TIFFWriteEncodedStrip ===================== Synopsis -------- .. highlight:: c :: #include .. c:function:: tsize_t TIFFWriteEncodedStrip(TIFF* tif, tstrip_t strip, tdata_t buf, tsize_t size) Description ----------- Compress *size* bytes of raw data from *buf* and write the result to the specified strip; replacing any previously written data. Note that the value of *strip* is a "raw strip number". That is, the caller must take into account whether or not the data are organized in separate planes (``PlanarConfiguration`` = 2). Notes ----- The library writes encoded data using the native machine byte order. Correctly implemented TIFF readers are expected to do any necessary byte-swapping to correctly process image data with ``BitsPerSample`` greater than 8. The strip number must be valid according to the current settings of the ``ImageLength`` and ``RowsPerStrip`` tags. An image may be dynamically grown by increasing the value of ``ImageLength`` prior to each call to ``TIFFWriteEncodedStrip``. Return values ------------- -1 is returned if an error was encountered. Otherwise, the value of *size* is returned. Diagnostics ----------- All error messages are directed to the :c:func:`TIFFErrorExtR` routine. ``%s: File not open for writing``: The file was opened for reading, not writing. ``Can not write scanlines to a tiled image``: The image is assumed to be organized in tiles because the ``TileWidth`` and ``TileLength`` tags have been set with :c:func:`TIFFSetField`. ``%s: Must set "ImageWidth" before writing data\fP``: The image's width has not be set before the first write. See :c:func:`TIFFSetField` for information on how to do this. ``%s: Must set "PlanarConfiguration" before writing data``: The organization of data has not be defined before the first write. See :c:func:`TIFFSetField` for information on how to do this. ``%s: No space for strip arrays"``: There was not enough space for the arrays that hold strip offsets and byte counts.
