Pixmap package for Windows
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? Installation of other packages (I
just tried with "pinktoe") seems to work fine.

using identify() together with plot () and pixmap()
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]))

Package pixmap breaks try() under circumstances
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).

how to read individual values from a pixmap object
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)

Pixmap problem
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...

overlay two pixmap
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.

RFC: package pixmap
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

count pixels of same color in pixmap object?
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?

[PATCH 1/2] dri3: remove bogus condition for creating pixmap
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.

trouble running pixmap examples
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.

Using one buffer object per (EXA) pixmap potentially wastes memory.
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

first please excuse if I missed the answer to my question while searching

[PATCH xf86-video-nouveau] dri2, present: move in pixmap before getting addresses
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.

compiz composited video and alpha only GLX pixmaps
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
