MATLAB: Print an image with a fixed size

MATLABmatlab_bugprint

Hello everyone,

I would like to print an emf-file with a fixed size of 21x12cm:

hFig = figure; 
set(hFig, 'PaperUnits', 'centimeters');
set(hFig, 'PaperSize', [21 12]);
print(hFig,'-dmeta','testfile');

But the created image has only the size of 13.4×10.1cm! Why it doesn't work?

Many thanks in advance for your help!

You should use the 'PaperPosition' property to adjust the output size, not 'PaperSize'. However, even if you make that change, you'd find that it still doesn't work. There's a bug report about it: http://www.mathworks.com/support/bugreports/231161.

While the print command doesn't give you the correct size when exporting to an EMF-file, the File -> Export Setup... dialog will get it right. If you don't have too many figures to export, that might be something check out.

It could be the renderer. Try

get(handles.figure1,'Renderer')

for both types of plot and see if they're different. The reasons for this are beyond me, but a while ago I tried changing the renderer on a figure because the colorbar was being weird- it fixed the colorbar problem but when I went to print, a blank sheet came out.

MATLAB: How to force output of large figure to not be “scaled”, or how to properly print a pdf whose dimensions won’t fit on the [small] screen

I got a work-around.

The issue seems to be that figures are automagically resized when they don't fit on the screen, and this messes up any kind of placement of uicontrols, axes, etc. on the figure.

The workaround is to determine a safe length scaling factor based on screen resolution reported by

ScreenSize = get(0,'ScreenSize');
SPPI = get(0,'ScreenPixelsPerInch');
SH = floor((ScreenSize(4)-200)/SPPI);
SMult = SH/(PaperSize(2));

And scale all lengths and positions of uicontrols in the figure by this amount.

The next step is to rely on the behavior of

print -fillpage

which asserts a 0.25" margin but otherwise fills the page, and so define our figure on screen as

printMargin = 0.25; % immovable 0.25" margin with print -fillpage
FigureSize = (PaperSize-2*printMargin) * SMult;

This seems to work reasonably well...so far...
