Chart.ToImage(...) returns "java.lang.Exception: Image format(TIFF) is not supported." error

Hello,
we have found a problem, using Aspose Cells version 24.1, when we try to save a chart as image, using Chart.toImage(OutputStream stream, ImageOrPrintOptions options).

The error is:
java.lang.Exception: Image format(TIFF) is not supported.

If we create ImageOrPrintOptions as follow

ImageOrPrintOptions opts = new ImageOrPrintOptions();
opts.setOnePagePerSheet(true);
opts.setOnlyArea(true);
opts.setChartImageType(ImageFormat.getTiff());
opts.setHorizontalResolution(150);
opts.setVerticalResolution(150);

there are no problem, but using

ImageOrPrintOptions opts = new ImageOrPrintOptions();
opts.setImageType(ImageType.TIFF);
opts.setOnePagePerSheet(true);
opts.setOnlyArea(true);
opts.setHorizontalResolution(150);
opts.setVerticalResolution(150);

the problem occurs.

This property “opts.setChartImageType(ImageFormat.getTiff());” is deprecated but into the documentation there is not written what we can use in the place of it.

We attach a test that reproduce the problem.

Could you help us to understand how we can solve the problem, please?
Thanks,
Giulio

Thanks for the template Excel file and details.

After initial test, I was able to reproduce the issue as you mentioned by using your template Excel file and sample code. I found that Chart.toImage(…) returns “java.lang.Exception: Image format(TIFF) is not supported” error. It works fine for other image formats though.
