Hi, I'm having trouble writing .pnm images which I think is due to a problem with my colour space. The pixmap object seems to be looking for 72 of 8 colours (one per cell?) which doesn't seem healthy... > library(pixmap) > x <- pixmapIndexed(rep(1:8, 9), nrow=6, col=rainbow(8)) > x Pixmap image Type : pixmapIndexed Size : 6x12 Resolution : 1x1

Hi All, I have a greyscale image that I am reading in through RGDAL and placing in a pixmap object. As an example use the logo.jpg file that comes with the RGDAL package: #Read the file logo <- system.file("pictures/logo.jpg", package="rgdal")[1] x <- new("GDALReadOnlyDataset", logo) #Create the pixmap object xGrey <- getPixmapGDAL(x) Now I would

Hi I need to overlay two pixmaps (library (pixmap)). One, a pixmapGrey, is the basis, and on this I need to overlay a pixmapIndexed, BUT: the pixmapIndexed has set only some of its "pixels" to an indexed color, many of its pixels should not cover the basis pixmapGrey pixel, means, for this "in pixmapIndexed not defined pixels" it should be transparent. What would you

Full_Name: Wolfgang Huber Version: 1.5.1 OS: Windoof 2000 Submission from: (NULL) (193.174.62.11) Hi, Trying to install the binary distribution (zip file) for the "pixmap" package, as downloaded today from CRAN, I get the following warning "error -1". The package will not be installed. Installation of other packages (e.g. pinktoe, acepack) worked fine. The warning or error

There is a new package pixmap in $CRAN/src/contrib/Devel which provides a first shot at a class hierarchy for bitmapped images (as both bitmap and image are already taken I named it pixmap ... if somebody has an idea for a better name, please let me know). This is by no means meant to be final ... more like a basis for discussion about classes for that purpose. It already has RGB, indexed and

Not clear what the depth % 8 was trying to protect against, but it was breaking 30bpp visuals with DRI3. Add it in to ensure that bitsPerPixel % 8 is 0, since there is plenty of bpp/8 math in the driver.

Dear all, I try to figure out how to use R to count the number of pixels of the same color in some gray-level picture. I managed to read it in either tiff or jpeg format, but the returned pixmap object keeps its information out of (my) reach. Is there an easy way to tabulate the different color/graylevel pixels and their numbers? Or should I use a completely different (free) software?

I am having trouble running the 'read.pnm' examples in this package. Can anyone tell me what is wrong? I am using the current package and running Redhat 7.2 (intel). The other examples seem fine but I can't seem to pull in files.

Hi R users: I got the following message when I use the pixmap library on R 1.7.0 over w2K platform (on R 1.6.2 it runs right). pixmapGrey(matrix(c(0,1),128,128)) Error in .class1(object) : Object "from" not found I download the library .zip file from: http://cran.r-project.org/bin/windows/contrib/1.7/pixmap_0.3-2.zip Other question: When I try to "Install package(s) from

First of all, we were not forcing the pixmap to be moved in before attempting to present it. Secondly, in certain configurations, we avoid ever backing pixmaps with vram (in GPUs with 32MB of VRAM or less). This fixes the observed cases where we ended up assuming that a bo was backing a pixmap without doing the explicit move-in. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> ---

Is it possible to get pixmaps of minimized windows? I don't want to use ugly hacks like "temp unminimize" just to get it. Stjepan

I've been doing some testing and it seems that glyphs (typically smaller than a page size on nv50) render slow'ish sometimes, mostly due to the many trips to the kernel (drm_addmap_core is the symbol that shows up). Ofcource this was a benchmark, but it does leave me wondering, do we really need need to call the kernel for every little pixmap? Also from a memory point of view, because a

Dear R users I have a two-dimensional array, whose values I want to plot, using the pixmapGrey class. Plotting works fine, and now I would like to be able to identify some of the points in the plot using identify(). But I get the following message while pressing the left mouse button: > plot(pixmapGrey(fmri.vtc[,,slice,volume])) > identify(fmri.vtc[,,slice,volume]) warning: no point with

I've added a simple plugin to compiz that provides a way to render video efficiently on a composited desktop. A video playback client basically copies video data to a pixmap and sets an X property on a client window that describes the image format of the data and where it should be rendered. The compiz video plugin will scale and perform necessary colorspace conversions when compositing the

Hi, I tried to install the "pixmap" package on R 1.5.1. running on Windows 2000, but all I get are the following errors - could it be that something is wrong with the build of this particular package?

Dear list, here is a problem I met when trying to use a method for an S4 object, without loading the package in which the method was defined. I do not know if this is a bug, or a mistake of mine. Normally, I think the package in which the appropriate method is defined is loaded automatically when calling the method. The problem is that if the package is indeed loaded automatically, the

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the
