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

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.

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

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

I have a graphic image in a file (say a *.jpeg or *.png file) and want to put it into a plot. I have segmented the plot area by means of the layout function and successfully plotted my data in the appropriate segments. I cannot find how to put my graphic image onto the same plot. Searching the archives has shed little light on my challenge. Many thanks in anticipation. Gordon > version

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 defi...

Dear R users, in some circumstances, try() shows a strange behaviour, when the pixmap package is loaded. The following piece of code works as expected, if it is either sourced in an interactive session or invoked via R CMD BATCH (the try-error is printed). However, if i invoke R using ``R --vanilla < source.R'', the execution halts (without printing the try-error). # source.R

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

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

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?

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.

...hence also no accelerated offscreen rendering. RGB and YV12 image formats are currently supported but it's of course very easy to add support for additional formats. YV12 format requires GL_ARB_fragment_program and 8 bpp alpha only GLX pixmap support. The server doesn't provide alpha only pixmaps today. The attached patch adds an alternative PICT_a8 visual to composite and that is enough for xgl to support alpha only GLX pixmaps (not sure it will work with aiglx or nvidia's driver, I would guess not). Adding an alpha only X visual might be a bad idea. It doesn't cause any issues wi...

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

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
