PDF Constructor utilizes an XML grammar that combines elements of XHTML, CSS, and SVG to generate PDF documents that can be single or multi-page, featuring both pre-existing and dynamically created raster, vector, and textual content. You can create print-ready PDFs that support CMYK and spot colors while allowing for precise specifications of bleed and trim. The software facilitates the use of various font types, including Type 1, TrueType, and OpenType, ensuring that fonts are always embedded and can be optionally subsetted. It also enables the production of documents suitable for the web or screen, complete with bookmarks, hyperlinks, interactive actions, and JavaScript functionality, as well as the ability to construct comprehensive Acrobat Forms on the fly. Users can incorporate JPEG and TIFF images, adjusting for any colorspace and resolution, while applying transformations to ensure the images integrate seamlessly into the layout. SVG graphics can be included directly or referenced, and you have the option to specify individual pages or entire PDF files as templates for adding new content. Additionally, paragraph and character styles informed by CSS2 can be utilized for creating flowable content, enhancing the overall design and structure of your documents. This versatile tool streamlines the PDF creation process, making it a valuable asset for designers and developers alike.
