Stack Blur implementation for iOS

stackblurios's Issues

Images downloaded using SDWebImage got blue shade.

Thanks for your work.

This works perfect when we use this with the locally stored image. I was trying to use this with the SDWebImage completion blocks where we set the image to the imageView after the image is downloaded from URL but the blur adds some blue shades all over the image if we use the image downloaded using SDWebImage

Any one faced this issue? Need help!

Thanks.

Update:

i managed to fix this issue by converting the downloaded image with UIImageJPEGRepresentation.

UIImage *processedImage = [[UIImage imageWithData:UIImageJPEGRepresentation(downloadedImage, 1)] stackBlur:10]
imageVIew.image = processedImage

vertical offset problem

fbc.blurredImage = [[self screenShot:self.view] stackBlur:8];
//fbc.blurredImage = [self screenShot:self.view];

For a large UIImage (screenshot) it seems like stackBlur offsets the original image vertically by something like 25 pixels.
If I comment out the first line and uncomment the 2nd one, I see the original, non-offset Image.
Otherwise the first 20-30 scan lines are not blurred, then followed by the same 20-30 scan lines but now blurred.

Static analyzer reports leak, logic errors

The Xcode 4.6.2 static analyzer reports (correctly as far as I can see) that the object returned by CGDataProviderCopyData() is leaked.

It also reports two logic errors, which might be false positives. In any case it'd be nice to quiet the warnings.

Clarify the license

This looks really useful! I'd love to use it in my project but the license isn't specified, which makes it impossible to use in shipping code. Would you consider opening it up with a BSD or Apache license? Thanks for your consideration.

Memory leak repeat

Implicit conversion warning

Hi,

First thanks for such class. In XCode 5.1.1 this warning appears 👍

UIImage+StackBlur.m:319:58: Implicit conversion from enumeration type 'enum CGImageAlphaInfo' to different enumeration type 'CGBitmapInfo' (aka 'enum CGBitmapInfo')

Best Regards

Assigned value is garbage or undefined in UIImage+StackBlur

Has anyone noticed following warnings while Analysing code? I have tried fixing by initialising values for rsum or dv but not able to resolve them. Has anyone fixed them?

...StackBlur/UIImage+StackBlur.m:155:4: Assigned value is garbage or undefined
...StackBlur/UIImage+StackBlur.m:244:4: Assigned value is garbage or undefined

Thanks.

When running on Retina the image dimensions get messed up

I'm not quite sure what's happening but my image which is 320x320 becomes 320x640 after running

UIImage *newIma=[oldIma stackBlur:radius];

Any ideas?

Memory leak in UIImage+StackBlur.m

i found memory leak in UIImage+StackBlur.m stackBlur: method.

check this:
CFMutableDataRef m_DataRef = CFDataCreateMutableCopy(0, 0, CGDataProviderCopyData(CGImageGetDataProvider(inImage)));

CGDataProviderCopyData copy data but not release.

How to revert blur effect

When I tried to normalize an @2x image (for retina display) it returns a LowQuality image. I use normalize to revert the blur effect, but anyway, If I don't use normalize, the image looks like reversed color. How can we solve this issue?
