When saving files, inquire about picture compression functio

[SungwonShin]

Hi, I am Sungwon.

When you click 'File' -> 'Save As' on PowerPoint and select a folder, a window that specifies the file name and format pops up. If you click "Tools" at the bottom right of the window, there is a "Picture Compression" menu at the bottom, where you can reduce the total file size by compressing the picture size.

Is there a method for picture compression among the methods of 'Spire Presentation for Java'?

Hello,

Thanks for your inquiry.
Sorry, our product does not support compressing images in documents when saving them. As a solution, you can extract the images from the document and compress them using Java's built-in image processing library (such as javax.imageio) or other third-party libraries, and then replace the original images with the compressed images. Please refer to the following tutorials for extracting and replacing images. If you have any questions, please feel free to contact us.
