The watermark modification applies and image overlay. You need to store your watermark image (png, gif, tiff) on an absolute path on the server. Then you can define a distance from the four borders in pixel (margin left, margin top, margin right, margin bottom). You can leave the margins empty. You must set the opacity (0.1 to 1) used for transparency and an aspect ratio - the ratio of the width of a shape to its height (e.g. 8:5, 16:10 and 1.6:1 are the same aspect ratio).

| widthRatio | a number larger than 0, 0 is forbidden e.g. 0.5 for half the size or 2 for double the size | Scales the watermark width according to the size of the final image. The widthRatio is used for orientation portrait. Use a square watermark file to ensure better-proportioned results. |
| heightRatio | a number larger than 0, 0 is forbidden e.g. 0.5 for half the size or 2 for double the size | Scales the watermark height according to the size of the final image. The heightRatio is used for orientation landscape. Use a square watermark file to ensure better-proportioned results. |
