Hello,

I would like to print letters centered in the figure. I works when I use the GUI, but it does not work via commandline. Since I have to print a few hundred of this figures, I would prefer to not do this manually.
Here is an example code:

figure('position',[1,1,800, 600], 'unit','pixel');
a = axes('unit','pixel','Position',[0 0 800 600]);
[d] = get(a,'xlim');
[e] = get(a,'ylim');
axis off
text('String', 'N',...
'Color',[0 1 0],...
'FontName', 'Arial',...
'Position',[d(2)/2 e(2)/2],...
'HorizontalAlignment', 'Center',...
'VerticalAlignment', 'Middle',...
'FontSize',48);
print(pic,'-dtiff', '-r600','testN');
saveas(pic,'testN.tiff');
print(gcf,'-depsc2', '-r0','testN')

Printing it using the code above does results in a figure displaying the letter moved to the right.
If I use the GUI and specify: "ExportSetup" => "size" => "Expand axes to fill figure" and "Rendering" => "resolution" => "screen", "keep axis limits", and then "Apply to Figure", and finally "export" the resulting figure appears like on the screen.
In the Help I found as an option supposed to print with screen resolution '-r0', but apparently, it does not work for me.
Does anybody know how I can use the above mentioned options from the GUI in the commandline?

Thank you very much in advance for help!

Export_fig (http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig) is a function that aims to export figures as they appear on screen.

Thanks Oliver!

I tried it and it seems to work, I have just one more problem: the pictures are saved transparent. The white background color is not saved. Why? Even if I specify the background color. See:

pic = figure('position',[1,1,800, 600], 'unit','pixel');
a = axes('unit','pixel','Position',[0 0 800 600]);
[d] = get(a,'xlim');
[e] = get(a,'ylim');
set(pic, 'color', 'white');
set(pic, 'InvertHardCopy', 'off');
axis off
text('String', 'I',...
'BackgroundColor', 'white',...
'Color',[1 0 0],...
'FontName', 'Arial',...
'Position',[d(2)/2 e(2)/2],...
'HorizontalAlignment', 'Center',...
'VerticalAlignment', 'Middle',...
'FontSize',48);
export_fig(pic, 'test', '-tif', '-png', '-bmp','-r90', '-m1')

Actually, it appears as if only the letter is saved. Or am I mistaken?

Yes, the backround is cropped by default. You can disable this using the -nocrop option. The background is only transparent if you set the figure color to 'none'.

THANKS! That is THE solution! You saved my day!
