One of my website's templates requires thumbnails to be a certain pixel ratio to display the image properly. I can't figure out how to select an exact pixel ratio from a larger image that I have for thumbnail purposes. For example if I have an original image at 800x600 but want to select a small portion of it at exactly 263x108 how can I make the 'box selector' tool to be exactly those proportions so that I can copy/make a new image out of that portion.
Make a new empty template at the size you want, copy the image and paste it into your new one. Adjust it so you have the portion you want
Jesus I swore I tried that before and it didn't work! I guess I was using the wrong cursor type to move the image to where I wanted it. Thanks
or you simply drag the box until that size is displayed, then you can move the selection rectangle anywhere you want on the image without changing the dimensions of the selection.
Select the rectangle tool In the toolbar across the top set Style to Fixed Size Enter in the width and height you want Click on the image and the rectangle is made, you can move it around to where you want but click+drag inside the selected area Image->Crop Save As or do whatever else you need to.
