FVS free watermarking allows you to apply a transparent (physical) watermark to your image in order to protect its copyright value, it is a simple example of the type of services we provide. To perform a simple image watermark simply select a file to watermark, add some text and hit 'Watermark now' a window will appear and the text you typed in will appear at the top left hand side of your picture, you can simply right click on it and save it locally.
You can also add an image watermark by selecting a file you wish to 'overlay' eg a logo, this will appear in the centre of your image and depending on the transparency level, 1 being the lightest 255 being heaviest, the image will be as faint or as opaque as you wish.
Template files.
You can add custom shaped watermarks to your images. Up until now you simply adjust the
level of transparency across the whole watermark image, and because it is a bitmap you
will always see a square image. Obviously logos etc. can be all types of shapes so to
apply a custom shape you use a template file which acts as a 'mask' between the main
image and the watermark image, whereby any area of black (RGB 255,255,255) is not
passed through.
The template files black areas are not passed through to the main image, when the
watermark is applied. By adjusting the level of grey (for example RGB, 70,70,70)
determines the level of transparency when the watermark is applied to all non black areas
(the transparency level will be ignored).
So for example with this watermark file (which is simply the colour white, so that white text from the template file is generated):
And this template file (remember anything black does not get passed through):
You get this result when the above files are applied to the FVS watermarker:
This use of the
template file allows the user full flexibility in determining the shape of the
watermark and by changing the RGB levels the colour bias of the logos transparency.
To create the template files use a photo editor package.
