Parameters

Return Values

N/A.

Remarks

Note 1: Coordinate system information:

  1. The unit size is point. 1 point = 1/72 inch (1 inch = 72 points). 1 inch = 2.54 cm = 25.4 mm.
  2. The location of the origin (0, 0) is at top-left corner.
  3. To get page size information from a PDF file, use GetPageSize method.
    The page number uses zero-based index, meaning that page numbering starts from 0.

Note 2: OLE_COLOR conversion from various programming languages:

C++:

static_cast<OLE_COLOR>(RGB(0, 0, 255))

VB6:

RGB(0, 0, 255)

VB.NET:

Convert.ToUInt32(System.Drawing.ColorTranslator.ToOle(Color.FromArgb(0, 0, 255))

C#:

(uint)System.Drawing.ColorTranslator.ToOle(Color.FromArgb(0, 0, 255))

Others:

32 bit integer value in following format: 0x00bbggrr (in BGR format, not in RGB)

For more information about color translation, refer to MSDN Knowledge Base article Q131101.
