How to avoid transparent background converting to white in smart object(psb )when image trace High Fidelity as we have the option of ignore white upto 16 colors trace.

Question

i have a psd image file in photoshop cc 2014 that has transparent background layer. I wanted it to convert to vector. The best option i saw was to first convert it to smart object in photoshop via Layer->Smart Objects-> Convert to smart Object. then exported it to a psb. Then i opened the file in illustrator and applied the image trace tool but the transparent background got converted to white but i had the option of ignore white upto 16 colors trace. But in case of High Fidelity Conversion, the ignore white option is not available, what should I do now?

Answer 1

after using  high fidelity image trace  i hit expand, then i went to layers and hit the drop arrow by my thumbnail, which then shows <Group>,hit that drop arrow and it will show a list of all your paths, the very bottom one was my white background, you can click the eye or delete that path and it disappeared for me. i was using a png file with a transparent background, and nothing else worked for me, it always converted with white background, i never saw this mentioned anywhere, and accidentally discovered it, hope it works!!!
