sizeCol(\PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $sheet, string $col = 'A') : int
Get the width of a column in pixels. 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.

The width in pixels
sizeRow(\PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $sheet, int $row = 1) : int
Convert the height of a cell from user's units to pixels. 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.

The width in pixels
getDistanceX(\PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $sheet, string $startColumn = 'A', int $startOffsetX, string $endColumn = 'A', int $endOffsetX) : int
Get the horizontal distance in pixels between two anchors The distanceX is found as sum of all the spanning columns widths minus correction for the two offsets.

| string | $startColumn | |
| int | $startOffsetX | Offset within start cell measured in 1/1024 of the cell width |
| string | $endColumn | |
| int | $endOffsetX | Offset within end cell measured in 1/1024 of the cell width |
Horizontal measured in pixels
getDistanceY(\PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $sheet, int $startRow = 1, int $startOffsetY, int $endRow = 1, int $endOffsetY) : int
Get the vertical distance in pixels between two anchors The distanceY is found as sum of all the spanning rows minus two offsets.
| \PhpOffice\PhpSpreadsheet\Worksheet\Worksheet | $sheet | |
| int | $startRow | (1-based) |
| int | $startOffsetY | Offset within start cell measured in 1/256 of the cell height |
| int | $endRow | (1-based) |
| int | $endOffsetY | Offset within end cell measured in 1/256 of the cell height |
Vertical distance measured in pixels
oneAnchor2twoAnchor(\PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $sheet, string $coordinates, int $offsetX, int $offsetY, int $width, int $height) : array
Convert 1-cell anchor coordinates to 2-cell anchor coordinates This function is ported from PEAR Spreadsheet_Writer_Excel with small modifications.
Calculate the vertices that define the position of the image as required by the OBJ record.

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
