Using Flash
You can use flash memory when the graphic image is used by several
formats, because you only have to send the graphic image once. This
eliminates the need to send the graphic image repeatedly. See “Placing the
Graphic in a Format,” for more information about using the graphic packet in
aformat.
Creating a Graphic Packet
Your graphic packet can contain
¨
bitmapped fields (for bitmapped images)
¨
constant text fields
¨
lines
¨ boxes.
Images using hex representation or run length encoding are bitmapped
images. See “Designing Bitmapped Images” to design your bitmapped
image.
Once you design your graphic image, you are ready to define a graphic
packet. This packet generates the graphic image you use in a format.
Positioning the Graphic Image
This section explains how to position the graphic image within a graphic
packet header, a field of a graphic packet, or within a format.
Within the Graphic Packet Header
When you are using RAM, the row and column parameters in the graphic
header are usually 0,0, because placement is controlled by the graphic field
in your format.
When you are using temporary storage, these parameters control the
placement of the graphic image on the supply.
