I have small question for experts. I have this code snippets that works fine, however I'm trying to make it a small class. Problem I'm having with the class is that it doesn't write any data to the image.
Here's the code snippet.
Code: Select all
$im = imagecreatefromjpeg($original);
$fontType = 'fonts/tahoma.ttf';
$fontSize = 10;
$fontAngle = 0;
$fontColor = imagecolorallocate($im, 0, 0, 0);
foreach ( $formFields as $f )
{
$top = $f['top_pos'] + 14;
$left = $f['left_pos'];
$type = $f['type'];
$value = $f['value'];
imagettftext($im, $fontSize, $fontAngle, $left, $top, $fontColor, $fontType, $value);
}
// output the image
//header("Content-type: image/png");
imagejpeg('new-name.jpg');Code: Select all
class FormCapture
{
var $_fontType = 'fonts/tahoma.ttf';
var $_fontSize = 10;
var $_fontAngle = 0;
var $_fontAdjustment = 14;
var $_fontColor;
var $_image;
function FormCapture( $image )
{
$this->_image = imagecreatefromjpeg( $image );
}
function setFontColor( $red = 255, $green = 255, $blue = 255 )
{
$this->_fontColor = imagecolorallocate( $this->_image, $red, $green, $blue );
return $this->_fontColor;
}
function writeImageData( $data )
{
foreach( $data as $d )
{
$top = $d['top_pos'] + $this->_fontAdjustment;
$left = $d['left_pos'];
$type = $d['type'];
$value = $d['value'];
imagettftext( $this->_image,
$this->_fontSize,
$this->_fontAngle,
$left,
$top,
$this->_fontColor,
$this->_fontType,
$value );
}
}
function saveImage( $name, $quality = 90 )
{
imagejpeg( $this->_image, $name, $quality );
}
}Code: Select all
$fc = new FormCapture($original);
$fc->writeImageData( $formFields );
$fc->saveImage('new-name2.jpg');Any input is very much appreciated.
