要在Mac OS X中使用Cocoa或C++截取屏幕截图,您可以使用以下方法:
在Mac OS X中,您可以使用Cocoa框架轻松截取屏幕截图。以下是一个简单的示例代码:
#import <Cocoa/Cocoa.h>
@interface AppDelegate : NSObject <NSApplicationDelegate>
@property (nonatomic, strong) NSScreen *screen;
@end
@implementation AppDelegate
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
// Insert code here to initialize your application
self.screen = [NSScreen mainScreen];
[self captureScreen];
}
- (void)captureScreen {
NSRect screenRect = [self.screen frame];
NSBitmapImageRep *bitmap = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:nil
pixelsWide:screenRect.size.width
pixelsHigh:screenRect.size.height
bitsPerSample:8
samplesPerPixel:4
hasAlpha:YES
isPlanar:NO
colorSpaceName:NSDeviceRGBColorSpace
bytesPerRow:0
bitsPerPixel:0];
NSGraphicsContext *context = [NSGraphicsContext graphicsContextWithBitmapImageRep:bitmap];
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:context];
[self.screen.window.contentView display];
[NSGraphicsContext restoreGraphicsState];
NSBitmapImageRep *imageRep = [bitmap copy];
NSImage *image = [[NSImage alloc] initWithSize:screenRect.size];
[image addRepresentation:imageRep];
NSData *imageData = [image TIFFRepresentation];
NSError *error;
NSURL *fileURL = [NSURL fileURLWithPath:@"/Users/username/Desktop/screenshot.png"];
[imageData writeToURL:fileURL options:NSDataWritingAtomic error:&error];
}
@end
如果您想使用C++截取屏幕截图,您可以使用以下方法:
