A maximum of slightly less than 2 Mega Pixels can be stored in flash memory. The
pixels can be used for a single large image, or for many smaller images. For
example, one full frame image for 1920x1080 video can be stored, or up to 64
images at 240 by 135 pixels each.
When an image is uploaded, an identification number (ID) is assigned to the
image. The ID is used to select that image when it is to be displayed on the
overlay. It is recommended to keep a record of the ID number used when images
are uploaded.
The DX2200 Software Uploader program can show a list of images that are stored
in the memory with their sizes and ID, and also reports how many pixels are
available in flash memory. Individual images can be deleted, or the entire memory
can be cleared to remove all images.
The DX2200 Uploader software accepts image files in PNG and JPEG format. The
PNG file format supports Red, Green, and Blue channels, and also supports an
optional transparency channel to set the visibility of each pixel. The JPEG file
format support Red, Green and Blue channels. The DX-2200 accepts files with or
without the transparency channel. When a file without transparency is uploaded,
all pixels are visible. When the file includes a transparency channel, different parts
of the image can have different visibility for example to generate smooth edges, or
to overlay images that are not rectangular.
Note: Most PNG files do not include a transparency channel. To generate a PNG
file with transparency an image editor such as Adobe Photoshop or Gimp can be
used.
Note: The capability to store images permanently in flash memory requires a unit with
16 MB of serial flash memory. Units shipped prior to April 2014 do not have the required
flash memory and cannot permanently store images. Images can still be uploaded to the
unit, but are lost on reset or power-off.
