Thanks for another handy tutorial Trent👍.

[@pedropuckerstein4670]

Yet another excellent video - with theory of operation, not just recipe - I really appreciate that

[@TechnicallyTrent]

No problem!

[@frankbelt633]

Really helpful. Thank you.

[@sudrajad4743]

OMG I finally found this feature . 😅 Thanks

[@skins3738]

Thanks. As far as I can tell the rasterize and trim feature is for trimming off the part that hangs off the edge. The rasterize option will remove the transparent part of the image automatically. Unless you want to chop off at the edge you can use rasterize without the trim option.

[@TechnicallyTrent]

True, I should have clarified the difference between Rasterize and Rasterize and Trim. Thanks for the info!

Very helpful tutorial. I am so new to phot editing and Affinity photo and designer that I don't understand many of the commands or even wh to look for. So this video provided a couple explanations of functions about canvas and other thing that I didn't even know existed. I really need to get some instruction and come up to seed on Affinity Designer and Photo because I am trying to use the AI art in my woodworking and making projects and they often need to be manipulated before I can use them. I do lots of Epoxy art which takes very clean vectors and the CNC software I use does an adequate job but looking for a more efficient process. I'll keep looking through your videos. Do you have a recommendation on a video or playlist on how to take AI images and turn into SVGs that can be used in CNC and Laser software?

[@TechnicallyTrent]

Hi @RobSandstromDesigns , thanks for the message! I don't yet have any videos on working with AI art, but it is something I plan to make videos on because it is a process I do myself. I also use MidJourney to generate assets and then use the Affinity programs to further modify them. Stay tuned!

Obrigado, saúde e paz!

Okay I’m new to affinity. In what scenario would I need to do those two things? What did the pixel clip to canvas actually do?

[@TechnicallyTrent]

Hi @jesscolle2652, thanks for the question! It's mostly a matter of preference whether you want to trim a transparent image. But sometimes if you are embedding the image somewhere else - like on a webpage - that extra space around the edges can make it not fit well. Hope this helps!

Hi, I only have Affinity 2.55 beta and for images with no background or white background only Clip Canvas works, Rasterize & Trim does not work as you showed for images with white background. It would be interesting if Clip Canvas worked on any solid color background.

[@TechnicallyTrent]

Hi @waldowaw55, true, this method only works for images with transparency. It would be nice if in the future we get better background removal tools. Currently, you'll need to use the selection brush to manually select and delete the white background.

Clip to canvas is wonderful. I have been cropping the canvas up to fit larger images. thanks for the tip
