0,0 , upper right corner is Width-1,0 , lower right corner is Width-1,Height Some pixels of the image may be without color: they're transparent.
A transparent pixel is not painted, so whatever was left under it on the paper, remains visible. On the other hand, a colored pixel overrides the pixel below unconditionally. Notions referring to transparent pixels are: transparency, opacity, transparent, opaque, alpha channel, matte channel. Images are read from image files on disk. Not all file formats are able to specify all pixel data and metadata, so additional hints such as the transparent color or the name of the image author can be specified in Job files.
So unused palette entries, and e. For example, if an image has only two colors: and ffffff, sam2p won't allow the gray-1 sample format, but with and ffffff, it will. PSLC 3 or 4 non-transparent colors or PSLC The graph was created according to the descriptions above.

Its output on the author's machine: opaque transparent gray-1 indexed-1 mask transparent-2 gray-2 indexed-2 transparent-4 rgb-1 gray-4 indexed-4 transparent-8 rgb-2 gray-8 indexed-8 rgb-4 rgb-8 This ordering should be taken into account when someone develops her Rule Profile. This is the default. For PNG output, this is the same as what libpng uses by default. Default: null. Specify a color forced to be transparent.
Old transparency, if exists, is blacked! Default: 0. Default: 72, which means no scaling. For DCT, its value is respected: use 0 or 1 only. See DCTEncode in subsubsection 3. Each image pixel is assumed to be 1 bp wide and 1 bp tall. A TTM file is a dirty hack for generating templates with auto-calculated lengths and offsets. The elements of the array are called chunks. Each chunk causes some bytes to be appended to the output file.
Data is appended in the order the chunks are listed in the TTM file, but the data calculation order may be different. This way it is possible to write calc the length of a chunk not written filled in yet. The very first chunk has number zero. This way it is possible to write the length of a chunk not written yet. The chunk types: -- string: backtick-sequences will be substituted e. The result is appended to the output file. Only chunks already appearead may be specified this way.
Only chunks already calculated may be specified this way. This subfile contains sub-chunks, and the subchunks may be arrays themselves. A TTM file can have up to 64 top-level chunks. Use e. This was not compared here. However, if we run the jpegtran command first, then the output of sam2p becomes smaller. This can make startup time faster, and it can make it easy to install to systems without sam2p packaged. It doesn't matter if these colors are encoded as a palette or RGB.
There were no such images in this test run. The defaults of sam2p are tuned for the general use case though. No, sam2p guesses it by magic in both job mode and one-liner mode. In one-liner mode, just run:. Check that sam2p has been compiled with GIF support: run sam2p, and examine its console output. It should contain a line: Available Loaders If GIF doesn't appear in the line, please recompile sam2p with: make clean.
In one-liner mode, autodetection is magical. Just run:. I cannot read it with any programs. Compatibility notes: -- tif22pnm 0. Click Here Download File Finder.
