Free cmyk software for linux

PublishCMYK is a tool to convert RGB Pictures to CMYK. Or CMYK to RGB.

Including all formats of convert (pdf,jpeg,jpg,tiff,gif). You can use ICC/ICM Profiles to proof the colors.

This is important for Industrial printing.

Example:

If your source picture is in RGB, your source ICC must be a RGB profile. If you want that your resulting image is in CMYK your destination ICC must be in CMYK.

Pdf is not working perfect vor all OS.

ImageServer is a software for maintaining archives of images. Theres much software available to manually view, categorize and search images. ImageServer was designed to solve a different problem:
Imagine being a photographer or photo agency: You have a lot of images in many formats, all stored in a directory structure - your archive.
This creates at least two problems:
- The archive may contain different images with the same name. What do you do when a customer orders "flowers.tif" and this name exists in twenty different subfolders in your archive?
- The customer doesnt need your original 22megapixel 16-bit tiff file for his powerpoint presentation or layouting, he wants a small jpeg instead.
The first problem can be managed by assigning unique names to images every time an image is put into the archive.
The second problem is a little more difficult. Youll have to convert the requested images to smaller JPEGs. After doing that for too many times, you start caching the small JPEGs so you wont have to convert again for the next customer asking for that image. But then, you edit the original image and forget to update the JPEGs. Furthermore, its not enough to keep these resized jpegs for presentations, your customers graphics department also wants correctly downsampled eps images for layouting advertisements in QuarkXPress. So you start having two slaveArchives - one with JPEG and one with EPS images - and spend half of your day trying to synchronize the three.
ImageServer solves both problems automatically. It is a program with a nice GUI, configured to watch your masterArchive. As soon as images are put into any subfolder, theyll be assigned unique names if necessary. Afterwards, each image is read, and for each defined slaveArchive, a preview is created and saved. The same happens when an image in the masterArchive is altered. All this works completely automatically, theres nothing youll have to do; the GUI is just for being able to watch whats happening.
Main features:
- Input file checking: as soon as an image is put into the archive, ImageServer checks the extension to see whether it really is an image. If not, it is put into a specified folder outside of the archive.
- If configured to do so, an image without a suiting name is assigned a new name which is constructed of both the subfolders it resides in and a unique-per-subfolder serial number of arbitrary length.
- When detecting a change in the masterArchive, ImageServer can play a sound.
- When starting to convert an image, ImageServer can play a sound.
- ImageServer can remember the names it has already assigned to images in the past. This way, names assigned to an image A will never be assigned to another image B after A has been deleted.
- Any number of slaveArchives can be defined, and they can be in any location.
- Each defined slaveArchive can have completely different settings for the images that will populate it. Resizing or resampling? RGB or CMYK? Jpeg, EPS, PNG or TIFF?
- You can choose whether each slaveArchive should inherit the exact same directory structure from the masterArchive or whether the slaveArchives images should all be put into the same folder.
- In case dazuko missed something, you can tell imageserver to manually look into a folder. It can then either process all images in that folder or only those where slaveArchive-images are missing.

FOP (Formatting Objects Processor) is the worlds first print formatter driven by XSL formatting objects (XSL-FO) and the worlds first output independent formatter.
Apache FOP project is a Java application that reads a formatting object (FO) tree and renders the resulting pages to a specified output. Output formats currently supported include PDF, PCL, PS, SVG, XML (area tree representation), Print, AWT, MIF and TXT. The primary output target is PDF.
Enhancements:
- This release is the successor of version 0.20.5, FOPs production grade version.
- It contains the new API first introduced in 0.92 beta; support for Open Type fonts; support for the rgb-icc() function and a proprietary cmyk() function; copy/paste from PDF content using embedded TrueType fonts; support for PDF/A-1b and PDF/X-3:2003; improved Java2D, print, and bitmap renderers; and automatic support for all Java2D fonts for TIFF, PNG, print, AWT rendering.

Graphics::ColorObject can convert between color spaces.

SYNOPSIS

use Graphics::ColorObject;

# rgb to hsv
$color = Graphics::ColorObject->new_RGB([$r, $g, $b]);
($h, $s, $v) = @{ $color->as_HSV() };

# one rgb space to another (NTSC to PAL)
$color = Graphics::ColorObject->new_RGB([$r, $g, $b], space=>NTSC);
($r, $g, $b) = @{ $color->as_RGB(space=>PAL) };

ABSTRACT

Use this module to convert between all the common color spaces. As a pure Perl module, it is not very fast, and so it you want to convert entire images quickly, this is probably not what you want. The emphasis is on completeness and accurate conversion.
Supported color spaces are: RGB (including sRGB, Apple, Adobe, CIE Rec 601, CIE Rec 709, CIE ITU, and about a dozen other RGB spaces), CMY, CMYK, HSL, HSV, XYZ, xyY, Lab, LCHab, Luv, LCHuv, YPbPr, YCbCr, YUV, YIQ, PhotoYCC.
Conversion between different RGB working spaces, and between different white-points, is fully supported.

For any supported color space XXX, there is one constructor new_XXX that creates a color using data in that color space, and one method as_XXX that returns the current color as expressed in that color space. For example, for RGB there is new_RGB and as_RGB. The color data is always passed as an array reference to a three-element array (four-element in the case of CMYK). Thus, to convert from RGB to HSL, you can use:

$color = Graphics::ColorObject->new_RGB([$r, $g, $b]);
($h, $s, $l) = @{ $color->as_HSL() };

The constructor can always take a hash of optional arguments in addition to the color value, namely the working RGB space and the white point. For example:

$color = Graphics::ColorObject->new_RGB([$r, $g, $b], space=>Adobe, white_point=>D65);

For a list of all supported color spaces, call Graphics::ColorObject->list_colorspaces(). For a list of all RGB working spaces and of all white points that this module supports, call Graphics::ColorObject->list_rgb_spaces() and Graphics::ColorObject->list_white_points().
If not specified, the working RGB space will be sRGB. Many non-RGB conversions also rely on an implicit RGB space, and passing an RGB space as an option (either to the constructor or later) will have an effect on the values.

jpg2pdf PRO is the PRO version of jpg2pdf. jpg2pdf PRO offers you all the features of jpg2pdf 2.x plus these important features: convert every single jpeg to a single pdf (with -album to create a unique PDF) jpg2pdf PRO can automatic detect is the jpeg image is rgb or gray or cmyk and create the correct pdf. jpg2pdf PRO can automatic check if the jpeg image is rgb or gray or cmyk and create the correct pdf or pdf album.
NOTE: jpg2pdf PRO tries to detect if the cmyk image is made by Adobe Photoshop and will use inverted colours to create the pdf (it appears that Adobe Photoshop writes inverted data in CMYK JPEG files: 0 represents 100% ink coverage, rather than 0% ink as youd expect)
Main features:
- convert every single jpeg to a single pdf, to put every jpeg in a pdf album, like normal jpg2pdf, you can use the option -album
- jpg2pdf PRO can automatic detect is the jpeg image is rgb or gray or cmyk and create the correct pdf. Note: jpg2pdf PRO tries to detect if the cmyk image is made by Adobe Photoshop and will use inverted colours to create the pdf (it appears that Adobe Photoshop writes inverted data in CMYK JPEG files: 0 represents 100% ink coverage, rather than 0% ink as youd expect)
- center parameter will center evary jpeg image in the final pdf page
- Using image parameter (to set the paper format of the pdf page equal to the image) is possible to use border parameter to set a border around the image
- Its possible to set a directory where to put the pdfs (pdfdir) and the jpegs (jpgdir)
- Its possible to re-run infinitely jpg2pdf setting the wait seconds

Printbill is a sophistocated Unix print billing and/or accounting system with associated administration utilities. It primarily supports LPRng but now has limited CUPS support as well.
A simple print filter and accompanying daemon perform pre-printing billing, post-printing billing, print-accounting and print job quote generation. In addition, various utilities for administrators and users are provided - including programs to check your print quota and usage patterns, a web interface for both users and administrators and a command-line quote generator.
Charge rates may be specified on per-page, per-percent-coverage or both, and any number of printers/print queues can be provided (with different charge rates and printer parameters). Monochrome and CMYK colour printers are supported (with separate charge rates for both colour and black ink).
For all filters, processing can happen out-of-order, and you may prioritise jobs on the basis of size (jobs larger than a threshold can get lower priority or higher priority as desired) and jobs are billed in parallel / overlapping - jobs which finish billing first get printed first.
This is not necessarily the same as the order of arrival. Detailed stats are collected on a per-printer basis for job size, CPU time for each job, page count and ink/toner coverage, so you can analyse the usage patterns for your printers and predict when a cartridge will need to be replaced. It supports an optional user-supplied anything-to-postscript filter, so you can get properly billed for plain text, DVI files, image files, and so forth as well as PostScript.
Databases and configuration files may be stored on a centralised web server. This allows read-only access so that Unix (and conceivably Windows) clients could easily check quota, calculate quotes etc. remotely.
For fun, an additional filter is provided which allows users to deduct fixed amounts from their accounts (we use it to let students buy drinks and food from an unsecured laboratory fridge).
Enhancements:
- Finished support for per-user per-printer stats, tested that it works.
