Hi,
Thanks for the template file and sample code.
After an initial test, I observed the issue as you mentioned. I found that rendering shapes in the spreadsheet give blank images, it looks like these shapes are not supported or there might be some other issue. I used the following sample code with your template file:
e.g Sample code: Workbook wb = new Workbook(“C:/Shapes.xlsx”); ShapeCollection shapes = wb.getWorksheets().get(0).getShapes(); for (int i = 0; i < shapes.getCount(); i++) { shapes.get(i).toImage(i + “.png”, new ImageOrPrintOptions()); } All the images generated are blank. I have logged a ticket with an id “CELLSJAVA-41765” for your issue. We will look into it soon.
Once we have any update on it, we will let you know here.
Thank you.
