Here are some examples for making an image grayscale on-the-fly.
i_o_gray url command modifier you can make your images grayscale on-the-fly.
The default behaviour of the grayscale effect is to apply the grayscale function on the whole image. However you can select specific region to make it grayscale.
i_c_y you can set the center of the rectangle and using
i_w you can specify the height and width of the region you want to make grayscale. In this example we set the center of grayscale effect to (100, 300) and the rectangle dimension is (200, 200).
When comparing to the original image you see that the bus ad banner is now grayscaled.
Using Inteliver A.I. object detection feature you can select different objects in your images and then grayscale them.
In this example, by using object selector
i_c_object_car we will only make the car in the image grayscale.
You can use variety of selection methods including face selectors to grayscale faces as well.
Using Inteliver command chain you can apply effects multiple times using
/ separator. With the help of this feature you can grayscale multiple regions.
