problem with lattice tiff or bitmap: character size and color
Hi all, I am trying to make tiff files of lattice plots at a resolution greater than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff and bitmap functions. tiff keeps panel colors but reduces axes and tick labels so they are nearly invisible. bitmap maintains correct label size but only produces greyscale. Reg...

Making TIFF images with rtiff
Many medical journals and publishers require that images, whether photographs or line art, be submitted as high resolution .TIFF images. One option for R users is to produce an image in one format and to convert it to a .TIFF file using a second software program. My experience has been that this option often results in images of poorer quality, often with blurry contours, and a loss of resolution. A second and better optio...

Wrote new tiff package, would like big-endian tiffs for testing
Over the years I have noted a couple of people interested in an R package that will read tiff files. There were some valid arguments against (e.g. R is not an image editting suite, libtiff does not support all tiff files, etc.). True enough, when I want to work with family photos, I use Gimp. But in my research I use tiffs as data sets in the context of computational biology and molecula...

viewing fax tiffs?
Hello, I have spandsp setup to accept incoming faxes and receiving tif files via Email. Using tiff2pdf, or tiff2ps -a2 or even tiffsplit, the last page of the fax is cut off and the quality of the text looks "squished". I "figure" it's a tiff parsing thing, as opposed to a problem with my spandsp installation (heh). Has anyone experienced the same thing, or can anyone...

tiff printer driver in wine?!
Hi, we need a solution for running a tiff printer driver within wine which creates tiff files from a word document, for example. Only printing through cups and/or lpr to a postscript file is doing now as known, but this is much overhead for the application we want to run. There should be a way to run such a tiff printer driver in wine....

Preparing high quality figures with tiff as end result
Hi all, I'm currently preparing some figures that will be submitted to PloS One. In their guidelines they state that they will only accept figures in tiff or eps format, with the warning that eps figures will be converted to tiff format ( see http://www.plosone.org/static/figureGuidelines.action ). Because of this conversion, I figured I'd generate tiff-format figures from the beginning. However, a number of issues cropped up: 1) using library(...

Re: SpanDSP TXFax and multipage faxes problems
Hi ! Does anyone managed to send multipage faxes (in single TIFF file) with app_txfax from spandsp package (i'm using 0.0.2pre18, libtiff 3.7.1)? If so, I'm interested in format of TIFF file that has been sent sent succesfully (tiffinfo <fax-filename>). I'm having problems with app_txfax, sending first page successfuly 99 % of the time, but n...

Is libtiff >= 4.0.0 now required by R for TIFF support?
We recently discovered that since R 3.3.0, on our CentOS 6 based cluster, R gets built without TIFF support. The last version where TIFF support was built, was 3.2.5. We have libtiff 3.9.4 installed: $ rpm -q libtiff-devel libtiff-devel-3.9.4-21.el6_8.x86_64 (Since CentOS 6 is so old, we have manually installed newer versions of some dependencies: curl 7.46.0, zlib 1.2.8, bzip2 1.0.6, xz 5.2....

Saving plot to tiff, with high resolution for publication ?
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 a graph, I am trying to save it using tiff.

Creating tiff with 1200 dpi
Hi all, I am trying to create images in R suitable for journal publication. I'd like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi. When I create a tiff file that is 800 dpi and 4x4", it works (although doesn't look good). But when I create a tiff that is the size and dpi I want, it doesn't work. I get the following error: Error in tiff(filename = "C:\\Documents and Settings\\sheppardj\\Desktop\\Manuscripts\\Figure 6c.tif",...

12-bit functionality in tiff package
Hi, We have recently been using the tiff package for reading tiff images into the Bioconductor Package EBImage. This has been extremely helpful in conjunction with other steps to eliminate dependencies on ImageMagick. However, it seems that 12-bit images are not supported. We were wondering if there are plans to extend the functionality...

Saving multiple 3x3 TIFF graphics inside a loop
Dear Friends, I have been trying to save multiple 3x3 (mfrow=c(3,3) graphics inside a loop using tiff figure format (not using PDF or savePlot functions) with no success. Could you please help? Here is a simplified example code: dat=data.frame (ID=rep(1:10,each=10),IDV=rep(seq(1:10),times=10)) dat$DV <- with(dat, 50+15*IDV) dat=dat[order(dat$ID,dat$IDV),] for(i in 1:10){ dt1 = dat[dat...

tiff(), jpeg(), and png() in R 2.7.0: problems if 'units = "in"' but default height and width
I love the new tiff(), jpeg(), and png() in R 2.7.0 but found an issue that I didn't see reported. When specifying 'units = "in"' but forgetting to change the default height and width (so the figure is unintentionally going to be 480 inches by 480 inches) I run into problems. Here's the rep...

Reading a TIFF file
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 values between 0..1....

The best way to end up with TIFF {Was: end up with WMF)
Hi all I posted a couple of days ago about how to end up with wmf files eventually in R for linux. The short answer was: you (probably) can't...and don't! The journal in question also accepts TIFF files, I am told (it's a physiology journal). So I adjust my question: What is the best way to get TIFF files out of R? It can't create them directly as far as I can tell. ImageMagick's convert can create TIFF; what is the best way to get there from R? Thru postscript first? P. --...
