Hey, my problem is to calculate scale to press zoom-in, zoom -out.
To init application i am calculate the current scale. to press zoom-in i

how i can make?

Hello,
Do you want the scale itself, or do you want to convert between map
and screen coordinates ? For example, to display the cursor position
in map coordinates...
If the latter, have a look at RendererUtilities.worldToScreenTransform()

Hey, i am a problem to calculate scale. the method to calculate scale in
RendererUtilities have the params ReferencedEnvelope envelope,
int imageWidth, int imageHeight, double DPI.
The envelope is getContext().getLayerBounds() o
getContext().getAreaOfInterest() ?
What is
