imageWithData:scale:

Declaration

+ (UIImage *) imageWithData:(NSData *) data scale:(CGFloat) scale;

Parameters

• data:

  The image data. This can be data from a file or data you create programmatically.

• scale:

  The scale factor to use when interpreting the image data. Specifying a scale factor of 1.0 results in an image whose size matches the pixel-based dimensions of the image. Applying a different scale factor changes the size of the image as reported by the Size property.

Return Value

A new image object for the specified data, or nil if the method could not initialize the image from the specified data.

Discussion

This method does not cache the image object.
