I have about 50 .jpg files from which I need to select part(s) of each image and save the selections as separate files. There is nothing constant about the size or offsets of each such selection.
Using display, its menus allow one to draw a rectangle around each desired area and save just that to file, but the saved file is distorted because the image has been stretched to the size of the original file. How can I save it with its true size?
If I need to use 'convert' to do this, how can I get the dimensions of the selected rectangle from 'display'? It shows only the offsets of the selection.
display: crop and save selection as a new canvas
Re: display: crop and save selection as a new canvas
You can do this using but noone in their right mind would ever choose to, its such a laborious process, manly because the display menu bar half covers the widget showing the geometry and offsets of one's selection.
You can also do it using gimp through a somewhat laborious process.
But you would choose to do so using xv, whose process is simple, direct, obvious and does just what you might expect it to, as opposed to the subject of this forum
