| pixelsToEMU($pixelValue) X-Ref |
| Convert pixels to EMU. return: int Value in EMU param: int $pixelValue Value in pixels |
| EMUToPixels($emuValue) X-Ref |
| Convert EMU to pixels. return: int Value in pixels param: int|SimpleXMLElement $emuValue Value in EMU |
| pixelsToCellDimension($pixelValue, \PhpOffice\PhpSpreadsheet\Style\Font $defaultFont) X-Ref |
| Convert pixels to column width. Exact algorithm not known. 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. return: float|int Value in cell dimension param: int $pixelValue Value in pixels |
| cellDimensionToPixels($cellWidth, \PhpOffice\PhpSpreadsheet\Style\Font $defaultFont) X-Ref |
| Convert column width from (intrinsic) Excel units to pixels. return: int Value in pixels param: float $cellWidth Value in cell dimension param: \PhpOffice\PhpSpreadsheet\Style\Font $defaultFont Default font of the workbook |
| pixelsToPoints($pixelValue) X-Ref |
| Convert pixels to points. return: float Value in points param: int $pixelValue Value in pixels |
| pointsToPixels($pointValue) X-Ref |
| Convert points to pixels. return: int Value in pixels param: int $pointValue Value in points |
| degreesToAngle($degrees) X-Ref |
| Convert degrees to angle. return: int Angle param: int $degrees Degrees |
| angleToDegrees($angle) X-Ref |
| Convert angle to degrees. return: int Degrees param: int|SimpleXMLElement $angle Angle |
| imagecreatefrombmp($bmpFilename) X-Ref |
| Create a new image from file. By alexander at alexauto dot nl. return: GdImage|resource param: string $bmpFilename Path to Windows DIB (BMP) image |
