Aspose.PDF for .NET provides advanced processing capabilities for form fields. With this one single product, you can get the ability to add form fields to a PDF and can programmatically rename, delete, and copy form fields throughout the PDF, apply JavaScript code to the Push button, and integrate the contents of the form fields into the document. This product is also good when it comes to setting field attributes such as READ_ONLY, REQUIRED, NO_EXPORT, HIDDEN, NOZOOM, and you can easily set visual attributes such as Alignment, BorderStyle, ButtonStyle, FontSize, TextColor, TextEncoding or independently determine where to place form fields in absolute coordinates for a document.
Import and export data from form fields in XML, FDF, or XFDF files, or combine form fields with OLEDB or ODBCDB data sources. You can also import images or barcodes, get data from fields and RTF formatting, or add a “Submit” button for the purpose of uploading data to a predefined URL.

You can also convert images contained on your disc or in memory or at an Internet address into PDF format. Along with conventional image formats, CCITT (fax) images, multi-page TIFF images, and transparent GIF images are also supported.

Create right-aligned paragraphs, save spaces in text, set custom paragraph indents, and define text formatting for all document segments.
Along with the ability to specify horizontal alignment for text, you can also specify vertical alignment for text segments, such as bottom or top alignment. Background and text colors can be changed, use replaceable characters that will allow you to change the associated text in real time.
