MATLAB: Does legend text appear outside the legend box when I use the PRINT function to save a figure as a JPEG-file in MATLAB 7.0 (R14)

exportfiguregraphicsguihandlejpeglegendMATLABposition;printresizetext;

When I export figures containing a legend to a jpeg file, the text in the legend appears outside the legend box. For example, if I execute the following code:

plot(1:10)
set (gca, 'position', [0.13 0.12 0.775 0.805])
set (gcf, 'paperposition', [1 2 4 3])
l = legend ('Plot');
print -djpeg legend.jpg

The text "Plot 1" appears outside the legend box in the jpeg. This problem does not occur in MATLAB 6.5.1 (R13SP1) and earlier.

We have verified that there is a bug in MATLAB 7.0 (R14) in the way that the PRINT function resizes the legend when the PaperPositionMode property of a figure is set to 'manual' instead of 'auto'. The PaperPositionMode property defaults to 'auto', but is set to 'manual' when you issue a SET command to change the PaperPosition property of a figure. To workaround the issue, avoid using the 'PaperPosition' property to control the size of the figure in the JPEG. Instead:

1. Draw the figure and the legend.

2. Resize the window to the size you want the figure to be when it's saved as a JPEG by using the Position property.

3. Use the PRINT command to create the JPEG.

4. Resize the window back.

MATLAB: Is the PNG of the figure rotated 90 degrees

When the 'PaperOrientation' property of the figure is set to 'landscape' instead of 'portrait', the subsequent call to "print" saves the figure as a PNG image using this orientation specification. This could result in an image that is rotated 90 degrees from the orientation of the original figure.

This can be verified with the following command (while the figure "fig" is open):

>> get(fig,'PaperOrientation')

In order to resolve this issue, you can insert the following line before the call to "print":

>> set(fig,'PaperOrientation','portrait');

MATLAB: How to make MATLAB print in WYSIWYG mode

There are several ways to ensure that your objects maintain a consistent look when printing. With MATLAB you can do the following:

1) Set the PaperPositionMode of the figure to 'auto'. The following command forces the figure's size and location on the printed page to directly reflect the figure's size on the screen:

      set(gcf,'PaperPositionMode','auto')

2) Set the figure's screen position to the same dimensions as the figure's PaperPosition.

      ppos = get(gcf,'PaperPosition');
      su = get(gcf,'Units');
      pu = get(gcf,'PaperUnits');  
      set(gcf,'Units',pu);
      spos = get(gcf,'Position');
      set(gcf,'Position',[spos(1) spos(2) ppos(3) ppos(4)])
      set(gcf,'Units',su)
