TMS FNC Printing
The print library supports creating documents,
adding pages and page content such as HTML formatted text, plain text, drawing
primitives and images, with practically the same code on all different frameworks.
This has been implemented on three different levels.
The lowest level of implementation for the print library is the use of TMSFNCPrinter, this is done in a similar way as TPrinter is used on VCL, Lazarus, FMX Windows and MacOS. With TMSFNCPrinter there is now support for FMX Android and iOS and for TMS WEB Core.
The difference with TPrinter is that the drawing should be defined in the OnDrawContent procedure.
uses , FMX.TMSFNCPrinters, FMX.TMSFNCGraphicsTypes; procedure Click(Sender:TObject); begin TMSFNCPrinter.OnDrawContent := procedure begin TMSFNCPrinter.Graphics.Font.Color := gcBlue; TMSFNCPrinter.Graphics.Font.Size := 40; TMSFNCPrinter.Graphics.DrawText(0, 20, TMSFNCPrinter.PageWidth, 100, 'Hello', False, gtaCenter, gtaCenter); TMSFNCPrinter.Graphics.Fill.Color := gcRed; TMSFNCPrinter.Graphics.DrawEllipse(100,200, TMSFNCPrinter.PageWidth - 100, 300); TMSFNCPrinter.Graphics.DrawBitmap(50,400,TMSFNCPrinter.PageWidth - 50, TMSFNCPrinter.PageHeight - 50, Image1.Bitmap, True, True); TMSFNCPrinter.EndDoc; end; TMSFNCPrinter.BeginDoc; end;
On top of the TMSFNCPrinter, there is the TMSFNCGraphicsPrintIO component, which gives the ability to further define the layout of the document with a header, footer and page number and to add certain FNC components.
The TTMSFNCRichEditorPrintIO and TTMSFNCGridPrintIO are added In the TMS FNC UI Pack. These components have some additional properties to make the export of the TTMSFNCRichEditor or TTMSFNCGrid even more customizable.
Working with FNC controls should be fast and simple. And for that reason we're adding two new design-time editors in TMS FNC Core.
These help with setting the properties for the TTMSFNCGraphicsFill and TTMSFNCGraphicsStroke.
