getImType
|
|
Image
|
|
An integer between 0 and 116 specifying the frame number of the image. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.
|
|
|
The type of the image. Can be one of the following values:
|
|
IM_GRAY or IM_GRAY8 8-bit grayscale image (256 levels)
|
IM_1BIT 1-bit palettized image (2 colors)
|
IM_4BIT 4-bit palettized image (16 colors)
|
IM_8BIT 8-bit palettized image (256 colors)
|
IM_MULTI multiphase image (256 bands)
|
IM_RGB16 16-bit high-color image (5-bit x 3 channels, 32768 colors)
|
IM_RGB24 or IM_RGB 24-bit true-color image (8-bit x 3 channels, 16777216 colors)
|
IM_RGB32 32-bit true-color image (8-bit x 3 + alpha channel, 16777216 colors)
|
IM_RGB48 48-bit true-color image (16-bit x 3 channels, 281 trillion colors)
|
IM_GRAY16 16-bit grayscale image (65536 levels)
|
IM_GRAY32 32-bit grayscale image (4294967296 levels)
|
IM_FLOAT 32-bit floating point image
|
IM_COMPLEX 64 bit complex image (32-bit floating point x 2 channels)
|
|
ERR_OK
|
|
The flag set if successful.
|
|
ERR_FAILED
|
|
The flag set if failed.
|
|
This set of statements retrieves the type a captured image and checks whether it is a 16-bit grayscale image:
|
|
grabIm (1)
|
type=getImType (1)
|
if type=IM_GRAY16 THEN print "16-bit grayscale"
