There are some handwritten notes apps like Noteshelf that have very smooth lines, no matter how thin or how magnified the strokes are, they don't blur. Any ideas ?

u mean that they are not using OpenGL? It must be very difficult to Draw line with velocity using CAShapeLayer.

In JotUI, instead of using images as brush textures, just draw a lot of dots(maybe GL_POINTS?), If this will make the blur better?

Hi adam, I worked a few days and now using another way to make the strokes clear. When a stroke ends, i render a stroke image , double the stroke...

I found that the problem should be in the size of `Context`. The cut part is always on the top or right side, corresponds to the opengl coordinate system. Is...

I used CAShapeLayer, but I found it to be just a fixed-width path, unable to reflect the thickness of the stroke when accelerating, and I want to customize the various...

I call the state's method `finishCurrentStrok:` before every `addElements:withTexture:`. But the upper part no longer shows anything. In fact, I have called `finishCurrentStroke:` in the `didEndStrokeWithCoalescedTouch:` delegate to make the...

another problem : There are some elements that will not be added to the upper part by `addElements:withTexture:`. Usually the last few elements of a stroke and especially when I...

adam, help!!!

I ran the demo and did two things. 1. present ViewController (JotView inside), then dismiss it 2. Repeat the first step the dealloc method has not been executed and the...
