In the last lecture, we mainly describe the access, image display of the BMP image data, and the operation of the color palette. On the basis of the above study, we can further deepen, learn and master image special effects display technology. With this technology, you can use the future project development to beautify our software interface and improve the visual effect of software. In today's commercial software, almost every image is displayed, such as the reader's more familiar Windows screen saver uses a variety of image special effects display, making people dazzling and refreshing. Professional image processing software is a rich display method for users to use, which can be easily displayed in programs, such as Photoshop, Authorware, etc. This section mainly describes how to achieve image relief, engraving, multi-page windows, rotation, scanning, grid, mosaic, and gradual implications. Through this lecture study, readers can also work hard to make software with special effects showing effect.
