QT, fast!! pixel (color) mixing

Posted 06-21-2013 at 09:22 AM by rainbowsally
Updated 06-21-2013 at 09:32 AM by rainbowsally

Today's feature
  • super fast color mixing ('lerp') for QT4
  • PRINT_AND_DO macro to show function and execute it.
  • 8 bit fixed point math.
  • A snippet of working code from the next lq-qt/mc2 lib.

Behind the scenes we are working on getting qwt lib to play nice with Designer. We're apparently over the hump with dials, which were very tricky!!

And so it's break time.

Let's talk a bit about fast color mixing, which isn't always an issue but can be when you are...

Finished coding my Python login system

Posted 06-21-2013 at 07:19 AM by Pyplate

I've more or less finished coding the login system for my CMS. Now I just need to configure Apache to use SSL for the Admin area. Once I've done that, I can focus on the back end. I've built a page that allows you to edit posts, but it's very basic at the moment. I also need to create a page where users can edit site settings, and I need to make a page where users can list pages and categories. I've got a lot to do, but I'm making good progress.

Traffic to my Raspberry Pi web site...

This in That. Using the arduino with the rs232 daughterboard

Posted 06-20-2013 at 01:46 PM by peonuser

Using the Arduino for proects. simplest lately was to project a simple web page so that I could take down the internal web server without the users not knowing what was going on. Sort of an under construction page is delivered. Next project is to interface an old composite monitor and use it for displaying messages that can be updated via ethernet remotely.

Installed adosbox on the Nexus 7. Running a lot of my old qbasic programs such as a spreadsheet on it. Not gui, but sure is practical...

[Update: June 20, 2013 - corrected name in lqToPixel.]

Progress report.

We found a bug in the incremental backup program uploaded recently.

[Update June 24, 2013, see Gazi's bug fix below and here's a version that uses C/C++ to do it from a compiled executable.
