In our app we create a UIImage and set its scale. It is then saved to a jpeg using UIImageJPEGRepresentation(image, 0.8);
I am converting the app to 64-bit and the generated image has junk in the ppi block of the resulting jpeg. Below are examples of the data (output using ImageMagick identify) from an iPad Air 2 (I see similar behavior in the Simulator comparing the results from iPad Retina & iPad Air) 32-bit build: Format: JPEG (Joint Photographic Experts Group JFIF format) Mime type: image/jpeg Class: DirectClass Geometry: 2048x1536+0+0 Resolution: 376.736x376.736 Print size: 5.43617x4.07713 Units: PixelsPerInch 64-bit build: Format: JPEG (Joint Photographic Experts Group JFIF format) Mime type: image/jpeg Class: DirectClass Geometry: 2048x1536+0+0 Resolution: -1x-1 Print size: -2048x-1536 Units: PixelsPerInch Any suggestions appreciated for workarounds/solutions.
