PDF Stamp in wrong position with small files

Aspose.PDF Product Family

Hi,

Issue we have encountered while using Aspose for updating stamps in PDF documents. While providing the correct coordinates for the stamp position, we have noticed that the stamp’s placement is inconsistent across different documents. In some cases, the stamp appears in the correct position, aligning horizontally as expected. However, in other documents, we have observed that the stamp is displayed vertically, which is not the intended behavior.

Please let us know if there are any specific settings or configurations that need to be adjusted or if there are any known issues with stamp positioning in Aspose.

Thanks.

It is quite possible that pages are rotated in the PDFs where stamps are not being displayed on correct positions. Therefore, you can set Rotation property to none and add stamps to render them on correct positions. Rotation can be applied again after adding stamp.

Regarding the rotation of the pages, I have checked and there are no issues with it. The document where the stamp is incorrectly placed has the same rotation as the document where the stamp is correctly placed. However, the stamp update is still incorrect.

document get rotated when set Rotation property to none but now we need to add the stamp in the certain rotation angle of the PDF.
