7.4.2 What graphics are suitable for which PDM and what steps
must be carried out?

Not all bitmaps are suitable for display on the PDM.
 In principle, photos should be transformed so that they are optimised when displayed in the given
resolution and colour depth.
 Images with a low contrast are not suitable because the colour differences cannot be displayed on
the PDM.
 If needed, logos and symbols should be optimised for the display on the PDM or drawn again.

To change bitmaps to the correct colour space, ready-to-use colour palettes, e.g. for Adobe
Photoshop, Corel Draw, etc., are available. Please contact your ifm specialist!

allowed colour palettes. The following examples show the different effects of the individual
conversions from the original image:
