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

arraysizeCol(\PHPExcel_Worksheet $sheet, string $col) : integer
We use the relationship y = ceil(7x) where x is the width in intrinsic Excel units (measuring width in number of normal characters) This holds for Arial 10
stringThe column
integerThe width in pixelssizeRow(\PHPExcel_Worksheet $sheet, integer $row) : integer
By interpolation the relationship is: y = 4/3x. If the height hasn't been set by the user we use the default value. If the row is hidden we use a value of zero.
