Camera handle
DR_DISABLE_SEMI_TRANSPARENT_OVERLAY
Disables the semi-transparent display of the overlay
area. Example
DR_SET_VSYNC_AUTO
Enables synchronization of the image display with the
monitor's image rendering. The image is displayed upon
the monitor's next VSYNC signal. Example
DR_SET_VSYNC_OFF
Disables image display synchronization. The image is
displayed immediately. Example
DR_SET_USER_SYNC
Direct3D only: Enables synchronization of the image
display with a monitor pixel row specified by the user.
More details
When displaying very large camera images, the auto
VSYNC function might not always optimally synchronize
image rendering. In this case, you can eliminate flicker by
manually setting a suitable position for synchronization.
The position needs to be determined individually, based
on the camera type and the graphics card.
Example
DR_GET_USER_SYNC_POSITION_RANGE
Direct3D only: Returns the minimum and maximum row
position for DR_SET_USER_SYNC. Example
DR_LOAD_OVERLAY_FROM_FILE
Direct3D only: Loads a bitmap image (*.BMP file) into the
overlay area. If the bitmap image is larger than the overlay
area, the bitmap image is clipped. Example
DR_CLEAR_OVERLAY
Deletes the data of the overlay area by filling it with black
color. Example
DR_STEAL_NEXT_FRAME
Copies the next image to the active user memory (Steal
function).
More details
Using the pParam parameter, you specify when the
function should return:
IS_WAIT: The function waits until the image save is
complete.
IS_DONT_WAIT: The function returns immediately.
Example
DR_SET_STEAL_FORMAT
Defines the color format for the Steal function.
More details
For a list of all available color formats, see the function
description for is_SetColorMode() . The default is
IS_CM_BGRA8_PACKED (RGB 32).
Example
DR_GET_STEAL_FORMAT
Returns the color format setting for the Steal function.
Example
DR_SET_HWND
Sets a new window handle for image output in Direct3D.
Example
DR_CHECK_COMPATIBILITY
Returns whether the graphics card supports the uc480
Direct3D functions. Example
DR_GET_OVERLAY_DATA
OpenGL only: Returns a pointer to the overlay.
DR_UPDATE_OVERLAY_DATA
OpenGL only: Updates the overlay.
pParam
Pointer to a function parameter, whose function depends
on nCommand.
nSize
Size (in bytes) of the data object or array.
