# TPrinterCanvas.LeftMargin

The size of the margin at the left edge of the canvas.

## Declaration

Source position: printers.pas line 130

`public property TPrinterCanvas.LeftMargin : Integer read GetLeftMargin write FLeftMargin;`

## Description

LeftMargin is an Integer property which contains the size for the area between the edge of the paper and the left edge of the content on the page. Margin values are expressed as the number of "Dots" for the native printer resolution (XDPI). To achieve a .5in margin on a 300DPI laser printer, use the value 150.

The value for the property is normally provided by the Printer using the canvas to render document pages. When the property contains 0 (zero) and the Printer is assigned, its PaperRect property is examined to get the Left of the printable area for the paper size. Otherwise, the existing value in the property is used.

Changes to the property value are not applied to the Printer device.

Use RightMargin for the unused area at the right edge of the canvas. Values in LeftMargin, RightMargin, and PaperWidth are used to calculate the PageWidth for the printer canvas.
