```
public void setMaxZoom(float max)
```
    Set the max zoom multiplier. Default value: 3.
    
    Parameters:
    
    max - max zoom multiplier.
  - getMinZoom
```
public float getMinZoom()
```
    Get the min zoom multiplier.
    
    Returns:

  - setZoom
```
public void setZoom(float scale)
```
    Set zoom to the specified scale. Image will be centered by default.
    
    Parameters:
    
    scale -
  - setZoom
```
public void setZoom(float scale,
                    float focusX,
                    float focusY)
```
    Set zoom to the specified scale. Image will be centered around the point (focusX, focusY). These floats range from 0 to 1 and denote the focus point as a fraction from the left and top of the view. For example, the top left corner of the image would be (0, 0). And the bottom right corner would be (1, 1).
    
    Parameters:
    
    scale -
    
    focusX -
    
    focusY -
  - setZoom
```
public void setZoom(float scale,
                    float focusX,
                    float focusY,
                    ScaleType scaleType)

    Set zoom to the specified scale. Image will be centered around the point (focusX, focusY). These floats range from 0 to 1 and denote the focus point as a fraction from the left and top of the view. For example, the top left corner of the image would be (0, 0). And the bottom right corner would be (1, 1).
    
    Parameters:
    
    scale -
    
    focusX -
    
    focusY -
    
    scaleType -
  - setZoom

public void setZoom(PDFZoomImageView img)
```
  - getScrollPosition
```
public android.graphics.PointF getScrollPosition()
```
    Return the point at the center of the zoomed image. The PointF coordinates range in value between 0 and 1 and the focus point is denoted as a fraction from the left and top of the view. For example, the top left corner of the image would be (0, 0). And the bottom right corner would be (1, 1).
    
    Returns:
    
    PointF representing the scroll position of the zoomed image.

    Set the focus point of the zoomed image. The focus points are denoted as a fraction from the left and top of the view. The focus points can range in value between 0 and 1.
    
    Parameters:
    
    focusX -
    
    focusY -
  - onMeasure
```
protected void onMeasure(int widthMeasureSpec,
                         int heightMeasureSpec)
