Name | Type | Description |
---|---|---|
hIGear | HIGEAR | HIGEAR handle of the image to which you wish make the non-rectangular ROI setting changes. |
nAttributeID | AT_MODE | Set to an AT_MODE constant for the non-rectangular ROI attribute you would like to set. |
lpData | const LPVOID | Set to the desired attribute setting. |
Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.
This function does not process image pixels.

AT_ERRCOUNT nErrcount; HIGEAR hIGear; BOOL bCondition; HIGEAR hIGearMask;] /* Find out whether the image rectangle for hIGear is set to be overridden by a non- rectangular ROI */ nErrcount = IG_IP_NR_ROI_control_set (hIGear, IG_CONTROL_NR_ROI_DIB, (LPVOID) hIGearMask); /* Find out what the reference point for a mask HIGEAR is in the hIGear */ nErrcount = IG_IP_NR_ROI_control_set (hIGear, IG_CONTROL_NR_ROI_CONDITION, (LPVOID) bCondition); |
These attributes are only applicable for non-rectangular ROIs. Use IG_IP_NR_ROI_to_HIGEAR_mask() to create the mask image.
All ROI control settings have defined constants in accucnst.h which have a prefix of IG_CONTROL_NR_ROI_. The following is a list of each setting available at the time of this writing, and a description of what each does.
