7.14 Bitmap

The MSD outputs an bitmap for approximately 5 seconds after it is turned on by setting "7.14.2 Bitmap
output [BITMAP OUTPUT]" to "ON", selecting a video input set in "7.14.6 Input bitmap channel
assignment [CHANNEL ASSIGN]", or setting "7.14.7 Bitmap output at startup [POWER ON BITMAP]" to
"ON". IDK's logo is displayed by factory default, but you can change it to the bitmap you want to display. You
can register up to four images, and you can capture input videos to register it as bitmap images.

7.14.1 Bitmap transfer

To send bitmap files to the MSD, you can use browser, RS-232C communication, and LAN communication.
The MSD supports DIB (Device Independent Bitmap) with a header generally used for Windows, and those
files have to meet the following requirements:
・File header:
Having "BITMAPFILEHEADER"
・Information header:
Having "BITMAPCOREHEADER" (for OS/2) or "BITMAPINFOHEADER" (for Windows)
("BITMAPV4HEADER" or "BITMAPV5HEADER" are not supported.)
・The number of colors:
One of the following: 2 colors (monochrome, 1 bit), 16 colors (4 bits), 256 colors (8 bits), 16.77 million
colors (TRUE COLOR, 24 bits)
・Resolution:
The maximum resolution: [Horizontal resolution x Vertical resolution x The number of bytes per pixel] =
8,388,608 bytes or less. If you register several bitmaps, the total bytes of all bitmaps should be 8,388,608
bytes or less. (Aspect ratio does not matter as long as it is within the maximum resolution).
Bytes per pixel: 1 byte per pixel for 2 colors (monochrome, 1 bit), 16 colors (4 bits), and 256 colors (8bits);
3 bytes per pixel for 16.77 million colors (TRUE COLOR, 24 bits).
Bitmaps can be enlarged but cannot be reduced. The larger the resolution is, the longer the output time
will be, and it may take a maximum of approximately six seconds to output a bitmap. Register a bitmap
having smaller resolution than that of the display device.
・Compression format:
One of the following: No compression (BI_RGB), 8 bit-run-length compression (BI_RLE8), 4 bit-run-length
compression (BI_RLE4)
