This month’s release includes contains a massive 154 improvements to Aspose.Words, including several big performance boosts and interesting new features. The amount of memory required to render a document has been reduced by more than 20-30%. Rendering of images to PDF improved by approximately 25% when saving with JPEG compression. The size of images stored in PDF files generated by Aspose.Words has been reduced in many cases. Duplication of images could sometimes occur in some situations. This issue has been resolved and file size improved in these cases. In this release Aspose.Words introduces support for digitally signing DOC and DOCX documents. A digital signature adds an extra layer of protection to a document and ensures that the document content has not been tampered with. This feature adds an “invisible” signature to the document, which is not to be confused with a signature line which is a digital signature accompanied by a normally handwritten signature image. With this release Aspose.Words can now detect the compliance of a loaded OOXML document and resave the document using the correct compliance. This avoids the document being saved to the wrong specification and unexpected compatibility warnings.
