	We have requirement of exporting Diagram to Image file(jpeg,png and gif), However doing this cause out of memory exception. Reason could be image have high resolutions(22348x4282) pixels. I am using diagram.createImage( BufferedImage.TYPE_INT_RGB) method to create image and writing it using ImageIO.write api. Is there any better way to do the same to overcome out ot memory error while writing image in file?

	Is createImage itself throwing memory exception or ImageIO.write?

	ImageIO.write because if components are in good amount in diagram, then image size is more than 7 to 10 MB or so, and i could not find a way to create image with less resolution. So due to size of image, application crashes while using ImageIO.write.

	We don't plan writing low-level image encoding code at this time. Try splitting the produced image into smaller ones in memory, write them into separate files, and use external tool to glue them in a large file. E.g. try ImageMagick / JMagick - https://www.imagemagick.org/script/index.php https://www.imagemagick.org/discourse-server/viewtopic.php?t=11320 If you are on older Java version, you might also check if latest JRE9 is able to serialize larger images.
