# TIFFReadEncodedStrip

## Synopsis

    #include <tiffio.h>

tmsize_t TIFFReadEncodedStrip(TIFF *tif, uint32_t strip, void *buf, tmsize_t size)

## Description

Read the specified strip of data and place up to size bytes of decompressed information in the (user supplied) data buffer.

## Notes

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). To read a full strip of data the data buffer should typically be at least as large as the number returned by `TIFFStripSize()`. If -1 is passed in the size parameter, the whole strip will be read. You should be sure you have enough space allocated for the buffer.

The library attempts to hide bit- and byte-ordering differences between the image and the native machine by converting data to the native machine order. Bit reversal is done if the `FillOrder` tag is opposite to the native machine bit order. 16- and 32-bit samples are automatically byte-swapped if the file was written with a byte order opposite to the native machine byte order.

## Return values

The actual number of bytes of data that were placed in buf is returned; `TIFFReadEncodedStrip()` returns -1 if an error was encountered.

## Diagnostics

All error messages are directed to the `TIFFErrorExtR()` routine.
