NCast Presentation Recorder Reference Manual
The values entered for W,H are integers in the range 1-1000.
3.5.3. Custom Windows
The Main and PIP input streams must be associated with a Window to define their placement and size on
the frame surface area. The Channel and Sources page defines common settings (such as Full-screen and
Top-right corner), but for custom compositions ten new Windows may be defined.
The values for X,Y,W,H may be entered as integers or percents. If integers are used then these are pixel
widths and heights or pixel offsets from the upper left corner of the frame. If percents are used, then the
dimensions are scaled to the current size of the frame area (e.g. if the frame area is 960x720, then a 50%
window width would be equivalent to entering a value of 480 pixels). The use of percents is convenient when
the frame changes in dimension. The top-left corner is the origin and has an (X,Y) value of (0,0).
3.5.4. Custom Image Overlays
Customized images may be added to the media stream being created. These images would typically be
corporate or organizational logos, trademarks or watermarks, copyright statements, media content or date
annotation, or descriptive information on the course or presentation being viewed (speaker, topic, etc.).
These images must be created in .jpg, .png, .gif or animated .gif format (up to 1280x720 pixels) and may use
transparency to limit the amount of underlying graphical material which is blocked.
The X,Y entries in these fields are integers or percents. The X,Y offset defined will position the image relative
to the top-left corner of the frame.
The enable/disable setting will cause the image to be included or not included in the composite media
stream being created. More than one image (all four, in fact) may be included if required.
THE ENTRIES ON THIS PAGE ARE OVERWRITTEN BY CHANNEL TABLE VALUES WHEN A SESSION IS
STARTED!
The corresponding Channel Table Image Overlays are transferred to the operating Session parameters and
thus initialize the image overlays used during Channel startup. This page may be used to alter Session
image overlays being displayed after a Session has started.
