In Android you can have 3 different app graphic resolutions. High, middle and low density. With WD mobile you can only have 1 resolution.
This is true for image controls, except for the app icon. There you can declare the three different files.
Workaround: create an image file (e.g. png) in a three times bigger size. Example: you need an 48x48 pix image. With Photoshop you create a PNG in 144x144 with 72 dpi. You put this file as an image control into WM and resize it to 48x48. Then you choose 'homothetically centered extended' as display mode. This way the image should be displayed correctly in any screen density.
PCSoft should add the possibility to store three different image files for each image control in Android.
