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 alot of the loop - * overhead of the byte-by-bye 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 - * routine. So user beware, you have been warned! - */ - -#define EXP_ASCII85ENCODER - -/* - * NB: this code assumes uint32 works with printf's %l[ud]. - */ - -struct _TIFF2PSContext -{ - char *filename; /* input filename */ - FILE *fd; /* output file stream */ - int ascii85; /* use ASCII85 encoding */ - int interpolate; /* interpolate level2 image */ - int level2; /* generate PostScript level 2 */ - int level3; /* generate PostScript level 3 */ - int generateEPSF; /* generate Encapsulated PostScript */ - int PSduplex; /* enable duplex printing */ - int PStumble; /* enable top edge binding */ - int PSavoiddeadzone; /* enable avoiding printer deadzone */ - double maxPageHeight; /* maximum size to fit on page */ - double splitOverlap; /* amount for split pages to overlag */ - int rotate; /* rotate image by 180 degrees */ - int useImagemask; /* Use imagemask instead of image operator */ - uint16 res_unit; /* Resolution units: 2 - inches, 3 - cm */ - int npages; /* number of pages processed */ - - tsize_t tf_bytesperrow; - tsize_t ps_bytesperrow; - tsize_t tf_rowsperstrip; - tsize_t tf_numberstrips; - - /* - * ASCII85 Encoding Support. - */ - unsigned char ascii85buf[10]; - int ascii85count; - int ascii85breaklen; - uint16 samplesperpixel; - uint16 bitspersample; - uint16 planarconfiguration; - uint16 photometric; - uint16 compression; - uint16 extrasamples; - int alpha; -}; - -static void PSpage(TIFF2PSContext*, TIFF*, uint32, uint32); -static void PSColorContigPreamble(TIFF2PSContext*, uint32, uint32, int); -static void PSColorSeparatePreamble(TIFF2PSContext*, uint32, uint32, int); -static void PSDataColorContig(TIFF2PSContext*, TIFF*, uint32, uint32, int); -static void PSDataColorSeparate(TIFF2PSContext*, TIFF*, uint32, uint32, int); -static void PSDataPalette(TIFF2PSContext*, TIFF*, uint32, uint32); -static void PSDataBW(TIFF2PSContext*, TIFF*, uint32, uint32); -static void Ascii85Init(TIFF2PSContext*); -static void Ascii85Put(TIFF2PSContext*, unsigned char); -static void Ascii85Flush(TIFF2PSContext*); -static void PSHead(TIFF2PSContext*, TIFF*, uint32, uint32, - double, double, double, double); -static void PSTail(TIFF2PSContext*); - -#if defined( EXP_ASCII85ENCODER ) -static int Ascii85EncodeBlock(TIFF2PSContext*, uint8 * ascii85_p, - unsigned f_eod, const uint8 * raw_p, int raw_l); -#endif - -TIFF2PSContext* tiff2ps_context_new(const gchar *filename) { - TIFF2PSContext* ctx; - - ctx = g_new0(TIFF2PSContext, 1); - ctx->filename = g_strdup(filename); - ctx->fd = g_fopen(ctx->filename, "w"); - if (ctx->fd == NULL) - return NULL; - ctx->interpolate = TRUE; /* interpolate level2 image */ - ctx->PSavoiddeadzone = TRUE; /* enable avoiding printer deadzone */ - return ctx; -} - -void tiff2ps_context_finalize(TIFF2PSContext *ctx) { - PSTail(ctx); - fclose(ctx->fd); - g_free(ctx->filename); - g_free(ctx); -} - -static int -checkImage(TIFF2PSContext *ctx, TIFF* tif) -{ - switch (ctx->photometric) { - case PHOTOMETRIC_YCBCR: - if ((ctx->compression == COMPRESSION_JPEG - || ctx->compression == COMPRESSION_OJPEG) - && ctx->planarconfiguration == PLANARCONFIG_CONTIG) { - /* can rely on libjpeg to convert to RGB */ - TIFFSetField(tif, TIFFTAG_JPEGCOLORMODE, - JPEGCOLORMODE_RGB); - ctx->photometric = PHOTOMETRIC_RGB; - } else { - if (ctx->level2 || ctx->level3) - break; - TIFFError(ctx->filename, "Can not handle image with %s", - "Ctx->PhotometricInterpretation=YCbCr"); - return (0); - } - /* fall thru... */ - case PHOTOMETRIC_RGB: - if (ctx->alpha && ctx->bitspersample != 8) { - TIFFError(ctx->filename, - "Can not handle %d-bit/sample RGB image with ctx->alpha", - ctx->bitspersample); - return (0); - } - /* fall thru... */ - case PHOTOMETRIC_SEPARATED: - case PHOTOMETRIC_PALETTE: - case PHOTOMETRIC_MINISBLACK: - case PHOTOMETRIC_MINISWHITE: - break; - case PHOTOMETRIC_LOGL: - case PHOTOMETRIC_LOGLUV: - if (ctx->compression != COMPRESSION_SGILOG && - ctx->compression != COMPRESSION_SGILOG24) { - TIFFError(ctx->filename, - "Can not handle %s data with ctx->compression other than SGILog", - (ctx->photometric == PHOTOMETRIC_LOGL) ?
