I need help finding the left x coordinate when I right align an image

[Larene Spitler]

$pdf->Image($src, $x, $y, 0, 0, $ext, '', '', true, 300, 'R');

What is the new x value?

See GetX() and GetAbsX() in the documentation.

Sorry. I only just read the subject line.

I would do some regular PHP to find the dimensions of your image and then do the maths based on the DPI.

See: http://php.net/manual/en/function.getimagesize.php

I am unfamiliar with the math needed.

It will be something like:

$a = $imageWidth/300; //Gives image width in inches;
$x = $pageWidth - $a - $rightMargin;

This will work if your default unit is inches, otehrwise you'd need to convert units.

This is what I came up with:

            $x = $pdf->GetX();
            $y = $pdf->GetY();
            if ($float == 'right')
            {
                $pdf->Image($src, $x,  $y, 0, 0, $ext, '', '', true, 72, 'R');
                $page = $pdf->getPage();
                $y = $pdf->GetY();
                $xb = $pdf->getImageRBX();
                $yb = $pdf->getImageRBY();
                $filename = '/home/storytelling/public_html' . $src;
                list($width, $height, $type, $attr) = getimagesize($filename);
                $wid = ($width / $pdf->getImageScale()) / $pdf->getScaleFactor();
                $x = $xb - $wid - 1; // add a space to the left
                $regions = array();
                $region = array();
                $region['page'] = $page;
                $region['xt'] = $x;
                $region['yt'] = $y;
                $region['xb'] = $x;
                $region['yb'] = $yb;
                $region['side'] = 'R';
                array_push($regions, $region);
                // set page regions, check also getPageRegions(), addPageRegion() and removePageRegion()
                $pdf->setPageRegions($regions);
            }
