Detailed Description

Memory stream buffer used with TIFFClientOpen()

The L_Memstram buffer has different functions in writing and reading.

• In reading, it is assigned to the data and read from as the tiff library uncompresses the data and generates the pix. The offset points to the current read position in the data, and the hw always gives the number of bytes of data. The outdata and outsize ptrs are not used. When finished, tiffCloseCallback() simply frees the L_Memstream.
• In writing, it accepts the data that the tiff library produces when a pix is compressed. the buffer points to a malloced area of bufsize bytes. The current writing position in the buffer is offset and the most ever written is hw. The buffer is expanded as necessary. When finished, tiffCloseCallback() assigns the outdata and outsize ptrs to the buffer and bufsize results, and frees the L_Memstream.
