* Revision history
|
||
*
|
||
* 2010-Sep-17
|
||
* Richard Nolde: Reinstate code from Feb 2009 that never got
|
||
* accepted into CVS with major modifications to handle -H and -W
|
||
* options. Replaced original PlaceImage function with several
|
||
* new functions that make support for multiple output pages
|
||
* from a single image easier to understand. Added additional
|
||
* warning messages for incompatible command line options.
|
||
* Add new command line options to specify PageOrientation
|
||
* Document Structuring Comment for landscape or portrait
|
||
* and code to determine the values from ouput width and height
|
||
* if not specified on the command line.
|
||
* Add new command line option to specify document creator
|
||
* as an alterntive to the string "tiff2ps" following model
|
||
* of patch submitted by Thomas Jarosch for specifiying a
|
||
* document title which is also supported now.
|
||
*
|
||
* 2009-Feb-11
|
||
* Richard Nolde: Added support for rotations of 90, 180, 270
|
||
* and auto using -r <90|180|270|auto>. Auto picks the best
|
||
* fit for the image on the specified paper size (eg portrait
|
||
* or landscape) if -h or -w is specified. Rotation is in
|
||
* degrees counterclockwise since that is how Postscript does
|
||
* it. The auto opption rotates the image 90 degrees ccw to
|
||
* produce landscape if that is a better fit than portait.
|
||
*
|
||
* Cleaned up code in TIFF2PS and broke into smaller functions
|
||
* to simplify rotations.
|
||
*
|
||
* Identified incompatible options and returned errors, eg
|
||
* -i for imagemask operator is only available for Level2 or
|
||
* Level3 Postscript in the current implmentation since there
|
||
* is a difference in the way the operands are called for Level1
|
||
* and there is no function to provide the Level1 version.
|
||
* -H was not handled properly if -h and/or -w were specified.
|
||
* It should only clip the masked images if the scaled image
|
||
* exceeds the maxPageHeight specified with -H.
|
||
*
|
||
* New design allows for all of the following combinations:
|
||
* Conversion of TIFF to Postscript with optional rotations
|
||
* of 90, 180, 270, or auto degrees counterclockwise
|
||
* Conversion of TIFF to Postscript with entire image scaled
|
||
* to maximum of values spedified with -h or -w while
|
||
* maintaining aspect ratio. Same rotations apply.
|
||
* Conversion of TIFF to Postscript with clipping of output
|
||
* viewport to height specified with -H, producing multiple
|
||
* pages at this height and original width as needed.
|
||
* Same rotations apply.
|
||
* Conversion of TIFF to Postscript with image scaled to
|
||
* maximum specified by -h and -w and the resulting scaled
|
||
* image is presented in an output viewport clipped by -H height.
|
||
* The same rotations apply.
|
||
*
|
||
* Added maxPageWidth option using -W flag. MaxPageHeight and
|
||
* MaxPageWidth are mutually exclusive since the aspect ratio
|
||
* cannot be maintained if you set both.
|
||
* Rewrote PlaceImage to allow maxPageHeight and maxPageWidth
|
||
* options to work with values smaller or larger than the
|
||
* physical paper size and still preserve the aspect ratio.
|
||
* This is accomplished by creating multiple pages across
|
||
* as well as down if need be.
|
||
*
|
||
* 2001-Mar-21
|
||
* I (Bruce A. Mallett) added this revision history comment ;)
|
||
*
|
||
* Fixed PS_Lvl2page() code which outputs non-ASCII85 raw
|
||
* data. Moved test for when to output a line break to
|
||
* *after* the output of a character. This just serves
|
||
* to fix an eye-nuisance where the first line of raw
|
||
* data was one character shorter than subsequent lines.
|
||
*
|
||
* Added an experimental ASCII85 encoder which can be used
|
||
* only when there is a single buffer of bytes to be encoded.
|
||
* This version is much faster at encoding a straight-line
|
||
* buffer of data because it can avoid a lot of the loop
|
||
* overhead of the byte-by-byte version. To use this version
|
||
* you need to define EXP_ASCII85ENCODER (experimental ...).
|
||
*
|
||
* Added bug fix given by Michael Schmidt to PS_Lvl2page()
|
||
* in which an end-of-data marker ('>') was not being output
|
||
* when producing non-ASCII85 encoded PostScript Level 2
|
||
* data.
|
||
*
|
||
* Fixed PS_Lvl2colorspace() so that it no longer assumes that
|
||
* a TIFF having more than 2 planes is a CMYK. This routine
|
||
* no longer looks at the samples per pixel but instead looks
|
||
* at the "photometric" value. This change allows support of
|
||
* CMYK TIFFs.
|
||
*
|
||
* Modified the PostScript L2 imaging loop so as to test if
|
||
* the input stream is still open before attempting to do a
|
||
* flushfile on it. This was done because some RIPs close
|
||
* the stream after doing the image operation.
|
||
*
|
||
* Got rid of the realloc() being done inside a loop in the
|
||
* PSRawDataBW() routine. The code now walks through the
|
||
* byte-size array outside the loop to determine the largest
|
||
* size memory block that will be needed.
|
||
*
|
||
* Added "-m" switch to ask tiff2ps to, where possible, use the
|
||
* "imagemask" operator instead of the "image" operator.
|
||
*
|
||
* Added the "-i #" switch to allow interpolation to be disabled.
|
||
*
|
||
* Unrolled a loop or two to improve performance.

/*
|
||
* Define EXP_ASCII85ENCODER if you want to use an experimental
|
||
* version of the ASCII85 encoding routine. The advantage of
|
||
* using this routine is that tiff2ps will convert to ASCII85
|
||
* encoding at between 3 and 4 times the speed as compared to
|
||
* using the old (non-experimental) encoder. The disadvantage
|
||
* is that you will be using a new (and unproven) encoding

*
|
||
* Name: Ascii85EncodeBlock( ascii85_p, f_eod, raw_p, raw_l )
|
||
*
|
||
* Description: This routine will encode the raw data in the buffer described
|
||
* by raw_p and raw_l into ASCII85 format and store the encoding
|
||
* in the buffer given by ascii85_p.
|
||
*
|
||
* Parameters: ascii85_p - A buffer supplied by the caller which will
|
||
* contain the encoded ASCII85 data.
|
||
* f_eod - Flag: Nz means to end the encoded buffer with
|
||
* an End-Of-Data marker.
|
||
* raw_p - Pointer to the buffer of data to be encoded
|
||
* raw_l - Number of bytes in raw_p[] to be encoded
|
||
*
|
||
* Returns: (int) < 0 Error, see errno
|
||
* >= 0 Number of bytes written to ascii85_p[].
|
||
*
|
||
* Notes: An external variable given by A85BREAKCNTR is used to
|
||
* determine when to insert newline characters into the
|
||
* encoded data. As each byte is placed into ascii85_p this
|
||
* external is decremented. If the variable is decrement to
|
||
* or past zero then a newline is inserted into ascii85_p
|
||
* and the A85BREAKCNTR is then reset to A85BREAKLEN.
|
||
* Note: for efficiency reasons the A85BREAKCNTR variable
|
||
* is not actually checked on *every* character
|
||
* placed into ascii85_p but often only for every
|
||
* 5 characters.
|
||
*
|
||
* THE CALLER IS RESPONSIBLE FOR ENSURING THAT ASCII85_P[] IS
|
||
* SUFFICIENTLY LARGE TO THE ENCODED DATA!
|
||
* You will need at least 5 * (raw_l/4) bytes plus space for
|
||
* newline characters and space for an EOD marker (if
|
||
* requested). A safe calculation is to use 6*(raw_l/4) + 8
|
||
* to size ascii85_p.
