disappearing dashes at low resolution #51
Description
After switching from diagrams-cairo, I've noticed some gaps in dashed circles, compare robx/puzzle-draw#32
The first two below are fine, then some dashes start disappearing in a way that seems wrong:
These were rendered by the following code:
dia :: Diagram B
dia = bgFrame 0.15 white $
circle 0.35 # lwG (1/40) # dashingG [1/20, 1/20] 0
sizeSpec :: Double -> SizeSpec V2 Double
sizeSpec w = mkSizeSpec2D (Just w) Nothing
main :: IO ()
main = do
renderRasterific "test-dashing-100.png" (sizeSpec 100) dia
renderRasterific "test-dashing-80.png" (sizeSpec 80) dia
renderRasterific "test-dashing-50.png" (sizeSpec 50) dia
renderRasterific "test-dashing-40.png" (sizeSpec 40) dia
