9.7.4 Restrictions for Picture Display
(CF Image Display)
Displays JPEG files 1024×768 pixels or less.
For a JPEG file, the image displays with
reference to the top-left corner of the display area. However, if
an image is larger than the display area, only the portion that is
in the display area, from the top-left corner, will display. With
update display, the display area is filled with the clear
color.
Displayed JPEG files cannot be automatically
erased. JPEG files that are displayed when the Trigger Bit Address
turns ON (or OFF) will remain displayed even when the Trigger Bit
Address turns OFF (or ON).
You cannot rotate the JPEG image, even if you
change the display unit [Orientation] or rotate the Picture
Display's display area. When you want to display the image rotated,
first rotate the JPEG image itself.
When using multiple Picture Displays on a screen
to display JPEG files, and when a screen change occurs, the order
in which parts are displayed may differ from the drawing order.
When the [Display Method] is set to [File
Manager], you can display JPEG files on the CF card or USB storage.
When the [Display Method] is set to [Specify File Name], you can
display JPEG files only on the CF card.
When [Display Method] is [File Manager]
If you use the [File Manager] Special Data
Display part to delete a displayed JPEG file, the image will
continue to display. The image is cleared by overwriting with
screen change or another image.
The File Manager coordinates information about
the displayed image with the Picture Display part. As a result,
nothing displays when trying to display a JPEG image from the [File
Manager] Special Data Display part on screens without a Picture
Display part. If you then change screens to a screen with a Picture
Display, the JPEG file selected in the File Manager will
display.
You can display only one picture display
interacting with a file manager on a screen. When multiple picture
displays are displayed at a time by placing them on a window
screen, they act in the following priority order.
Ones placed on a base screen
Ones placed on a local window
Ones placed on a global window
When [Display Method] is [Specify File
Name]
Specify the data to store with a full path
(folder name and file name). The full path should be 20 single-byte
characters (10 words) or less. If it is less than 20 characters, be
sure to store "00h" at the end.
Put " \ " between the folder name and file name
in a full path.
The file name should be 8 single-byte characters
or less. Only Bin and JPEG files are supported.
When [Specification Method] is set to [Address],
you can only use the display unit's internal addresses (LS, USR)
for the address in the [Display Screen Specification Address]
field.
When you specify LS area, Text Data Mode only supports 1, 2, 4, and
5. If you set a different Text Data Mode, images may not be
displayed correctly.
