The 15 components registered on the sgcPDF palette page: 14 in the VCL design time package and TsgcPDFViewerFMX in the FireMonkey one. The non visual components can also be created in code from console applications, services and servers.

|---|---|---|---|
TsgcPDFDocument | sgcPDF_Document | VCL, FMX, console, service | Creates, loads, edits and saves PDF documents: pages, text, TrueType and OpenType fonts, images, vector graphics, tables, barcodes, annotations, bookmarks, layers, forms, attachments, encryption and PDF/A. |

TsgcPDFOutlineView | sgcPDF_ViewerVCL | VCL (Windows) | Bookmarks (outline) tree linked to a TsgcPDFViewerControl. |
TsgcPDFViewerFMX | sgcPDF_ViewerFMX | FMX: Windows, macOS, iOS, Android | FireMonkey PDF viewer control drawing through the FMX canvas, with scroll, zoom and page navigation. |
Beyond the palette, the units expose classes you create in code, such as TsgcPDFParser, TsgcPDFRendererRaster, TsgcPDFAValidator, TsgcPDFCanvas and the TsgcPDFPAdESSigner bridge to sgcSign. See the feature matrix for what each area covers.
