Parameters:

pScreen - Punto en pixels.

at1 - Matriz de transformación.

Returns:

screenPixelToViewPortPixelRatio

public static double screenPixelToViewPortPixelRatio(LayoutPanel lyt_panel,
                                     double frame_height_cm,
                                     int frame_vp_img_height)

Gets the proportion between the number of pixels used on the screen (physical pixels) and the "logical" pixels used in the viewport of a frame (imageHeight, etc). For example if viewport image height is 500 and the frame actually needs 100 pixels in height (due to zooming) then this method returns 5.

Parameters:

lyt_panel -

frame_height_cm - frame height in cm

frame_vp_img_height - frame viewport image height (pixels)

Returns:

getLastMessage

public static String getLastMessage(Throwable ex)
