This example describes how Python converts raw pictures into PNG pictures through the PIL module. Share to everyone for your reference.

I. Overview The application of GDI + makes the graphic image programming easier, this paper takes a dialog-based clock program as an example, calls the *.png picture to implement the translucent gradient window in the VC6.0, the program realizes both the pointer and the digital clock display mode. The window implements a semitransparent gradient window, drag the window without moving the rectangle, hide the Taskbar form button, and so on. The effect

process of daily communication refers to the resolution generally refers to its width and height of the number of pixels. Second, the picture on the hard disk Pictures are a waste of space if they are stored in the same way as memory. For example, if a picture is all red, it is necessary to store each pixel point. It only needs to record its red and size just fine, in memory can be re-restored. The picture is generally compressed during transmission and storage. 1.

Due to project needs, our WPFProgramNeed to run on the terminal, Running platform: Windows XP embedded Hardware: Atom, 2 GB memory, gma950, During the test, we found that the entire program was running very slowly. Because we used multiple threads, we initially suspected it was caused by thread switching. Using processexplorer to view the process, unexpectedly, we found that the CPU is mostly consumed on rendering. In addition, it is important to note that the CPU usage is kernel-mode.Code.
