[TheKPM]

I am working with jcrop and codeigniter to allow users to crop images that they upload, I want to the image t crop to a size of 90x60 but what ever I try nothing seems to work, my current code looks like this, CONTROLLER\[code\]function save_crop() { $this->load->library('image_lib'); $config['image_library'] = 'gd2'; //$config['library_path'] = '/usr/X11R6/bin/'; $config['source_image'] = './media/images/uploads/company_uploads/' . $this->input->post('image_name'); //$config['new_image'] = './media/images/uploads/company_uploads/cropped' . $this->input->post('image_name').'_'.time(); //die($config['source_image']); $config['x_axis'] = $this->input->post('x'); $config['y_axis'] = $this->input->post('y'); $config['width'] = $this->input->post('w'); $config['height'] = $this->input->post('h'); $config['maintain_ration'] = TRUE; $config['dynamic_output'] = TRUE; $this->image_lib->initialize($config); if(!$this->image_lib->crop()) { echo $this->image_lib->display_errors(); } else { echo "Success"; } }\[/code\]JAVASCRIPT\[code\]$('#jcrop_target').Jcrop({ onChange: showPreview, onSelect: showCoords, aspectRatio: 1, addClass: 'custom', maxSize: [90,60] }); function showPreview(coords) { var rx = 100 / coords.w; var ry = 100 / coords.h; $('#preview').css({ width: Math.round(rx * 500) + 'px', height: Math.round(ry * 370) + 'px', marginLeft: '-' + Math.round(rx * coords.x) + 'px', marginTop: '-' + Math.round(ry * coords.y) + 'px' }); }; function showCoords(c) { $('#x').val(c.x); $('#y').val(c.y); $('#x2').val(c.x2); $('#y2').val(c.y2); $('#w').val(c.w); $('#h').val(c.h); };\[/code\]HTML\[code\]<?php if(isset($upload_data)) :?> <?php if($upload_data['image_width'] > 90 || $upload_data['image_height'] > 60) : ?> <p>Your image is a little large</p> <form action="<?php echo base_url();?>employer/save_crop" method="post"> <div id="uploaded_image"> <img src="http://stackoverflow.com/questions/3551315/<?php echo base_url();?>media/images/uploads/company_uploads/<?php echo $upload_data['file_name'];?>" id="jcrop_target"/> </div> <div id="uploaded_preview"> <img src="http://stackoverflow.com/questions/3551315/<?php echo base_url();?>media/images/uploads/company_uploads/<?php echo $upload_data['file_name'];?>" id="preview"/> </div> <input type="hidden" name="x" id="x" /> <input type="hidden" name="y" id="y" /> <input type="hidden" name="x2" id="x2" /> <input type="hidden" name="y2" id="y2" /> <input type="text" name="w" id="w" /> <input type="text" name="h" id="h" /> <input type="hidden" name="image_name" value="http://stackoverflow.com/questions/3551315/<?php echo $upload_data['file_name'];?>"/> <input type="submit" name="crop_image" value="http://stackoverflow.com/questions/3551315/Crop" /> </form> <?php endif; ?> <?php endif; ?>\[/code\]
