Hej,
I tried to apply the following CIFilter to a pdfview, webview and/or a
simple view. I don't get any compiling errors, but it just nothing
happens. Am I missing a certain initialization part?
#import <Quartz/Quartz.h>
#import <QuartzCore/CAAnimation.h>
#import <QuartzCore/CoreImage.h>
...
{
NSArray *filters = nil;
CIFilter *filter = [CIFilter filterWithName:@"CIPointillize"];
[filter setDefaults];
[filter setValue:[NSNumber numberWithFloat:4.0] forKey:@"inputRadius"];
filters = [NSArray arrayWithObject:filter];
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:1.5];
[[webView animator] setContentFilters:filters]; // (a)
[[pdfView animator] setContentFilters:filters]; // (b)
[[view animator] setContentFilters:filters]; // (c)
[NSAnimationContext endGrouping];
}
\\\Uwe
