Setting the Frame Parameters

You can set the Offset X, Width, and Height parameter values from within your application software

by using the pylon API. The following code snippets illustrate using the API to get the maximum

allowed settings and the increments for the Offset X, Width and Height parameters. They also

illustrate setting the Offset X, Width, and Height parameter values.

int64_t offsetxMax = Camera.OffsetX.GetMax( );

int64_t offsetxInc = Camera.OffsetX.GetInc( );

Camera.OffsetX.SetValue( 100 );

int64_t widthMax = Camera.Width.GetMax( );

int64_t widthInc = Camera.Width.GetInc( );

Camera.Width.SetValue( 200 );

int64_t heightMax = Camera.Height.GetMax( );

int64_t heightInc = Camera.Height.GetInc( );

Camera.Height.SetValue( 200 );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about the pylon Viewer, see Section 3.1 on page 23.

The Width and Height parameters cannot be changed while the camera is in the

process of acquiring frames. If the camera receives commands to change the

Width or Height parameter values while it is in the process of acquiring frames:

 If the camera is set for single frame mode, the parameters will not change

until the current frame is complete or you issue an acquisition stop command.

 If the camera is set for continuous frame mode, the parameters will not

change until you issue an acquisition stop command.
