如何在Codeigniter中的Image上设置垂直水印？

Question

我想在图像上垂直设置水印。就像下面的图片一样。

这是我的水印代码

$config['source_image'] = '/path';
    $config['wm_text'] = 'WaterMark';
    $config['wm_type'] = 'text';
    $config['wm_font_size'] = '16';
    $config['wm_font_color'] = 'ffffff';
    $config['wm_vrt_alignment'] = 'bottom';
    $config['wm_hor_alignment'] = 'left';
    $config['wm_padding'] = '20';

    $this->image_lib->initialize($config);

    $this->image_lib->watermark();

Answer 1

您可以像这样使用overlay图片：

$config['source_image'] = 'source_image.jpg'; 
$config['wm_type'] = 'overlay';
$config['wm_overlay_path'] = 'overlay_watermark.png';
$config['wm_vrt_alignment'] = 'bottom';
$config['wm_hor_alignment'] = 'left';

$this->load->library('image_lib', $config);
$this->image_lib->watermark();
