Syntax
INT is_SetSensorScaler (HIDS hCam, UINT nMode, double dblFactor)
Description
is_SetSensorScaler() enables internal image scaling for some sensors. This allows to reduce the image resolution by adjustable factors. Thus, the amount of data from high resolution sensors can be reduced.
|
Internal image scaling is only supported by UI-149x/UI-549x, UI-124x/UI-324x/UI-524x and UI-125x/UI-325x/UI-525x series sensors. |
|
The use of the internal scaler has no effect on the attainable frame rate on the UI-149x/UI-549x models. |
Input parameters

Return values
IS_CANT_COMMUNICATE_WITH_DRIVER |
Communication with the driver failed because no driver has been loaded. |
IS_CANT_OPEN_DEVICE |
An attempt to initialize or select the camera failed (no camera connected or initialization error). |
IS_INVALID_CAMERA_TYPE |
The camera type defined in the .ini file does not match the current camera model. |
IS_INVALID_CAMERA_HANDLE |
Invalid camera handle |
IS_INVALID_PARAMETER |
One of the submitted parameters is outside the valid range or is not supported for this sensor or is not available in this mode. |
IS_IO_REQUEST_FAILED |
An IO request from the uEye driver failed. Possibly the versions of the ueye_api.dll (API) and the driver file (ueye_usb.sys or ueye_eth.sys) do not match. |
IS_NO_SUCCESS |
General error message |
IS_NOT_CALIBRATED |
The camera does not contain any calibration data. |
IS_NOT_SUPPORTED |
The camera model used here does not support this function or setting. |
IS_NULL_POINTER |
Invalid array |
IS_SUCCESS |
Function executed successfully |
IS_TIMED_OUT |
A timeout occurred. An image capturing process could not be terminated within the allowable period. |

Example
SENSORSCALERINFO Info;
INT nRet;
double dblNewFactor;
// Query information on image scaling
nRet = is_GetSensorScalerInfo (hCam, &Info, sizeof(Info));
// Enable scaling with anti aliasing
dblNewFactor = Info.dblMinFactor + Info.dblFactorIncrement;
nRet = is_SetSensorScaler (hCam, IS_ENABLE_SENSOR_SCALER | IS_ENABLE_ANTI_ALIASING, dblNewFactor);
// Disable scaling with anti aliasing
dblNewFactor = 0.0;
nRet = is_SetSensorScaler (hCam, IS_DISABLE_SENSOR_SCALER, dblNewFactor);
