Tool that inserts watermarks into screen presentations to make them
visually disruptive.
When the application is running, an overlay is placed over the entire
screen. The layer consists of diagonal lines, (animated) logos, and
message texts used as signatures.
The logo and signature can be resized, rotated, and positioned via
drag & drop.
The application has two states:
-
Layout mode
Captures mouse gestures and lets you change the size and position
of logos and signatures, as well as their transparency using the
mouse wheel.
(A green frame at the edges of the screen indicates you're in layout
mode.) -
Shielding mode
Passes mouse gestures to the underlying applications.
(Keyboard shortcuts remain functional if the application has focus.)
You can toggle between the modes using the space bar or the
return key.
On first launch, if no settings file exists, one signature and one logo
object will be created as examples. Upon quitting the application, a
settings file is saved in the program directory.
The settings file contains all configuration values in JSON format and
can also be edited manually.
Placeable objects (signatures and logos) can be freely added to the
"objects" list in the settings file. Supported logo image formats are
SVG, PNG, BMP, JPG, and GIF. For GIFs, only the first frame is shown by
default. To enable animation, set the object's "type" in the settings
file from "Image" to "AnimatedGif".
