Specifies the area to store data, size, and the address of the palette.
Data Address Specifies the first address in memory of the area for display as image data (in
hexadecimal notation).
Palette Address Specifies the first address in memory of the color-palette data (in hexadecimal
notation; valid when “8Bit” has been selected for RGB or BGR).
Specifies the width and height of the image.
Width (Pixel) Specifies the width of the image (unless a prefix is included,
values are treated as decimal numbers).
Height (Pixel) Specifies the height of the image (unless a prefix is included,
values are treated as decimal numbers).
Width/Height Size
Buffer Size (Hex) Displays the size of the buffer required for image display as
obtained from the width and height (in hexadecimal notation).
Enable Redraw
Continuously
Specifies the redraw continuously function has been enabled.
Specifies the number of frames to be redrawn image continuously.
Frame Count Specifies the number of frames (2 or more).
Buffer
Information
Image Data
Buffer Full Size
(Hex)
Displays the size of the buffer required for images display as
obtained from the width and height, and the number of frames
(in hexadecimal notation).
Specifies whether display is on all or part of the screen (in hexadecimal notation; valid when “8Bit” has
been selected for RGB or BGR).
Specifies the entire/part to be displayed in the image.
Full Size The image is displayed on the whole screen.
View Mode
Part Size The image is displayed on part of the screen.
Specifies where the display of data is to start.
Top Display of data starts at the upper-left position.
Start Position
Bottom Display of data starts at the lower-left position.
Specifies the start position of the image where part of the image is to be displayed.
(Valid when "Part Size" is selected)
X Position Specifies the X-coordinate of the start position (unless a prefix
is included, values are treated as decimal numbers).

Y Position Specifies the Y-coordinate of the start position (unless a prefix
is included, values are treated as decimal numbers).
