ImageFormatControl_C.c

ImageFormatControl_C.c shows how to apply custom image settings to the camera. It relies on information provided in the Enumeration_C, Acquisition_C, and NodeMapInfo_C examples.

This example demonstrates setting minimums to offsets, X and Y, and maximums to width and height. It also shows the setting of a new pixel format, which is an enumeration type node.

Following this, we suggest familiarizing yourself with the Exposure_C example if you haven't already. Exposure is another example on camera customization that is shorter and simpler than many of the others. Once comfortable with Exposure_C and ImageFormatControl_C, we suggest checking out any of the longer, more complicated examples related to camera configuration: ChunkData_C, LookupTable_C, Sequencer_C, or Trigger_C.
