Image file markup position does not match between web and mobile

how can i fix the mark position of image file on mobile (( Flutter )) to match the web?
(create markup on web )

The markup position of the pdf file is correct.

But the markup position of the image file is incorrect.

Hi there,

By default our SDK’s should handle images correctly, if you have made any changes to the process on your end then this may have some unexpected results.
Could you let us know if you are using PageSizes in your WebViewer ?
If so removing this may resolve your issue.

Best Regards,
