Supplementary explanation

• Attribute key 1 and key 2 are attributes that must be set.
• This element cannot be used simultaneously with other elements.
  After executing this element, do not execute any other elements until the callback is returned.
• Execute this element one time only for each <epos-display>, and register images one at a time.
• If success is not returned in <epos-display> by the <response> execution results, including the results of this element, restart the printer.
  Depending on the system environment, it may take some time for the recovery process.
• If the power supply to the customer display is cut off, the registered image is erased.
• As the data size of the image to be registered increases, the processing time becomes longer. (Max. 320 seconds)
• If the data size of the image to be registered is large, and the communication environment is poor, the image may not be registered in this element.
  If the image cannot be registered in this element, use dedicated Utility software.
  For details on the dedicated Utility software, refer to the Technical Reference Guide of each customer display.
• If an image is registered in the specified keycode, it is overwritten and registered.
• Image data expressed in the pixel format of YCbCr422 or YCbCr420 can be used.
• The image size should be about 100 KB although the upper limit of the image size is 1.5 MB.
• Total size of images that can be registered is 1.5 MB.
  This element converts the image format and pixel count so that the customer displays can process the images and then register them. The conversion processing may increase the size of images, so ensure that there is sufficient free space in the download graphics area to accommodate the total size of the images to be registered.
  No error is returned when registration was not successful due to insufficient free space in the download graphics area.
• Use a registration image of 800 x 480 dots or less in size, and ensure that the width is an even number of dots.
• When using a transmission image, use data in the png format.
• When using an image in the jpg format, use an image matching the display area of the customer display.
