Syntax
INT is_SetScaler (HIDS hf, float scalex, float scaley)
Description
With is_SetScaler() the scaler is activated/deactivated and at same time the horizontal and vertical scaling factor is provided. The scaler works with scaling factors from 16 % to 100 % on the horizontal and vertical axis. With a built in interpolation filter, undesired distortion in the image is kept to a minimum. For post acquisition image processing we recommend that the scaler is turned off.
Is the image to be reduced from full-size, first of all the desired image size must be set with function is_SetImageSize(). Afterwards the scaler is activated with is_SetScaler(hf, IS_SET_SCALER_ON, IS_SET_SCALER_ON);.
