Unit # get (CodecsDocumentImageInfo)
A CodecsRasterizeDocumentUnit enumeration member that specifies the unit for PageWidth and PageHeight. The default value is pixel
.
The logical width and height of the document is the original size before rasterization. LEADTOOLS usually returns the logical size in inches.
The PageWidth, PageHeight and Unit properties are only valid if the value of IsDocumentFile is true.
Possible values are:
Value | Description |
---|---|
CodecsRasterizeDocumentUnit.Pixel |
The page width and height are in pixels |
CodecsRasterizeDocumentUnit.Inch |
The page width and height are in inches |
CodecsRasterizeDocumentUnit.Millimeter |
The page width and height are in millimeters |
