First I have read this article about how to draw text in OpenGL ES(Android): https://stackoverflow.com/a/4336679/2757195
I use the same way to draw text in OpenGL ES(Android), except that I use Android JNI API.
My Problem is the text which been drawed in my demo is very fuzzy. And if I increase the size of the same font(such as times 2.0f), it will become more clearer than before. It doesn't make sense!
An example:
font size:12, the rectangle of one character in this font is: RectA(using measureText to get advance).
If the width and height of dest drawing rectangle region is same with RectA, then the character is very fuzzy.
But if I increase the size of font to 60, and the dest drawing rectangle is still RectA, then the character is very clearly.
Why?
