FWImageResponseSerializer
@interface FWImageResponseSerializer : FWHTTPResponseSerializer
FWImageResponseSerializer
is a subclass of FWHTTPResponseSerializer
that validates and decodes image responses.
By default, FWImageResponseSerializer
accepts the following MIME types, which correspond to the image formats supported by UIImage or NSImage:
application/octet-stream
image/tiff
image/jpeg
image/gif
image/png
image/ico
image/x-icon
image/bmp
image/x-bmp
image/x-xbitmap
image/x-ms-bmp
image/x-win-bitmap
image/heic
image/heif
image/webp
image/svg+xml
-
The scale factor used when interpreting the image data to construct
responseImage
. 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. This is set to the value of scale of the main screen by default, which automatically scales images for retina displays, for instance.Declaration
Objective-C
@property (nonatomic) CGFloat imageScale;
-
Whether to automatically inflate response image data for compressed formats (such as PNG or JPEG). Enabling this can significantly improve drawing performance on iOS when used with
setCompletionBlockWithSuccess:failure:
, as it allows a bitmap representation to be constructed in the background rather than on the main thread.YES
