Can I get the default color map ?
I've been doing some analysis of some grey scale video images in labview.
When I display the images using the "Draw flattened Pixmap" vi, I leave the color map terminal
unwired and get a really useful display, with Labview's default color map enhancing the contrast in the monochrome images very nicely.
I now want to write these images to disk, so I can re-assemble them into an AVI file, unfortunately in order
to get the bmp files on disk to use the same color map as the on-screen display, I'd need a copy of the default color map...Can I use transparency as a fill color????
I got some clip art that are jpg files with a white background. I was able =
to add a transparency channel and started to use the erase tool to chnage t=
he white background to transparency, is thier a way to set the fill color t=
o transparency and just use the paint bucket to chnage the white to transpa=

I was using the "filledcurves" option to plot a filled polygonal
set style fill solid 0.1
This gives me a solid fill of red by default. How do I change the fill
color? I checked the documentation and it mentions that the region
would be filled with the current default color.
How do I change this to, say, gray? And then how do I revert?
I did try the manual and demos; maybe I just didn't find the relevant

In taking a look at a very old topic...This doesn't prove helpful to me at all, perhaps it is needed to only have 1 ROI for selection and filling.<img src="http://forums.ni.com/attachments/ni/170/308335/2/roi%20scratch.jpg"> This image is a brush scratch and the ROIs need to be filled to bring the multiple scratches into one solid scratch. Simply filling the ROIs with a 255 pixel count and redrawing the image is what needs to be done. Each attempt of mine simply results in one of the ROI selections being displayed and/or filled with a 0/255 count.The VI ...How can i display an initial color of extracted region?
i use label2rgb at the end of my program to display a region of interest extracted.
but color region displayed is not appropriate.
i want to display this region colored with other color (like its original one)and to have black background.

I'm using gnuplot 4.2 to create a stacked histogram, and I haven't
been able to figure out how to get anything other than the default
colors. I had assumed there would be something analogous to
set style line 1 lt rgbcolor <colorspec>
for the fill colors, but if so, I can't find documentation --- and
the documentation I _do_ find about fill colors frankly might as
well be in Greek.
P.S. Details, for anyone who might care:

I'd like to generate maps of the U.S. on the fly, in which each state is colored
according to info stored in a database. Like this:
That pages generates the image from a script like so:
The image map coords are included in that page for the rollovers, so I imagine
there's a way to employ them in the image generation script as well.

I want to label the pixels of each color region. To get it separated I need to draw a thin line between different color regions. Is there anything in Matlab that used to automate this task? and How?

Is there a LaTeX2e-package by means of which you can create
nested color-shaded regions that can break across pages?
I would like to use this for documenting source-code-listings
-e.g. TeX-macros or Pascal/C++ :
Structures at deeper levels, e.g. procedures/functions/macros
often have the same name. If you work in TeX, macros can even
redefine themselves during execution.
I would like to have in the documentation thereof each new
definition within some shaded area -- by using shade-areas and
colored boxes, you can in such cases point out the definition
which is intended to get applied....
