Description

When using the Scalable 2D Vector Graphics API, the method ScalableGraphics.render() may cause some artifacts when it renders on top of some other image and transparency is used. The artifacts appear as horizontal black lines when rendering rather complex graphics.

How to reproduce

This issue affects JSR-226 when running on the emulator.

The issue can be reproduced with the following code snippet:

  ScalableGraphics.bindTarget();
ScalableGraphics.setTransparency( 1f );
ScalableGraphics.render( 0, 0, svgImage );
ScalableGraphics.setTransparency( 0.5f );
ScalableGraphics.render( 50, 50, svgImage );
ScalableGraphics.releaseTarget();

Solution

This issue is fixed in S60 3rd Edition, FP2 MIDP SDK.
