Problems solved by technology

[0004] SetLayeredWindowAttributes is suitable for creating a special-shaped window with a relatively simple appearance and no gradient effect. It has the following disadvantages: when it is necessary to generate an irregular-shaped special-shaped window, there must be a color for identifying the color (indicating that the area where the color is located in the special-shaped window is changed to fully transparent), so the color performance of the special-shaped window is limited; the pixel points of the special-shaped window can only have three alpha values ​​at most, and the gradient effect of transparency (such as shadow) cannot be realized, which leads to the limited expression of the special-shaped window; when it is necessary to output extremely complex shapes When using a window (such as directly outputting text), the edge aliasing is very obvious, and the performance is poor
However, this method has the following disadvantages: the number of acquired bitmaps is limited, and the interaction form is single, which is

Abstract

The embodiment of the invention provides a method and device used for generating a special-shaped window. The method includes the steps of packaging and initializing a Chromium embedded type frame, establishing an initial window, establishing an off-screen rendering browser through the Chromium embedded type frame on the basis of the initial window, generating bitmap data by loading page content data through the off-screen rendering browser, converting the bitmap data into an internal storage bitmap, and generating and outputting the special-shaped window through the UpdateLayeredWindow on the basis of the internal storage bitmap.

Description

technical field [0001] Embodiments of the present invention relate to the field of computers, and more specifically, embodiments of the present invention relate to methods and devices for generating special-shaped windows. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The operating system of the currently used electronic equipment is usually installed with a special-shaped window application, which can be customized by the user such as the shape, color, transparency and other properties of the window, such as media player, clock, anti-virus software icon and so on. Such special-shaped window applications are usually based on a layered window (Layered windows) technology to create special-shaped windows. The main features of the layered window technology include: allow...
