Example 1 with VideoMediaSampleJPEG

use of cbit.vcell.export.gloworm.quicktime.VideoMediaSampleJPEG in project vcell by virtualcell.

the class FormatSpecificSpecs method encodeJPEG.

    ImageWriteParam imageWriteParam = imageWriter.getDefaultWriteParam();
    imageWriteParam.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
    // quality 0(very compressed, lossy) -> 1.0(less compressed,loss-less)
    imageWriteParam.setCompressionQuality(compressionQuality);
    IIOImage iioImage = new IIOImage(bufferedImage, null, null);
