Application description
Viewgrader is a simple
tool for the calculation of the edges of the
movie frame for proportional scaling. In the
case of proportional resizing video frame to
scaling width, height must be scaled by the
same aspect ratio. Conversely, scaling the
height, width must be scaled by the same
scale factor. The program calculates the
aspect ratio after scaling one edge, for
scaling another frame edge.
Example of use
In a situation where we are
scaling the video frame size of 320 x 220
pixels to the size of 280 pixels in width,
it is necessary to reduce the height to
proportional size.
Using
the program:
After the change size of the current width,
the program will calculate the value for the
new height. In this example, the scaled
height should reach 192.5 pixel, after
rounded - 192 pixels.
