How to generate on the fly images with image_lib?

[eluser]Sinclair[/eluser]
Hi,

First of all, thanks for the replys.

I have found something that works, but I need to resize and watermark on the fly, whitout changing the original image file.

I have to functions that I'am testing:

Code:

function get_photo($folder, $file){
        
        $path = 'c:/xampp/htdocs/acomp_www/' . $folder . '/' . $file;
        #$path = 'c:/xampp/htdocs/acomp_www/1/2.jpg';
        #$this->load->library('image_lib');                    
           #$this->image_lib->clear();
        $imageinit['image_library']     = 'GD2';
        $imageinit['quality']            = '100%';
        $imageinit['dynamic_output']    = TRUE;
        #$imageinit['create_thumb']    = FALSE;
        $imageinit['source_image']         = $path;
        #$imageinit['maintain_ratio']     = false;
        $imageinit['width']             = '200';
        $imageinit['height']             = '150';
    
        $imageinit['wm_type'] = 'overlay';
        $imageinit['wm_overlay_path'] = 'c:/xampp/htdocs/acomp_www/1/w.png';
        $imageinit['wm_padding'] = '0';
        $imageinit['wm_hor_alignment'] = 'bottom';
        $imageinit['wm_vrt_alignment'] = 'center';
        
        $this->image_lib->initialize($imageinit);
        $this->image_lib->watermark();
        #$this->image_lib->clear();
        $this->image_lib->resize();
        if(!$this->image_lib->resize() && !$this->image_lib->watermark()){
        echo $this->image_lib->display_errors();
        }
    }

This function, Watermarks On The Fly, but not resize.

Code:

function get_photo($folder, $file){
        
        $path = 'c:/xampp/htdocs/acomp_www/' . $folder . '/' . $file;
        $this->load->library('image_lib');
        
        $config['thumbnail'] = array('source_image' => $path,
                                     'width' => '200',
                                     'height' => '150',
                                     'dynamic_output' => true);
        $this->image_lib->initialize($config['thumbnail']);
        $this->image_lib->resize();
        
        $this->image_lib->clear();
        
        $config['watermark'] = array('wm_type' => 'overlay',
                                     'source_image' => $path,
                                     'wm_overlay_path' => 'c:/xampp/htdocs/acomp_www/1/w.png',
                                     'wm_padding' => '20',
                                     'dynamic_output' => true,
                                     'create_thumb' => 'false',
                                     'wm_hor_alignment' => 'bottom',
                                     'wm_vrt_alignment' => 'center');
        $this->image_lib->initialize($config['watermark']);
        $this->image_lib->watermark();    
        
    #    if(!$this->image_lib->resize() && !$this->image_lib->watermark()){
        #echo $this->image_lib->display_errors();
        #}
    }

This function resize and watermarks, but when watermarking, change the image, add the watermark to the image withthe original image size.




My question. How can I get real Resize and Watermarking On The Fly without changing the original image files? Can you give me some clues?
