I have a black and white images PNG (+5000) on transparent BG. I am trying to find a setting that will trace the images without creating a white block in place of a transparent segment.
I need the drawing to have white interior but transparent exterior. All I could do is get partial parts white inside with"color, automatic,ignore white"
Removal of the white block with expand is not an option, I need to make this in to action that will turn all png to svg without that white block.
I don't believe you can accomplish this with Illustrator's trace feature.
To Illustrator, white is the same as transparent. It sees them the same.
When tracing, if you don't ignore white, then white objects are created for both white and transparent areas. If you do "ignore white" then no white objects are created - and since transparent is the same as white to illustrator... well... you can't get transparent areas and white objects from a trace.
It's both or nothing.
(Probably has a lot to do with Ai being born as a print tool - where white equals transparent.)
Perhaps you can work around the problem like this:
In Photoshop:
Create an action which changes white to red, so you end up with an image which is black and red with transparent background. You could for example use Channel Mixer.
Run the action on all the images.
In Illustrator:
Trace to 3 colors with Ignore White ticked.
Expand the traced image.
Change all red fills to white. For example using Recolor Artwork.
