USB 2.0
USB 2.0
Syntax
INT is_SetImageSize (HIDS hCam, INT x, INT y)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_AOI() function
instead (see also Obsolete functions ).
In conjunction with the is_SetImagePos() settings, is_SetImageSize() determines the size of the
captured area of interest (AOI).
To avoid a positional mismatch between the display area and the image area, make sure to call the functions in the
correct order. Starting from the original image, it is mandatory to keep to the following order:
1.is_SetImageSize()
2.is_SetImagePos()
Hint
is_SetAOI() combines both functions. With is_SetAOI(), you can set the position and size of an area of
interest using a single function call.
Note
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and exposure time. After
executing is_SetImageSize(), calling the following functions is recommended in order to keep the defined
camera settings:
is_SetFrameRate()
is_Exposure()
If you are using the DCx Camera's flash function: is_IO()
