<XSI_Image>

Stores information about a specific image used in the scene.

((EDITOR: This page needs the following improvement: Why do the member names given here not match what's in the example? For example, in table it's "channel_count"; in example, it's "NumChannels". ))

Member Description
FileName Name of source file.
SizeX Image size in X.
SizeY Image size in Y.
NumChannels Number of channels. Possible values are:
  • 3: RGB
  • 4: RGBA
BitsPerPixel Number of bits per pixel. Possible values:
  • 24
  • 32
CropMinX Leftmost X of the cropping rectangle.
CropMaxX Rightmost X of the cropping rectangle.
CropMinY Leftmost Y of the cropping rectangle.
CropMaxY Rightmost Y of the cropping rectangle.
FrameRate Frame rate to use. If this value is 0, the scene frame rate is assumed; otherwise, this value is the new frame rate.
NumberOfFrames Number of frames for sequence.
FirstFrame Frame number for first frame in sequence.
LastFrame Frame number for last frame in sequence.
