Example 41 with ImageWriteParam

use of javax.imageio.ImageWriteParam in project jdk8u_jdk by JetBrains.

the class DisableCompressionTest method testFormat.

        param.setCompressionMode(mode);
        // now we are trying to disable compression.
        // This operation is not supported because GIF image writer
        // does not provide uncompressed output.

        // will be thrown here and current compression mode will not be
        // changed.
