info_framegrabber ( : : : Width, Height, Bits, ColorSpaces, PixelRatios, Full, Explain )
Return possible operational modes of the current framegrabber.
The operator info_framegrabber returns the possible operational modes of
the currently open framegrabber. An operational mode is characterized as
follows:
Width, Height Resolution of framegrabber.
Bits Number of bits per pixel (1 bit: S/W,
8 bit: grayvalues, 24 bit: color).
ColorSpaces For colored images only: color space (typically
'rgb').
PixelRatios Side ratio (width / height) of the pixels.
Full Full image ('true') or half image ('false').
The desired operational mode can be adjusted via open_framegrabber
The parameter Explain contains a text explaining the framegrabber
specific generc parameter Generic of open_framegrabber.
