Hi,
I using code listed below from (
http://ellislab.com/forums/viewthread/85727/ ) to create thumbs:
Code:
function process_uploaded_image($filename){
$large_path = $this->config->item('portfolio_path').$filename;
$thumb_path = $this->config->item('thumbs_path').$filename;
//get image size
$img_size = getimagesize($large_path);
$orig_width = $img_size[0];
$orig_height = $img_size[1];
if($orig_width > $orig_height) {
//horizontal picture
$res_width = 450;
$res_height = 10;
$set_master_dim = 'width';
} else {
//vertical picture
$res_width = 10;
$res_height = 400;
$set_master_dim = 'height';
}
//resizing the uploaded image
$resize_config['image_library'] = 'gd2';
$resize_config['source_image'] = $large_path;
$resize_config['maintain_ratio'] = TRUE;
$resize_config['width'] = $res_width;
$resize_config['height'] = $res_height;
$resize_config['master_dim'] = $set_master_dim;
$this->load->library('image_lib', $resize_config);
if (!$this->image_lib->resize()) {
echo "fout bij eerste resize";
echo $this->image_lib->display_errors();
return false;
}
//making a thumbnail
$this->image_lib->clear();
//get image size
$img_size = getimagesize($large_path);
$orig_width = $img_size[0];
$orig_height = $img_size[1];
//calculate offset
if($orig_width > $orig_height) {
//horizontal picture
$diff = $orig_width - $orig_height;
$cropsize = $orig_height - 1;
$x_axis = round($diff / 2);
$y_axis = 0;
} else {
//vertical picture
$cropsize = $orig_width - 1;
$diff = $orig_height - $orig_width;
$x_axis = 0;
$y_axis = round($diff / 2);
}
//actual cropping
$crop_config['image_library'] = 'gd2';
$crop_config['source_image'] = $large_path;
$crop_config['maintain_ratio'] = FALSE;
$crop_config['new_image'] = $thumb_path;
$crop_config['x_axis'] = $x_axis;
$crop_config['y_axis'] = $y_axis;
$crop_config['width'] = $cropsize;
$crop_config['height'] = $cropsize;
$this->image_lib->initialize($crop_config);
if (!$this->image_lib->crop()) {
echo "fout bij crop";
echo $this->image_lib->display_errors();
return false;
}
//resize the cropped image to a thumbnail
$this->image_lib->clear();
$thumb_config['image_library'] = 'gd2';
$thumb_config['source_image'] = $thumb_path;
$thumb_config['maintain_ratio'] = TRUE;
$thumb_config['width'] = 100;
$thumb_config['height'] = 100;
$this->image_lib->initialize($thumb_config);
if (!$this->image_lib->resize()) {
echo "fout bij resizen crop";
echo $this->image_lib->display_errors();
return false;
}
//watermark the resized image
$this->image_lib->clear();
$wm_config['source_image'] = $large_path;
$wm_config['wm_type'] = 'overlay';
$wm_config['wm_vrt_alignment'] = 'middle';
$wm_config['wm_hor_alignment'] = 'center';
$wm_config['wm_overlay_path'] = './images/shutter_watermark.png';
$this->image_lib->initialize($wm_config);
if (!$this->image_lib->watermark()) {
echo "fout bij watermarken";
echo $this->image_lib->display_errors();
return false;
}
return true;
}
