Pixelization & Anti-aliasing Issue

Solar2D Advanced Graphics
#1

Hi guys,

I am trying to draw some angled-lines (using newLine & newPolygon), but I notice the lines are pixelized.

I set the ‘antialias = true’ in config.lua, but it still persist.

Any advise on how to make it a nice line ?

What about adding a filter to them? Like blur and then sharpen? Not sure if you can do that.

Don’t know if it would work with lines but you might want to take a look at ingemar’s idea in this thread

It’s about making antialias on polygons by using small images as stroke fills.

We turned off anti-aliasing a long time ago for performance reasons (back when Graphics 2.0 came out) if I’m remembering correctly. I’ll ping the engineers and see if they remember why.

Thanks guys. I tried drawing the line with an image file ( 2px width, 1px height). but still having the problem. Will have wait for the anti-aliasing feature.

local function testLineImage( xPos, yPos ) local line1 = display.newImageRect( 'asset/line\_v1.png', 2,1 ) line1.xScale = 50 line1.x = xPos + line1.contentWidth/2 line1.y = yPos line1:rotate( math.random( 0,90) ) return line1 end
