Syntax
INT is_ImageFormat (HIDS hCam,
UINT nCommand,
void *pParam,
UINT nSizeOfParam)
Description
Using is_ImageFormat(), you can query a list of possible image sizes and set a new image format if supported
by your DCx Camera model. This is useful for sensors that do not support a free selection of the area of interest or
image format. Using the AOI, binning/subsampling or scaling functions, the driver sets the selected image format to
achieve the best possible image quality. For a complete list of available image formats see table "Image formats"
below.
The nCommand input parameter is used to select the function mode. The pParam input parameter depends on the
selected function mode. If you select functions for setting or returning a value, pParam contains a pointer to a
variable of the UINT type. The size of the memory area to which pParam refers is specified in the nSizeOfParam
input parameter.
