Hello: I am still hoping for some insight.
What does it take to efficiently draw a good looking, anti-aliased line? Do I have to buy in to the use of OpenGL? I am just drawing lines. Thanks. Bill (The man who *is* who he appears to be. Apparently that is not as easy as you might think.) On 03/16/2017 08:15 AM, william.croc...@analog.com wrote:

Learn about spoofing at http://aka.ms/LearnAboutSpoofing] Hello: I am slowly porting my app forward from Qt 4.8.6 With 4.8.6, it is my observation that simple line drawings, as made by a QPainter and with Antialiasing enabled in render hints, are implemented in software which makes them quite slow. What can I look forward to if I port my app to 5.X (5.7) Is there an option for hardware acceleration of AA line drawing and how would I enable it. I develop on RedHat Enterprise Linux 6.8 Thanks.
