One thing to try is to use a larger step width for your pen. The default Pen.m uses a step width of .5, but increasing that to 2 or 3...

The JotStrokeManager.m needs to have its compiler flags set to `-fno-objc-arc`. To do that, go to project settings, Build Phases, and add that flag to the JotStrokeManager.m in the source...

The blur doesn't seem to be because of the zoom, it looks like it's from the brush texture. you can see in A that the edges have that same lightness...

Since JotView rasterizes what's written, some amount of blur will be expected. You can see some blurring in Loose Leaf as well if you pinch to zoom a page, it'll...

JotView will export a transparent image with only strokes by default. are you loading in an opaque image before drawing by chance?

I just tested the jotuiexample and it is indeed saving a transparent image with only ink visible. how are you saving and loading the image to see if it's transparent...

ah that would do it :) glad its an easy fix

instead of a raster based view like JotUI, you'd need a vector based view. One strategy i've seen show smooth results at any zoom was for each stroke to use...

the problem isn't open gl, it's that it's rasterized at all. the zoom is being done by scaling the view itself, which will blur the rasterized content. that's why CALayers...

I can't think of anything offhand that would cause that. I suggest stepping through `renderAllStrokesToContext` and making sure all strokes/elements are in fact getting drawn. Also check that it's not...
