Grayscale¶
Here are some examples for making an image grayscale on-the-fly.
Original Image¶

Default Grayscale¶
Using the i_o_gray
url command modifier you can make your images grayscale on-the-fly.
i_o_gray

Manual Selection Grayscale¶
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.
Using i_c_x
and i_c_y
you can set the center of the rectangle and using i_h
and 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.
i_c_x_100,i_c_y_300,i_h_200,i_w_200,i_o_gray

Objects Grayscale¶
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.
i_c_object_car,i_o_gray

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.
