PHP eFax: eFaxBarcode Class Reference

This function parses the specified barcode control node.

The function reads the Key, AdditionalInfo, ReadSequence, ReadDirection, Symbology, Location, PageNumber, and the Start & End Points.

Parameters:

[in]

$barcode

The XML node with the BarcodeControl tag.

This function is used to retrieve the barcode key. The key is the actual value of the barcode. In most cases, this is the only function you need to call (assuming you can have only one barcode per fax.)

Returns:

The barcode key or null.

This number represents the page on which the barcode was found. It starts at 1 and grows incrementally.

Note that there can be several barcodes on a single page. To know which barcode it is, you may need to use the sequence number or the coordinates.

Returns:

The page number on which the barcode was found or null.

See also:

eFaxBarcode::get_sequence()

Each barcode on a single page is given a different sequence number. This can be used to know which barcode is being worked on.

The sequence starts at 1 (TBD) and grows incrementally.

Returns:

The sequence number of this barcode or null.

eFaxBarcode::get_page()

The barcode can be found going in any direction (left to right, bottom to top, etc.) This function returns that information.

The direction is defined as a string and can be any of the following:

• "2-Dimentional"
• "Left/Right"
• "Top/Bottom"
• "Right/Left"
• "Bottom/Top"

Returns:

A string with the direction or null.

This function returns the name of the symbology or protocol used to generate the barcode. The names are not defined in the eFax Developer documentation.

Returns:

The symbology used for this barcode or null.

This function is used to get the start and end points of the two barcode areas detected and defining this barcode.

The coordinates may be defined in inches. However, the documentation does not say. You will need to test with a few faxes to make sure that they represent what you think they are.

Note:

If the points were not defined for that barcode, then this function sets them to null. Any one coordinate can be set to null.

Parameters:

[out]	$x_start_a	A reference to a variable to hold the horizontal start point A
[out]	$y_start_a	A reference to a variable to hold the vertical start point A
[out]	$x_start_b	A reference to a variable to hold the horizontal start point B
[out]	$y_start_b	A reference to a variable to hold the vertical start point B
[out]	$x_end_a	A reference to a variable to hold the horizontal end point A
[out]	$y_end_a	A reference to a variable to hold the vertical end point A
[out]	$x_end_b	A reference to a variable to hold the horizontal end point B
[out]	$y_end_b	A reference to a variable to hold the vertical end point B
