I want to print a per mil sign (‰) with Gnuplot. I am using postscript output terminal. I tried with 'set encoding utf8', and then call the per mil sign with {u+2030}. This does not work.
I do not have pdfcairo available as an output terminal.
Below are the available terminals on my MacBook Pro.
gnuplot> print GPVAL_TERMINALS
canvas cgm context corel dumb dxf eepic emf emtex epslatex fig hpgl latex mf mp pcl5 postscript pslatex pstex pstricks qms svg tek40xx tek410x texdraw tgif tkcanvas tpic unknown vttek x11 xlib xterm
You can obtain a "per mil" symbol with the postscript terminal using special character {\275}:
set term postscript enhanced
set output "out.ps"
set xlabel "{\275}"
plot x

I want to output a high-resolution figure from Matlab.
I tried to "save as pic.eps". But when I insert this picture in latex, it seems that the picture is not "real eps" in the sense that I can tell that the resolution is not enough.
I also tried to "save as pic.pdf". The resolution meets my demand, but the pic is cropped, as it is too large.
Then I used
print -depsc -tiff -r300 -painters pic.eps
This gives me the high-resolution full picture, but some of the dashed lines in the original picture disappeared. I have tried many other cases and still couldn't find the right way to solve my problem. Any suggestions are highly appreciated
I'd try to save eps in vector format, or use a vector only format such as .svg.
For example,
print -depsc2 -painters test.eps
These are the vector graphics supported formats according to the current documentation:
Option Vector Graphics Format File Extension
'-dpdf' Full page Portable Document Format (PDF) color .pdf
'-deps' Encapsulated PostScript (EPS) Level 3 black and white .eps
'-depsc' Encapsulated PostScript (EPS) Level 3 color .eps
'-deps2' Encapsulated PostScript (EPS) Level 2 black and white .eps
'-depsc2' Encapsulated PostScript (EPS) Level 2 color .eps
'-dmeta' Enhanced Metafile (Windows® only) .emf
'-dsvg' SVG (Scalable Vector Graphics) .svg
'-dps' Full-page PostScript (PS) Level 3 black and white .ps
'-dpsc' Full-page PostScript (PS) Level 3 color .ps
'-dps2' Full-page PostScript (PS) Level 2 black and white .ps
'-dpsc2' Full-page PostScript (PS) Level 2 color .ps
you'll also have to use the '-painters' renderer when saving vector graphics files. If you save to a vector graphics file and if the figure RendererMode property is set to 'auto', then print automatically attempts to use the Painters renderer. If you want to ensure that your output format is a true vector graphics file, then specify the Painters renderer. For example:
print('-painters','-deps','myVectorFile')
this command in question may come from the following link
After removing -tiff, my issue of missing one line was fixed (even though I don't understand what is '-tiff' for)
In Matlab, I am using LaTex interpreter as default and CMU Serif as in Latex as my default font through the following commands inside startup.m.
set(0,'DefaultTextFontname', 'CMU Serif');
set(0,'DefaultAxesFontName', 'CMU Serif');
set(0,'defaulttextinterpreter','latex');
The plot produced from Matlab appears like this, with the fonts in place:
However, upon saving the above image as eps using either print or saveas command produces figure with all the ticks and label in a different font:
Can someone suggest, what is the issue resulting in different fonts?
So recently I decided to not use the standard markers that Matlab provides and use my own via: a set of fonts including Webdings or WingDings. I make a standard scatter plot, and plot the text (in wingdings), using the text command, over the locations of the markers.
When I save these plots as png files, they print perfectly. They also appear perfectly on my screen after plotting.
However when I save these plots as eps files, the webdings are turning into their original letters 'l' or 'w'. It also looks like it's plotting them in a Courier font, but my default is Helvetica.
I've read through this previous post, but my question differs in that he is looking to use Latex as the interpreter and to include fonts, whereas I don't want to use Latex as the interpreter. However, it seems like my default interpreter (not sure what that is), isn't doing the job when converting to EPS.
Example:
imageR='w'
text(xf2,yf2,imageR,'fontName',font,'FontSize',fontR,'HorizontalAl','left','color','w')
I figured it out....took me way too long.
Ghostscript / Postscript only export with a few fonts when you are exporting eps files.
This link was incredibly helpful.
I just switched from wingdings/webdings to ZapfDinbats...Practically the same thing...
A command of the form xlabel('$<stuff>$','interpreter','latex'); will produce an axis label that is typeset by TeX using a font that is presumably ComputerModern. However, the axis tick labels (e.g., 0, 1, 2, ...) appear in the default font (Helvetica?). I would like to synchronize all the fonts in the figure (preferably to ComputerModern).
Toward that end, I presume that a command of the form set(0,'DefaultAxesFontName', '<fontname>') may be useful. However, I need to know the exact name or path of the font used by the MATLAB TeX interpreter. How can I retrieve a string value for the font name or a path pointing to the font file for the default figure font and the default TeX-interpreted font?
You could also plot the axis ticks with latex, look here:
http://alex.bikfalvi.com/research/latex_in_matlab_ticks/
Actually, your command was right to mget the default font (when NOT using latex):
get(0,'defaultaxesfontname')
But I didn't find any to get the default latex font. Perhaps it would be possible by using the internal java routines (to get some ideas, look at http://undocumentedmatlab.com/)
You can download the computer modern font, and install it on your local machine. For Mac, you'll need to download the OTF format (i'm not sure on windows machines).
Then, researt matlab, and you can use
set(0,'DefaultAexsFontName', 'CMU Serif')
to make things look like latex font.
I'm trying to use Ghostscript and/or ImageMagick to convert each page of a Postscript document into PNG images. The problem is that both produce images that are way too saturated (I think that's the right terminology).
Here are the commands I'm trying:
gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dGraphicsAlphaBits=4 -sOutputFile=page_%02d.png brochure.ps
convert brochure.ps im_page_%02d.png
This is the input Postscript file (brochure.ps from above)
Here's a couple of the output images I'm getting:
Page 1
Page 6
As you can see (especially on the page with the big green map of New Hampshire), the colors of the output PNGs are too bright/saturated. How can I prevent the colors from being changed so much and get a more accurate conversion?
Preview in OS X 10.6 automatically does a very accurate conversion to PNG when you open a Postscript file in it. This leads me to believe there is just something screwy with the way ghostscript converts ps->png (I'm fairly confident ImageMagick is just a wrapper for ghostscript for this operation). Is there a tool besides ghostscript I should be using instead?
Note: As pipitas points out below, the visible difference of colors varies by OS. It is very obvious in OS X 10.6, but apparently not very noticeable in Windows XP.
You are right in assuming ImageMagick just being a wrapper for Ghostscript when converting from PostScript or PDF to an image format.
I think, this problem can only be solved to anybody's satisfaction once the efforts to add support for ICC profile handling and color management (currently underway) are completed for Ghostscript (design document as PDF). That point in time is close, however. If I understand recent commits to http://svn.ghostscript.com/trunk/ correctly, the next release (which will be dubbed 9.00 and out hopefully in August) will include support for color management via LittleCMS. Yay!
OSX 10.4 and up provide sips (scriptable image processing system) and it works well with PDF format. Perhaps it can be a temporary solution until Ghostscript supports color management.
