After I modified my code, it runs smoothly

BufferedImage image = sheet.toImage(sheet.getFirstRow(), sheet.getFirstColumn(), sheet.getLastRow(), sheet.getLastColumn());
File file = new File(FILE_PATH + fileName + FILE_TYPE);
ImageIO.write(image,"png",file);

Hello,

Thank you for your inquiry.
I used the latest Spire.XLS (Spire.XLS for Java Version:4.5.3) to test the code you provided (sheet.saveToImage(path)) on Linux, but did not replicate your issue. If you were not using the latest version, we recommend you give it a try firstly. If the problem still exists, please provide your complete test code and your input excel file. You could attach them here or send to us via email (support@e-iceblue.com). Thanks in advance.
Sincerely,
