7.15 Setting bitmap
7.15.1 Sending bitmap file
You can set the bitmap image to be displayed on the sink device. Up to four bitmaps can be registered. IDK's
logo is displayed by factory default.
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 sink device.
■ Conditions of bitmap file
The MSD supports DIB (Device Independent Bitmap) with a header generally used for Windows, and those
files have to meet the following requirements:
Item
File header
Information header
The number of colors
Resolution
Compression format
■ Transferring bitmap file
You can use browser, RS-232C or LAN communication.
From browser
To send bitmap files to the MSD via WEB browser, such as Microsoft Internet Explorer, enter "/bitmap.html"
after the IP address in the address bar of the WEB browser.

[Table 7.20] Conditions of bitmap file
"BITMAPFILEHEADER"
"BITMAPCOREHEADER"(for OS/2) /
"BITMAPINFOHEADER"(for Windows)
2 colors (monochrome, 1 bit), 16 colors (4 bits), 256 colors (8 bits), 16.77
million colors (TRUE COLOR, 24 bits)
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 (8 bits); 3 bytes per pixel for 16.77 million colors
(TRUE COLOR, 24 bits).
No compression (BI_RGB), 8 bit-run-length compression (BI_RLE8), 4
bit-run-length compression (BI_RLE4)
