Package com.cloudinary.android.preprocess

Class ImagePreprocessChain

  • public class ImagePreprocessChain
extends com.cloudinary.android.preprocess.PreprocessChain<android.graphics.Bitmap>
    A preprocess chain to run on images before uploading. Pass an instance of a populated chain to UploadRequest.preprocess(PreprocessChain). The processing steps will run by the order in which they were added to the chain. This chain uses the default Bitmap encoder/decoder, however custom implementations can be supplied using PreprocessChain.loadWith(ResourceDecoder) and PreprocessChain.saveWith(ResourceEncoder).

      • limitDimensionsChain

        public static ImagePreprocessChain limitDimensionsChain​(int maxWidth,
                                                        int maxHeight)
        Convenience method for building an efficient dimension limiting chain using BitmapDecoder and Limit. Use this in UploadRequest.preprocess(PreprocessChain). The scaling retains the original aspect ratio while guaranteeing the height and width are within the requested maximum bounds. Note: If the image is already smaller it will be returned unchanged.
        Parameters:
        maxWidth - The maximum width allowed. If the width of the image is greater, the image will be resized accordingly.
        maxHeight - The maximum height allowed. If the height of the image is greater, the image will be resized accordingly.
        Returns:
        The prepared chain to pass on to UploadRequest.preprocess(PreprocessChain)
