While profiling our reporting solution I noticed that a significant amount of time is "lost" in

com.sun.imageio.plugins.png.PNGImageWriter.write(IIOMetadata, IIOImage, ImageWriteParam)

which is called from

Code: Select all

com.steema.teechart.exports.ImageExportFormat.save(ImageOutputStream)

I was wondering whether the installation of JAI (Java Advanced Imaging) with its native libs would improve performance? Is TeeChart prepared to make use of JAI?

Cheers,

My findings:
- TeeChart has, as expected, no problem with JAI ImageIO
- since ImageExportFormat uses ImageIO.getImageWritersByFormatName(fileExtension) the JAI PNG writer is automatically picked up once JAI is installed
- even with the native libs the performance gain is minor (<1s)
