er.attachment.thumbnail
Class ImageIOImageProcessor

java.lang.Object
  er.attachment.thumbnail.ERImageProcessor
      er.attachment.thumbnail.ImageIOImageProcessor

All Implemented Interfaces:

IERImageProcessor

public class ImageIOImageProcessor
extends ERImageProcessor

ImageIOImageProcessor is an implementation of the IImageProcessor interface on top of Mac OS X's ImageIO and CoreImage libraries. This is, by far, the fastest implementation of image processing provided. To use this implementation, you must build the native ImageIOImageProcessor.jnilib provided in the Native/MacOSX/ImageIOImageProcessor xcode project and place the library in your JNI library path (for example, /Library/Java/Extensions).

Description copied from interface: IERImageProcessor

Processes the given image with all of the given configuration settings. Order: resize/dpi, colorspace, crop, sharpen, gamma, watermark

Parameters:

resizeWidth - the maximum width to resize to (or -1 to not specify)

resizeHeight - the maximum height to resize to (or -1 to not specify)

resizeQuality - influences the resize algorithm to use (or null to not specify)

dpi - the dpi to resize to (or -1 to skip)

sharpenRadius - the radius of the unsharp mask (or <= 0.0 to skip)

sharpenIntensity - the intensity of the unsharp mask (or <= 0.0 to skip)

gamma - the gamma to apply (or 0.0 to skip)

cropX - the x position of the crop (or <= 0 to skip)

cropY - the y position of the crop (or <= 0 to skip)

cropWidth - the width of the crop (or <= 0 to skip)

cropHeight - the height of the crop (or <= 0 to skip)

watermarkFile - the watermark File to apply to this image (or null to skip)

tileWatermark - whether or not to tile the watermark

compressionQuality - the compression quality of the resize to perform (0.0 to ignore) -- range is 0.0 to 1.0 (1.0 = best)

colorProfileFile - the ICC profile to use (or null to skip)

inputFile - the File to perform the given operations on

outputFile - the File to write the resulting output image to

outputMimeType - the desired mime type of the output file

Throws:

java.io.IOException - if the image processing fails
