First, in the development of iOS, to the image gray this function is often used, such as product display, the product expired or offline, then the image needs this function. The following method can be used to achieve the purpose./** UIImage: The implementation of the color function (picture gray display) @param sourceimage pictures*/-(UIImage *) Grayimage: (UIImage *) sourceimage{intBitmapinfo =Kcgimagealphanone; intwidth =SourceImage.size.width; intHeight =SourceImage.size.height; Cgcolorspace

Iv. Optical Drive Glossary
CLV technology: (Constant-Linear-Velocity) Constant line speed reading method. The technology used in an optical drive that is less than 12 times faster. It is used to change the speed of the rotating disc at any time to keep the data transfer rate unchanged. The speed of reading data along the internal direction is much faster than that of the external side.
CAV technology: (Constant-Angular-Velocity) Constant Angular speed reading method. It reads data on the
, manually add the optical drive accelerator program or other programs found from the network or the disc. The drive of the optical drive is usually included in WIN98 and 95, and does not need to be added. In security mode, you can delete the CDROM option in Device Manager and restart the computer so that the system can find the new hardware and reinstall the drive of the optical drive.
