Blow-Up

 

Watch a Video Presentation

 

This tool gives a magnified view of the image under the cursor in the Display Area. The center red square in the Blow-Up area corresponds to the pixel under the cursor in the Image Display Area.

 

Note:

 

To help graphic performances, the blow-up window is refreshed only when the processor is free. Thus, if the mouse is moved, the image in the blow-up window may not follow immediately.

The Image

A blow-up of the image, centred on the position of the cursor will be displayed here.

 

The Scale slider

The magnification of the blow-up image can be modified with the slider  located to its right. At its smallest magnification (cursor at the bottom), one pixel of the screen shows one pixel of the image.

 

 

From the Display Area

 

The image in the blow-up window is centered around the current cursor position when the cursor is over a frame.
