Click to expand...
Did you get any error?
B4X: 
getPageBitmap (page As Int, zoom As Int, x As Int, y As Int, rotation As Int, prefXSize As Int, prefYSize As Int)
At first i would try to change the size units. Try to use 100dip, 100dip instead of just 100

You can try to use PDFRenderer. There is an Example showing the pages as Bitmap....
