TIFF conversion is broken

[tmhung88]

I ran several examples of Excel-TIFF conversion and all outputs were corrupted.

OS: Mac Catalina 10.15.3 JDK: OpenJDK 11.0.1

@tmhung88 ,

You need to download JAI libraries and add them to classpath/project. Please note, to convert spreadsheet to TIFF image(s) you should have JAI libraries to be set in your classpath or project.

If you still find the issue (after installing JAI libraries), please share your sample code (runnable) with sample source files, we will check it soon.

@amjad-sahi I'd like to point out that this repo does include JAI library https://github.com/aspose-cells/Aspose.Cells-for-Java/tree/master/Examples/libs. However, there are missing other JAI packages that are required for color processing. I hope that we include complete JAI packages into the example so that people don't have to look around for them.
