List of encodeImage() Examples

Examples of encodeImage()

hipi.image.io.ImageEncoder.encodeImage()
org.apache.myfaces.trinidadinternal.image.encode.ImageEncoder.encodeImage()
Encodes the image to the specified output stream.
=-=ags Should probably throw something in addition to IOException to handle other problems @param image The image to encode @param out The output stream to which the image should be encoded
org.pentaho.reporting.libraries.base.encoder.ImageEncoder.encodeImage()
Encodes the given image using the given encoder-specific quality and alpha-channel settings and writes the encoded image-data to the given stream. @param image the image to be encoded. @param outputStream the output stream, where to write the image data to. @param quality the quality of the encoding. @param encodeAlpha a flag controlling whether the alpha-channel should be encoded as well. @throws IOException if there was an IO error while generating or writing the image data. @throws UnsupportedEncoderException if the encoder is not supported.
