Resizing of transparent/animated gifs [solved]

#15
[eluser]sidhartha[/eluser]
replace the line
Code:
$copy($dst_img, $src_img, 0, 0, $this->x_axis, $this->y_axis, $this->width, $this->height, $this->orig_width, $this->orig_height);

with the following at line number 512 or around it in Image_lib.php. it maintains transparency for both gif and png images. note the imagefilledrectangle() replacing
imagefill(). with imagefill() the transparent part becomes black. but imagefilledrectangle() maintains transparency.
Code:
$proprts         = $this->get_image_properties($this->full_src_path, TRUE);
        $cr_img_type    = $proprts['image_type'];
        //$cr_width        = $proprts['width'];
        //$cr_height        = $proprts['height'];
                    
                    
        if ($cr_img_type == 3)//for png
        {
                        
            imagealphablending( $dst_img, false );
            imagesavealpha( $dst_img, true );
            $transparent_index = imagecolorallocatealpha($dst_img,0,255,0,127);
         //  imagefill($dst_img, 0, 0, $transparent_index);
            imagefilledrectangle($dst_img, 0, 0, $this->width, $this->height, $transparent_index);
            $copy($dst_img, $src_img, 0, 0, $this->x_axis, $this->y_axis, $this->width, $this->height, $this->orig_width, $this->orig_height);
          
        

        }
        
        else if($cr_img_type == 1)//for gif
        
        {
             $transparent_index = imagecolortransparent($src_img);
                  if ($transparent_index >= 0) {
                      imagepalettecopy($src_img, $dst_img);
                    //  imagefill($dst_img, 0, 0, $transparent_index);
                      imagefilledrectangle($dst_img, 0, 0, $this->width, $this->height, $transparent_index);
                      imagecolortransparent($dst_img, $transparent_index);
                      imagetruecolortopalette($dst_img, true, 256);
                  }
                    
            $copy($dst_img, $src_img, 0, 0, $this->x_axis, $this->y_axis, $this->width, $this->height, $this->orig_width, $this->orig_height);
        }
        else//for other
       {
            
        $copy($dst_img, $src_img, 0, 0, $this->x_axis, $this->y_axis, $this->width, $this->height, $this->orig_width, $this->orig_height);    
        
        }
