(2) In case when the monitoring is closed down due to the increase of the memory share in spite of the
image change operation, contact the A/S center close by.
Question
After continuously adding projects to the screen, and adding/editing objects, the operation
speed has been slowed down.
Phenomenon
After adding projects to the screen and also adding/editing objects, it feels like the operation
speed of XGT Panel gets slowed down.
<Causes>
(1) The amount of image used for projects is big.
(2) In order to increase the screen operation speed, XGT Panel maintains the used images in the memory in
advance. Since the memory resource has limitation, they cannot be maintained in the memory once the
amount of image exceeds a certain limit. Whenever they are needed, thus, they are read from the file
system and then expressed on the screen. This could be the reason why the screen operation speed gets
slowed down.
<Solution>
(1) In case of using vector image instead of raster image, the memory share can be reduced. In the graphic
library of XP-Builder, the image group marked as OOO_R is the raster image group while the image
group marked as OOO_V is the vector image group.
(2) In case when there is no proper vector image, the desired image can be composed by using various
functions of figures (circle, square, straight line and etc.).
(3) Removing unnecessary background screen, the screen is composed by applying the background colors.
