So I'm trying to create a few simple buttons in Adobe Illustrator for work. I'm not a gphx artist and just know the basics of Illustrator. I tried creating a pin icon, like dropping a pin onto the map. I created my 20x20px document, dragged a rectangle and a circle. This screenshot shows my pin, and two of Apple icons next to it (trash can and action button).
Apple's documentation says this to describe creating buttons:
The images displayed on the bar are derived from this image. If this image is too large to fit on the bar, it is scaled to fit. Typically, the size of a toolbar and navigation bar image is 20 x 20 points. The alpha values in the source image are used to create the images—opaque values are ignored.
I feel like my button just isn't sharp like theirs. Is there something else I need to do in order to make my pin look sharper? Thx!
