/* output.h - Common routines for raster/vector
libzint - the open source barcode library
- raster.c: Need ceilf(symbol->height * si) to avoid heap-buffer-overflow; also avoid distributive multiplication with floats to lessen chances of platform variation (#204 ARM-Cortex crash) - raster.c: Don't allow for text if scale < 1.0 - raster.c: Cast some indexes to (size_t) to allow for large scale - vector.c: Check malloc()s and return ZINT_ERROR_MEMORY on fail - raster/vector.c: various var name changes & other code fiddling - library.c: Check that scale/height/whitespace/border are reasonable values: scale (0.01-100), height (0-500), whitespace_width/height (0-100), border_width (0-100) - CLI: allow both e.g. '-height' and '--height' (getopt_long_only()) - gif.c: fix GIF_ZLW_PAGE_SIZE -> GIF_LZW_PAGE_SIZE - GUI: allow whitespace/scale to 100

Performance improvements for linear encoding and raster output - use fixed-length string tables (mostly) instead of (char *) pointer ones (saves ~40K) - re-use C128Table for CODABLOCKF and CODE16K (required removal of Stop character and extra CODE16K-only entry) - use pointer to destination and copy (memcpy/strcpy(), bin_append_posn()) instead of concatenating (strcat()) (mostly) - replace last remaining bin_append()s with bin_append_posn(); bin_append() removed - add length arg to toupper() and expand() (avoids strlen()) - change is_sane() to use table-based flags (avoids an iteration) - rename lookup() to is_sane_lookup() and change to check and return posns and use in pointer to destination loops (avoids strcat()s) - remove special case PHARMA in expand() (dealt with in pharma()) - make #define SILVER/CALCIUM/TECHNETIUM/KRSET etc static strings - replace strchr() -> posn() - CODE128: populate destination once in checksum loop; re-use and export some more routines (c128_set_a/b/c(), c128_put_in_set()) for sharing; prefix defines (SHIFTA -> C128_SHIFTA etc) and existing exported routines - use factor XOR toggle trick in checksum calcs (avoids branch) - raster.c: fill out single 1-pixel row and copy using new draw_bar_line(), copy_bar_line() routines; similarly in buffer_plot compare previous line & copy if same (same technique as used to improve non-half-integer scaling, significant performance increase, (c) codemonkey82); also done for PNG (BMP/GIF/PCX/TIFF not done) - raster/vector/output.c: shorten "output_" prefix -> "out_"; sync vector to other raster changes to try to keep source files similar - 2of5.c: prefix "c25_" JAPANPOST: return error if input data truncated (backward incompatible) DAFT: max chars 50 -> 100 common.c: istwodigit() -> is_twodigit() common.c/emf.c/output.c: use some further stripf()s (MSVC6 float variations) library.c: new check_output_args() helper zint.h: add BARCODE_LAST marker and use in library.c QRCODE: remove a NOLINT (requires clang-tidy-13), one remaining CMake: separate no-optimize from ZINT_DEBUG into new ZINT_NOOPT option
