Copy link to clipboard
Ihave a PSD file that with transparency. The background has been cleany erased. How do I use Image Trace to reference that alpha channel and give me an outline of the silhouette?
I know there is a way to accomplish it in InDesign using Clipping Mask Options, then reference the alpha channel, and then convert the clipping mask to a frame.
But how can I accomplish this in Illustrator? I am using the Silhouette preset for Image trace, but where there are white areas in the source image, they get traced. I want to somehow specify all non-transparent areas are referenced as black. This happens even if I change the threshold amount to 100px.
Sometimes the whiteareas are inside the black areas (like as with a shiny face), but othertimes, the white area is outside the face (like a baby wearing a white hair bow).
Those white areas you are asking about are sometimes hidden; actually they are not hidden. Those layers are grouped and you have to ungroup from edit navigation, simply. After that, I hope you will be able to see that area.
If you still think, it will not goin to work. Please do lemme know!
So I added a blue background so you can see how, even with the Threshold moved almost all the way up, part of the white box is still getting clipped out.
So I'm still wondering if it's possible for Illustrator to recognize an alpha channel is a plced PSD.
InDesign has this ability, and I can use it as a clipping mask, then convert the clipping mask to a frame.
Does Illustrator have the ability to do recognize the alpha channel when using Image Trace?
Can anyone tell me if Image Trace is able to reference an Alpha Channel in a Photoshop image?
If you are referring to tracing just the alpha channel and not the rest of the image: then no.
No, you cannot use an alpha channel in a .psd in Illustrator
It would be a best practice if you take any vector images for tracing as the photshop portraits or other images reqiure manual work; however we can trace other objets autmaticaly wihtin a click only. So, it depends on the images too. Mostly, I used to trace images for games like Dragon City Mod.
Lemme know if you still have any confusions related to this, please.
