Chapter 4 Application Development Information Displaying Graphics Data Graphics data that can be displayed in the text and image areas are as follows. For specifications of available JPEG and PNG data, see the link below. U "Product Specifications" on page 54 Storing Graphics Data To display graphics data in the text or image area, store the data in the memory dedicated for graphics data. There are two types of memory. It is recommended to use DM-D70 Utility or Epson TM Utility to store data in the NV memory. Graphics data can be converted in appropriate format and then stored. It may take about 110 seconds to store graphics data in the NV memory.
This is because an optimization of the NV memory is performed. During the optimization, a message “Optimizing” is displayed on the screen. 45 Type of Graphics Description Image data • Displayed in the image area in the standard mode. • By specifying the display size, the image can be reduced or enlarged and displayed in the imag e area. Frame • Graphics data that can be always displayed in the text area to decorate the text area. To display character string over the frame, the portion of the frame PNG data that overlap with characters needs to be transmissive. • Match the size of the frame data (horizontal and vertical pixel size) with the size of the text area.

If the size of the graphics data is larger than the image area, the graphics is reduced so that it fits inside the image area. • All graphics data used for the slide show need to be uniform in size. If they are different in size, a n immediately preceding image remains.
