{Copyright Alan Chamberlain 2021
This unit renders the text and image components of a form to a PDF using the
fcl-pdf package. The object is not to provide a pixel by pixel representation of
the form, but to record the text and image information. Multiline controls such
as TStringGrid and TMemo are printed out in their entirety. the unit is
modularised so new components can be added easily. Supported components are:
TForm
TLabel
TStaticText
TEdit
TSpinEdit
TFloatSpinEdit
TSpinEditEx
TFloatSpinEditEx
TDirectoryEdit
TFileNameEdit
TComboBox
TListBox
TStringGrid
TValueListEditor
TMemo (does not support word wrapping)
TCheckBox
TRadioButton
TImage
TChart
TShape (rectangle, rounded rect, ellipse)
TPageControl
TTabSheet
TGroupBox
TPanel
TRadioGroup
TCheckGroup
TScrollbox
To use copy form2pdf.pas into your source directory and include Form2PDF in
your uses clause. Any visual control can be passed as a parent eg. TTabControl.
