Adding a Text Watermark to your Images

You can now add a text watermark to the images created by ThumbHTML. You must first define the watermark you wish to add. You can do this by selecting the appropriate menu item, or by checking the 'Add Watermark' checkbox - if a watermark has not been defined, the following dialog box will appear:

The watermark text is added in the first textbox. In the example shown, you can also see the use of some 'macro' commands, that will automatically add the corresponding information when the watermark is created. Some of these can be interpreted immediately (and are shown in the 'Sample' text at the bottom of the dialog). Others, such as the filename, need to be interpreted during the course of execution of the program.
Most of these 'macro' commands are defined by square brackets (e.g.[date]), but one special case is defined by curly brackets - this allows you to use the standard Windows date/time-specifiers, such as {dddd, d mmm yyyy} to represent, say, Sunday, 1 Sep 2002.
A full list of the commands currently supported is available by passing your mouse over the 'codes' text:

As is evident from the dialog, you also can specify which of the given 9 positions the text is to appear in, the font to be used (this list will vary according to the fonts you have installed on your computer), the text height (in pixels), the text offset, the text colour, the smoothing factor and the transparency.

It is recommended that you do not add watermarks to the small thumbnails - reserved this feature for the larger images (e.g. 400 pixels and above). You will have to experiment with the settings, but a good starting point for 600 pixel images say, is a font height of 10 pixels, a font colour of black and a transparency setting of 80%. The font-smoothing is best left at the default setting of 4, since the text tends to look very 'blocky' otherwise.

The text offset is important - the default position (top-right) needs the x-offset to be negative (otherwise the text finishes right at the edge of the image) and the y-offset to be positive (to move the text down from the top edge of the image). Again, some experimentation may be needed, but the defaults of -10 and 10, respectively, seem about right.
