    Excel limits the size of BIFF records.

    _addContinue(string $data) : string
    Inherited

    In Excel 5 the limit is 2084 bytes. In Excel 97 the limit is 8228 bytes. Records that are longer than these limits must be split up into CONTINUE blocks.

    This function takes a long BIFF record and inserts CONTINUE records as necessary.

    access private
    inherited_from \PHPExcel_Writer_Excel5_BIFFwriter::_addContinue()

    Parameters

    $data

    string

    The original binary data to be written

    Returns

    stringA very convenient string of continue blocks

    General storage function

    _append(string $data) 
    Inherited
    access private
    inherited_from \PHPExcel_Writer_Excel5_BIFFwriter::_append()

    Parameters

    $data

    string

    binary data to append

    Calculate the vertices that define the position of the image as required by the OBJ record.

    _positionImage(integer $col_start, integer $row_start, integer $x1, integer $y1, integer $width, integer $height) 

    +------------+------------+ | A | B | +-----+------------+------------+ | |(x1,y1) | | | 1 |(A1)._______|______ | | | | | | | | | | | +-----+----| BITMAP |-----+ | | | | | | 2 | |______________. | | | | (B2)| | | | (x2,y2)| +---- +------------+------------+

    Example of a bitmap that covers some of the area from cell A1 to cell B2.

    Based on the width and height of the bitmap we need to calculate 8 vars: $col_start, $row_start, $col_end, $row_end, $x1, $y1, $x2, $y2. The width and height of the cells are also variable and have to be taken into account. The values of $col_start and $row_start are passed in from the calling function. The values of $col_end and $row_end are calculated by subtracting the width and height of the bitmap from the width and height of the underlying cells. The vertices are expressed as a percentage of the underlying cell width as follows (rhs values are in pixels):

    x1 = X / W *1024 y1 = Y / H *256 x2 = (X-1) / W *1024 y2 = (Y-1) / H *256

    Where: X is distance from the left side of the underlying cell Y is distance from the top of the underlying cell W is the width of the cell H is the height of the cell The SDK incorrectly states that the height should be expressed as a percentage of 1024.
