I'm trying to do something for work that should be very simple, but it's turning out to be far more complicated than I had hoped. I have a jpeg of a Japanese kanji on a white background. I need to have the black kanji without the white background.
I've checked and tried everything I can think of for removing the background. I have used Krita, Photoshop, Illustrator, Fireworks... One of two things happens:
a) The program CANNOT differentiate between the white and black areas of the original jpeg using magic wand, convert colour space, etc.
b) The program CAN differentiate between them, but even with feathering selection and refine edges in PS, the resulting image is blocky, pixellated and has grey squares around it. The kanji in the original image with a white background has sharp, smooth edges and there is no grey.
Here are the two kanji compared in Illustrator. With the right image, I used PS, quick selection tool and refined the edges to attempt to remove the blockiness. (Following this older post: Photoshop: How to make background transparent without affecting image quality?) I need it to have a transparent background, but have edges as smooth and as crisp as they are in the original. I just have no idea what else to try...
Please try to keep your suggestions limited to the programs I have mentioned unless you really think it is impossible to do without acquiring something else.
