    <p>This question kind of starts where <a href="https://stackoverflow.com/questions/575475/how-can-i-save-an-altered-image-in-matlab">this question</a> ends up. MATLAB has a powerful and flexible image display system which lets you use the imshow and plot commands to display complex images and then save the result. For example:</p> <pre><code>im = imread('image.tif'); f = figure, imshow(im, 'Border', 'tight'); rectangle('Position', [100, 100, 10, 10]); print(f, '-r80', '-dtiff', 'image2.tif'); </code></pre> <p>This works great. </p> <p>The problem is that if you are doing a lot of image processing, it starts to be real drag to show every image you create - you mostly want to just save them. I know I could start directly writing to an image and then saving the result. But using plot/rectangle/imshow is so easy, so I'm hoping there is a command that can let me call plot, imshow etc, not display the results and then save what would have been displayed. Anyone know any quick solutions for this? </p> <p>Alternatively, a quick way to put a spline onto a bitmap might work...</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
