How do I get the transparency in a PNG with indexed color which has a transparent background?
I have a PNG with indexed color which is rendered with a transparent background in Google Images, so I know the transparency is there, but the color mode is Indexed, and in InDesign & Photoshop I see a white, not transparent background. There must be a setting or save method to use to bring out the transparent background in this image. What might I need to do, preferably with Photoshop?
I do not want to convert the image to RGB and remove the white background through the various possible methods, I want to preserve the perfectly smooth and accurate edge by utilizing the transparency that already exists, but is being rendered as white.
Check your alpha channels in Photoshop (if the panel isn't already visible, you can go to Window > Channels to open it). That's probably where your transparency information is being stored.
If there is an alpha channel, you can CTRL + Click (or CMD + Click if you're on a Mac) on the thumbnail of the alpha channel to select just the visible area (the white part), and do whatever you'd like with the selection.
