The Mac app hides rulers by default, but you can show them by selecting View > Canvas > Show Rulers or pressing ⌃ R. Select View > Canvas > Show Pixel Grid on Zoom, or press ⌃ X, to see any edges of your layers that don’t align with the Pixel Grid once you zoom in past 600%.Īn image showing the pixel grid in the Mac app (v90 July 2022) How to use Rulers If you’re working on a design where it’s important to be able to see individual pixels, select View > Canvas > Show Pixels on Zoom or press ⌃ P to enable Pixel Zoom and view individual pixels when you zoom in past 100%. The Mac app measures layers in points - where one point is equal to one pixel on the Canvas - and when you export, you can scale things to different resolutions. It’s resolution independent and you can zoom infinitely to work at any level of detail. 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.By default, you’ll view the Canvas in vector mode. 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.
