GdImage|resource —pixelsToCellDimension()
Convert pixels to column width. Exact algorithm not known.
public
static pixelsToCellDimension(int $pixelValue, Font $defaultFont) : float|int
By inspection of a real Excel file using Calibri 11, one finds 1000px ~ 142.85546875 This gives a conversion factor of 7. Also, we assume that pixels and font size are proportional.
Parameters
- $pixelValue : int
-
Value in pixels
- $defaultFont : Font
Return values
float|int —Value in cell dimension
pixelsToEMU()

Return values
int —Value in EMU
pixelsToPoints()
Convert pixels to points.
public
static pixelsToPoints(int $pixelValue) : float
Parameters
- $pixelValue : int
-
Value in pixels
Return values
float —Value in points
pointsToPixels()
Convert points to pixels.
public
static pointsToPixels(int $pointValue) : int
