Next is the actual processing. IexReadImageToScratchPad first call support function for the image from the BLOB locator, data structures needed to construct ImageMagick, and a pointer to point to the data structure on the scratchpad. If not the first time this function, you can reuse the last allocated data structures. Rotation itself is to use ImageMagick function RotateImage. The results were again placed in ImageMagick-specific data structure, this structure needs to be converted into a BLOB, and passed through a locator DB2. This is done by using the support function IexWriteImageToLocator to complete. Listing 1. UDF image rotation on the sample code / ** Rotate the image. * The given image is rotated using the ImageMagick function RotateImage. * The angle needs to be specified in degrees. The angle is taken modulo 360 * degrees; in other words, angles larger than +360 degrees and smaller than
Firewall and VPN is a compute-intensive applications that require high bandwidth and throughput. Therefore, they may become the bottleneck of network performance. Alteon Web switches used to deploy firewall and VPN load-balancing feature can easily solve this problem. Alteon Web switches can be used in a number of comprehensive distribution of business between devices so that multiple firewall / VPN to run. Using Layer 2 to Layer 7 information, Alteon Web switches can correctly determine how to send business to achieve high security, security extensions can be achieved, while also providing redundancy and failover capabilities.
