Add watermark for Baidu Ueditor editor upload image

Form:http://www.uphtm.com/php/255.html

Ueditor Editor upload image is automatically extracted, but the picture does not have a watermark function, the following small series and you see together.

Ueditor Editor does not upload images and watermark function, need to carry out two development, this example is in the PHPCMS system Baidu Editor two times to develop, add upload images and watermark function.

First open the Ueditor Editor file directory of the PHP folder, open the Uploader.class.php, the Phpcms watermark method to copy, add to this class all member methods of the last side, and then modify the following:

2. Picture plus watermark
4. Public function watermark ($source, $target = ", $w _pos =", $w _img = ", $w _text = ' 99danji ', $w _font = 8, $w _color = ' #f f0000 ') {

Compared to the part I modified, because the PHPCMS watermark can be managed in the background settings, the PHPCMS comes with the watermark method by reading the configuration file to get the path, and read the database settings to get the parameter settings, then these places need to be set manually.

By the way, the Upfile method also adds a function:

1. if ($this->watermark) {
2. $this->watermark ($this->filepath, $this->filepath);
3. }

Then open the Ueditor Baidu Editor php directory under the action_upload.php file, plus whether to add the watermark parameters:

1. /* Upload configuration */
2. $base = "Upload";
3. Switch (Htmlspecialchars ($_get[' action ')) {
4. Case ' Uploadimage ':
5. $config = Array (
6. "Pathformat" = $CONFIG [' Imagepathformat '],
7. "MaxSize" = $CONFIG [' Imagemaxsize '],
8. "Allowfiles" = $CONFIG [' Imageallowfiles ']
9. );
10. $fieldName = $CONFIG [' Imagefieldname '];
11. $watermark = true;
12. Break

Then there is another sentence to be changed:

1. /* Generate the Upload instance object and complete the upload */
2. $up = new Uploader ($fieldName, $config, $base, $watermark);

This will be done, this article is mainly to provide ideas and reference.
