This is a question about image file cropping.
I recently posted a public notice to an Indian newspaper called the Free Press Journal. This is available online as The Free Press Epaper.
Now, one can download a notice that was posted in the paper as a JPG file. However, this JPG can, and in my case, does, include multiple notices. These notices are mostly long thin rectangles running vertically, filling up the image.
I'm wondering if anyone can suggest a simple approach to "slice" the segment containing the desired notice out of the image file. I could also convert to another format if it would make this slicing process easier. A method to make the image larger if necessary would also be a plus.
