similar to: rgb to cmyk conversion is wrong in src/library/grDevices/src/devPS.c (PR#11509)

Please do study the FAQ and posting guide: R 2.7.0 is not the current sources, and this was changed a month ago in R-devel. You were asked to check for such changes before submitting a report. Also, there is no unique way to do undercover removal in conversion to CMYK, and so it is wrong to call any method 'wrong' -- in fact the one used in earlier versions of R was a documented

dear R experts---I am struggling with the requirements to prepare my files for my printers. I am printing in 2/2 format, which means cyan and black for me, which they take from my color-separated pdf files. R comes into play, because it produces all the figures that are embedded in my book (pdflatex). now, TeX has no problems producing CMYK files. However, R produces RGB files (for

Hi We are about to publish a book, which contains figures made with R plots. An important detail that we did not take into account is that the book will not be printed in 4 colors (cmyk mode), but only 2 (black +"spotcolor"). The spotcolor we use is part of the big Pantone family. The problem is that both pdf() and postscript() offer either rgb or cmyk, but no spotcolors such as

Hi, I tried PDF writer , but it doesn''t have HTML to PDF Converter. Infact it is a PDF writer itself not a converter.. I''ve HTML pages with rich css or Strings with html+css such that they are converted to PDF. The idea is that web is all about RGB color model and when it comes to Digital Printing its all CMYK color model. My html page with rich css in

Dear Erich and John, thankyou for providing RColorBrewer! Are you working on options for CMYK or RGB return values? Thanks again, Darren [[alternative HTML version deleted]]

hi! I would like to produce simple black and white postscript figures for publishing. A black/white or grayscale or CMYK colormodel can be used, but not RGB colours. Can I produce postscript graphs in R that satisfy this? Following an earlier advice on the help-list I have tried using Photoshop to convert - but this seems to convert the vector format into raster format - giving larger,

A recent article in the earth science literature cited below and available at http://geography.uoregon.edu/datagraphics/EOS/ points out that rainbow color schemes and mixtures of green and yellow can be troublesome for people with color-deficient vision. The authors propose alternative schemes that can be viewed and downloaded in RGB, HSV, CMYK, and RGB256 formats from

Hello all. A Journal we are sending an article to is asking for the following: To ensure the best reproduction quality of your figures we would appreciate high resolution files. All figures should preferably be in TIFF or EPS format... and should have the following resolution: Graph: 800 - 1200 DPI Photo: 400 - 800 DPI Color (only CMYK): 300 - 400 DPI (DPI = dots per inch) Since I am sending

Greetings all - happy new year, I''m having problems getting Pdf::Writer image insertion. pdf.image "/path/to/images/logo.jpg" is firing "JPEG marker not found!" Originally created the RGB (8 bit) JPEG in photoshop. After the above, I''ve exported with an alternate tool using (OSX) preview. This tutorial

My goal is to create a graph with one column and three rows into a single graphic. The mfrow, mfcol, and layout functions all have the same effect: three graphs are produced in a single pdf file, having one graph per page. This is not what I want (I didn't want multiple pages). Just before I sent this post, I was able to generate the desired output with split.screen. Is this the expected

Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous

Hi all, is there a way to automatically convert uploaded images to an RGB colorspace? I have a small intranet app, in which people can upload images. Sometimes a large 300dpi CMYK image intended for print sneaks in and causes trouble... Many thanks in advance, Nicky

Hi all: Since our designer friend Tuomas Kuosmanen (tigert) already did the hard work of specifying the CentOS logo colors in HEX, Pantone, and CMYK ... I did the small step of adding them to the wiki. This might be useful for you all to know it's now there: https://wiki.centos.org/ArtWork/Brand/Logo#logo-colors Also, I put a link back to the trademark guidelines for questions that are

hi all I guess that *Theora* will convert the input color space (RGB or CMYK or any) into YUV before it process and encode. (that means theora can operate on several color space, but it get convert into YUV before process) Is that true...? I want to get a gray scale, encoded video output from the *Theora* encoder while the input video is getting from a web cam (color input and gray scale

Hello all, I discovered that the pdf device uses fonts to represent "points" symbols (as in plot(...,type="p",...) ). Namely it uses ZapfDingbats with symbol U+25cf. This can lead to problems when the font is not available, or available in another version (such as points being replaced by other symbols, or worst: slightly displaced). Furthermore, it also causes
