iframe 项目总结 how to use merge UIImage

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo{
//將ImagePicker取得的圖片指定給我們的ImageView
NSLog(@"===i am here ok le a /n");

mySaveImage=nil;
UIImage* bottomImage = image;
UIImage* topImage    = [Process_UIImage myImageNamed:frameName];

//放缩图像到指定尺寸

if(topImage.size.width>topImage.size.height)

[tp release];

bottomImage=[Process_UIImage rotate:bottomImage:-90];

topImage=[Process_UIImage imageRSize:topImage:CGSizeMake(FrameWidth,FrameHeigth)];
[tp release];
