In one of my previous posts, WPF vs. GDI+ I wrote about the performance of WPF and how to solve this problem. After some experiments in Kvinivel we've found more improvements to the solution described in the previous post. The main idea is that when you are converting GDI bitmap to WPF bitmap it requires memory allocation and decreases performance. And fortunately, there is a solution that allows mapping WPF bitmap to GDI bitmap, so when we are drawing on…

The problem In one of our projects in Kvinivel we need to draw a huge table of results of some physical experiments. The table can be 100x100 and can be 1000x1000. The application is usually Windows desktop application built with WPF. And as usual, we've tried to use some 3rd party grid. And as you can imagine, we've got unacceptable performance even with visualization. The most problematic thing is that the user needs to zoom out the table to see…
