I just wrote a function for this earlier tonight. This gets the image size from the server, and checks if it is too large and/or too wide to fit on the word document. It then finds the appropriate scaling factor to size it either at 100% width, height auto, or height 100%, width auto, depending on which ratio is bigger. Word uses 96dpi for images, so all the math is based off that.



 



   getScalingFactor( $imgDimension, $docDimension ) {

      return 99 - ( ( $docDimension / $imgDimension ) * 100 );

   }

   

    if( in_array( $file_data['extension'], $allowed_images ) ) {

        //get image data

        list( $imgWidth, $imgHeight ) = $image_sizes = getimagesize( $file_to_append );

        //max doc sizes at 96dpi

        $docWidth = 718;

        $docHeight = 1122;

        $widthDif = 0;

        $heightDif = 0;

        $widthDif = $imgWidth - $docWidth;

        $heightDif = $imgHeight - $docHeight;



        //get scaling number

        if( $heightDif > 0 && $widthDif >0 ) {

            //both are oversized, which is bigger?

            if( $heightDif >= $widthDif ) {

                //height >= width, scale by height

                $scaling = getScalingFactor( $imgHeight, $docHeight );

            } else {

                //width > height, scale by width

                $scaling = getScalingFactor( $imgWidth, $docWidth );

            }



        } elseif( $heightDif > 0 ) {

            //height has a larger difference than height. Let's scale to match

            $scaling = $func->getScalingFactor( $imgHeight, $docHeight );

        } elseif( $widthDif > 0 ) {

            //width has a larger difference than height. Let's scale to match

            $scaling = $func->getScalingFactor( $imgWidth, $docWidth );

        } else {

            $scaling = 100;

        }



        //prep the options

        $imgOptions = array(

            'name' => $file_to_append,

            'scaling' => $scaling,

            'dpi' => 96,

            //'sizeX' => '718px',

            //'sizeY' => '1122px',

            'spacingTop' => 0,

            'spacingBottom' => 0,

            'spacingLeft' => 0,

            'spacingRight' => 0,

            'textWrap' => 0,

            'border' => 0,

            'borderDiscontinuous' => 1

        );

        

        //create and add the image to a document

        $docx = new createDocx();

        $docx->addImage( $imgOptions );            

        $docOptions = array(

            'marginTop' => 0,

            'marginRight' => 0,

            'marginBottom' => 0,

            'marginLeft' => 0,

            'marginHeader' => 0,

            'marginFooter' => 0

            );

        $docx->modifyPageLayout( 'A4', $docOptions );

        $docx->createDocx( 'one-page-with-image-spanning-fully' );
