Class PrintOutNet

This is the base class for all Report processing drivers working in Reportman.Drawing space, that is print to printer, preview on screen or exporting to bitmap, provides basic functionality to measure texts, bitmaps and shapes, but still not work with printers (System.Drawing.Printing) or printer dialogs (Windows Forms). So it's a step forward to the implementation of some Report processing drivers, useful for preview, becuase it can use bitmap as output Variant

Syntax

public class PrintOutNet : PrintOut, IDisposable

Constructors

PrintOutNet()

Constructor and initialization of graphics objects required for the driver

Declaration

public PrintOutNet()

Fields

HardMarginX

This variables can be used as an offset, this is used by print preview to represent the non-printable area of the page

Declaration

protected int HardMarginX

Field Value

Type	Description
int

HardMarginY

This variables can be used as an offset, this is used by print preview to represent the non-printable area of the page

Declaration

Output

The output in this driver is a bitmap, the output can be used to preview or convert it to serve in a web application

Declaration

public Bitmap Output

Field Value

Type	Description
Bitmap

Scale

This property allows scaling, usefull for drawing a preview inside a sized bitmap

Declaration

public float Scale

UseHardMargin

Because HardMargins are non-printable area, when printing to the device with this limitation, the offsets must be disabled

Declaration

protected bool UseHardMargin

Field Value

Type	Description
bool
