PDFReaderInfoXY (Function)

In french: LecteurPDFInfoXY

For a given position in a PDF Reader control (coordinates of a control point), returns one of the following::

the page number for the specified position,
the X-position (in mm) for the specified position,
the Y-position (in mm) for the specified position.

Example

// Page number
nPage is int
nPage = PDFReaderInfoXY(PDF_NoName1, pdfPageNumber, MouseXPos(), MouseYPos())

// X-position in millimeters
rXPos is real
rXPos = PDFReaderInfoXY(PDF_NoName1, pdfXCoord, MouseXPos(), MouseYPos())

// Y-position in millimeters
rYPos is real
rYPos = PDFReaderInfoXY(PDF_NoName1, pdfYCoord, MouseXPos(), MouseYPos())

Syntax

<Result> = PDFReaderInfoXY(<PDF Reader control> , <Type of information> , <X> , <Y>)

<Result>: Real

Requested information.

<PDF Reader control>: Control name

Name of PDF Reader control to use.
If this parameter corresponds to an empty string (""), the control to which the current event belongs will be used.

<Type of information>: Integer constant

Requested type of information:
pdfXCoord X-coordinate of the specified position on the page (expressed in millimetres).
pdfYCoord Y-coordinate of the specified position on the page (expressed in millimetres).
pdfPageNumber Number of the page that contains the specified position.
pdfOriginScreen By default, (0,0) corresponds to row 1, column 1 of the Word Processing control (scrollbars located at the origin).
If the pdfOriginScreen constant is combined with the previous constants, (0,0) corresponds to the origin of the screen.
This constant cannot be used on its own.

<X>: Integer

X coordinate (in pixels) to study. This coordinate is relative to the control (if the pdfOriginScreen constant is not specified).

<Y>: Integer

Y coordinate (in pixels) to study. This coordinate is relative to the control (if the pdfOriginScreen constant is not specified).
