I was using Snag it to resize my image to 7' square and then I created a canvas that was 8x10.' However, when I output the image, it was much lower resolution than the original. NOTE: when you copy the image in, SnagIt may place it outside the canvas slightly and then automatically enlarge the canvas to accommodate - so check that dimensions haven't changed when you past it in. Here is a workaround I found and also got some algebra help from my daughter to get the dimensions correct.ġ) Create a new image in the dimensions you want.Ģ) Open your image and copy and paste it into the image canvas you just created.ģ) Right click image and select Align/Middle AND Align/Center To get it centered, I have to drag side multiple times to get the right white space on each side. In my scenario, I wanted to take a 7' x 7' photo and center it on an 8x10' canvas. There are some offset-type parameters to sips, maybe there is a way to put the original image top left? In any case, you can cut and paste it to move it where you want it.It would be really great if SnagIt would add a capability for the Mac version to adjust the Canvas Size by entering dimension vs. If you don't specify an -out argument, it modifies the file directly rather than copying it. sips -padToHeightWidth 1000 950 -out Īnd then I later pasted something else to give you an idea of the result. (I did not have to query the size info, but I found I would always underestimate it (it's based the mac's native pixel resolution), so kept on truncating it instead). So, it's 174x950 and I want to make give more vertical space. I took a screenshot, of this page.īut now I want to stretch it a bit to add some more space to cut and paste stuff. OK, not saying this is the greatest, and still experimenting with it, but you can use the built-in sips terminal app if you know how big the image has to be and you are tolerant of cosmetics.
