Wrong annotation placement

Hello, I'm writing indoor navigation app and using JCTiledScrollView. My map has predefined points (coordinates in pixels) for each facility. When I trying to set annotation for facility (set annotation for facility coordinates), annotation is places in a wrong place.

Here the screenshot of device screen http://mihael.me/sites/default/files/screenshot1.png
Marker must be on Century Theatres , but it does not :( I debug the app, and coordinates are passed correctly.
Maybe I'm doing something wrong ? Maybe I must convert pixels to points or something like that. Can you please help me.
