Defining a text image
Screen capture can never be prevented but ImageSafe can frustrate
it by
providing the option to display a line of text over the image. Text overlays are often
superior to image overlays in that no amount of screen captures and editing can remove the
text from the image
Various options are available for a text overlay
- The text itself can be anything you can type. The text will be repeated across the image.
- Text animation - the text can move or be static
- Text color - the default color is light gray but it can be anything you choose. Text is
always solid and not transparent so choosing a color that suits the images is best.
- The text position - top, center or bottom
- The text offset - this is the offset from the position. If the position is "center"
then the offset moves the image down. If it's "bottom" then the image is moved up.
- The text font - these are the standard fonts common to all browsers.
- Spaces in gap - this is the number of spaces between the repeating text across the image.
The Timing
By pressing
the "Timing" button it's possible to change the timing parameters of the text movement. The
parameters that can be changed are:
- The inter-frame delay time specified in milliseconds
- The number of pixels moved after each delay
The initial timing is for the delay to be 150 and the step to be 2. For a smoother movement it
recommended you use a delay of 35 and a step of 1.
Previewing
Pressing the preview button will let you see what the image looks like with the overlay
text before generating the applet. Before the preview button will work, a main image
must be first selected using the file chooser on the right hand side of the display.
