8.3 DenitionofanobjectintheWebEditor
■ An object is a static text component, a multiline label, a line, a rectangle, an
ellipse, a polygon, an edit eld, a button, or a bar chart. Macros contain many
objects (an oine trend contains 44 objects).
8.4 Handling
■ Touchscreen: The base material of the touchscreen is glass. For this reason, you
should therefore not touch the screen with a screwdriver or hard objects, which
could damage the screen. Use only a nger or special input stylus for operation.
■ In addition: use the right tool for a hardware reset(see "6.2 Reset / Resetting
the device to factory settings" on page 6-2). Do not use a paperclip or pin, but
rather push the microswitch carefully with a Ø 3 mm drill bit.
8.5 Some rules regarding gif images
■ The three timestamps on the MB panel’s graphical display are:
● Repaint video cache
● Decompression in the video cache in case of URL jump and after startup (al-
most linear with the number of pixels). See "8.5.3 Decompression of Gif les:
analysis/calculation" on page 8-4.
● File transfer time via the link if not local.
■ If the total size of the gif les is the same, one large image (max. 512 kbytes) is
better than two smaller ones.
Recommended max. size 798 × 598 pixels (one pixel remains free all-around).
■ It is better to use the same image multiple times in the same project, because
it then has to be transferred only once, decompressed and stored in the video
cache. Place it, for example, in the teq le for the general background.
