I have hand written initials. It looks to be something that was signed on copy paper and then the background was removed to get an alpha channel. These initials are a bit too thin to make an impact within the logo i am designing.
How do i thicken the lines without a stroke which would hurt the detail.?
Could you please post a section?
Have you tried Filter > Other > Minimum?
Sorry but i think i got it. I use Illustrator to get the desired effect. Even worked nice on the signature.
