SetDSequenceAccuracy
The SetDSequenceAccuracy function adjusts the decompression accuracy for the current sequence.
pascal OSErr SetDSequenceAccuracy (ImageSequence seqID,
CodecQ accuracy);
seqID
- Contains the unique sequence identifier that was returned by the
DecompressSequenceBegin function (described on page 3-107).
accuracy
- Specifies the accuracy desired in the decompressed image. Values for this parameter are on the same scale as compression quality. See "Compression Quality Constants" beginning on page 3-57, for available values.
DESCRIPTION
The accuracy parameter governs how precisely the decompressor decompresses the image data. Some decompressors may choose to ignore some image data to improve decompression speed. A new accuracy parameter takes effect with the next frame in the sequence.
RESULT CODES
| noErr | 0 | No error |
| paramErr | -50 | Invalid parameter specified |
SEE ALSO
You set the default accuracy value for a sequence with the accuracy parameter to the DecompressSequenceBegin function.
