DeepImage
This object allows the manipulation of the DeepPixel data contained within this image object.

Look up the pixel's interpolated value at depth z, and put the result in data. Data must point at float storage large enough to encompass the number of channels in the image.

Computes the mean depth found in the pixel and the overall coverage. This is useful for displaying deep images.

Get a handle to the image-specific metadata. May be null on older files.
| virtual const char* RixDeepTexture::DeepImage::GetName |

return the name of this image. The resulting pointer is guaranteed to be valid until DtexClose() is called on the containing file.

DeepPixel * |

) |
| |
|
pure virtual |
Copy the pixel at position x,y into the given DeepPixel. The DeepPixel is resized if necessary, and if the number of channels in pix is different than the number of channels in this image, pix is modified to match. Returns k_ErrNOERR if no error, k_ErrRANGE if the requested pixel outside the image, or k_ErrBADFILE if the file is found to be corrupt.

|
pure virtual |
Computes the range over which the specified pixel is defined. If the pixel is non-empty, the range is returned in min and max and the function returns k_ErrNOERR. If the pixel is empty, k_ErrEMPTY is returned and min and max are undefined.

|
DeepPixel * |
pix |
|
) |
| |
|
pure virtual |
Copy the given pixel into pixel x,y of the specified image. pix must have either the same number of channels as img, or one channel. If pix has any unresolved compression state, k_ErrERR is returned. Take care to call pix->FinishPixel before you use SetPixel.

| |
|
pure virtual |
Copy the given pixel data into pixel x, y of the specified image. numPoints indicates how many points there are. data should point to numPoints*(GetNumChan()+1) floats.
