+/* @file plustek-pp_image.c
+ * @brief functions to convert scanner data into image data
+ *
+ * based on sources acquired from Plustek Inc.
+ * Copyright (C) 1998 Plustek Inc.
+ * Copyright (C) 2000-2013 Gerhard Jaeger <gerhard@gjaeger.de>
+ * also based on the work done by Rick Bronson
+ *
+ * History:
+ * - 0.30 - initial version
+ * - 0.31 - no changes
+ * - 0.32 - no changes
+ * - 0.33 - no changes
+ * - 0.34 - reactivated code in imageP96WaitLineData() to recover from
+ * loosing data
+ * - 0.35 - no changes
+ * - 0.36 - removed comment
+ * - added wDither exchange to imageP9xSetupScanSettings
+ * - added fnHalftoneDirect1 which provides dithering by using random
+ * thresholds
+ * - removed the swapping behaviour for model OP_600 in
+ * fnP96ColorDirect() according to the Primax 4800 Direct tests
+ * - changes, due to define renaming
+ * - removed _ASIC_96001 specific stuff to invert colors
+ * - 0.37 - removed // comments
+ * - corrected output of 12bit/pixel
+ * - 0.38 - added P12 stuff
+ * - renamed WaitLineData functions to ReadOneImageLine
+ * - 0.39 - fixed a problem in imageP98003ReadOneImageLine, that causes
+ * these I/O timeouts...
+ * - 0.40 - no changes
+ * - 0.41 - no changes
+ * - 0.42 - fixed a problem for the 12bit modes fo ASIC9800x based devices
+ * - changed include names
+ * - 0.43 - removed floating point stuff
+ * - cleanup
+ * - 0.44 - fix format string issues, as Long types default to int32_t
+ * now
