gitlost ab2abccdb6 - zint_symbol->fgcolour & bgcolour buffer lengths extended 10 
-> 16 to allow for "C,M,Y,K" comma-separated decimal percentage
  strings
- API/CLI/GUI: allow foreground/background colours to be specified
  as comma-separated decimal "C,M,Y,K" strings where "C", "M" etc.
  are percentages (0-100) (ticket #281, 3rd point)
- output.c: new funcs `out_colour_get_rgb()` & `out_colour_get_cmyk()`
  and use in bmp/emf/gif etc.
- PCX: add alpha support
- GUI: fix fg/gbcolor icon background not being reset on zap
- GUI: Rearrange some Appearance tab inputs (Border Type <-> Width,
  Show Text <-> Font, Text/Font <-> Printing Scale/Size) to flow
  more naturally (hopefully)
- GUI: save button "Save As..." -> "Save..." and add icon
- CLI: add --bgcolor/colour & --fgcolor/colour synonyms

# NAME
`zint` - encode data as a barcode image
# SYNOPSIS
| `zint` [`-h` | `--help`]
| `zint` [*options*]
# DESCRIPTION
zint takes input data from the command line or a file to encode in a barcode which is then output to an image file.
Input data is UTF-8, unless `--binary` is specified.
Human Readable Text (HRT) is displayed by default for those barcodes that support HRT, unless `--notext` is specified.
The output image file (specified with `-o` | `--output`) may be in one of these formats: Windows Bitmap (`BMP`),
Enhanced Metafile Format (`EMF`), Encapsulated PostScript (`EPS`), Graphics Interchange Format (`GIF`), ZSoft
Paintbrush (`PCX`), Portable Network Format (`PNG`), Scalable Vector Graphic (`SVG`), or Tagged Image File Format
(`TIF`).
# OPTIONS
`-h`, `--help`
: Print usage information summarizing command line options.
`-b TYPE`, `--barcode=TYPE`
: Set the barcode symbology that will be used to encode the data. *TYPE* is the number or name of the barcode
symbology. If not given, the symbology defaults to 20 (Code 128). To see what types are available, use the `-t` |
`--types` option. Type names are case-insensitive, and non-alphanumerics are ignored.
`--addongap=INTEGER`
: For EAN/UPC symbologies, set the gap between the main data and the add-on. *INTEGER* is in integral multiples of
the X-dimension. The maximum gap that can be set is 12. The minimum is 7, except for UPC-A, when the minimum is 9.
`--batch`
: Treat each line of an input file specified with `-i` | `--input` as a separate data set and produce a barcode
image for each one. The barcode images are outputted by default to numbered filenames starting with "00001.png",
"00002.png" etc., which can be changed by using the `-o` | `--output` option.
`--bg=COLOUR`
: Specify a background (paper) colour where *COLOUR* is in hexadecimal `RRGGBB` or `RRGGBBAA` format or in decimal
`C,M,Y,K` percentages format.
`--binary`
: Treat input data as raw 8-bit binary data instead of the default UTF-8. Automatic code page translation to an ECI
page is disabled, and no validation of the data's character encoding takes place.
`--bind`
: Add horizontal boundary bars (also known as bearer bars) to the symbol. The width of the boundary bars is
specified by the `--border` option. `--bind` can also be used to add row separator bars to symbols stacked with
multiple `-d` | `--data` inputs, in which case the width of the separator bars is specified with the `--separator`
option.
`--bindtop`
: Add a horizontal boundary bar to the top of the symbol. The width of the boundary bar is specified by the
`--border` option.
`--bold`
: Use bold text for the Human Readable Text (HRT).
`--border=INTEGER`
: Set the width of boundary bars (`--bind` or `--bindtop`) or box borders (`--box`), where *INTEGER* is in integral
multiples of the X-dimension. The default is zero.
`--box`
: Add a box around the symbol. The width of the borders is specified by the `--border` option.
`--cmyk`
: Use the CMYK colour space when outputting to Encapsulated PostScript (EPS) or TIF files.
`--cols=INTEGER`
: Set the number of data columns in the symbol to *INTEGER*. Affects Codablock-F, DotCode, GS1 DataBar Expanded
Stacked (DBAR_EXPSTK), MicroPDF417 and PDF417 symbols.
`--compliantheight`
: Warn if the height specified by the `--height` option is not compliant with the barcode's specification, or if
`--height` is not given, default to the height specified by the specification (if any).
`-d`, `--data=DATA`
: Specify the input *DATA* to encode. The `--esc` option may be used to enter non-printing characters using escape
sequences. The *DATA* should be UTF-8, unless the `--binary` option is given, in which case it can be anything.
`--direct`
: Send output to stdout, which in most cases should be re-directed to a pipe or a file. Use `--filetype` to specify
output format.
`--dmre`
: For Data Matrix symbols, allow Data Matrix Rectangular Extended (DMRE) sizes when considering automatic sizes.
`--dotsize=NUMBER`
: Set the radius of the dots in dotty mode (`--dotty`). *NUMBER* is in multiples of the X-dimension, and may be
floating-point. The default is 0.8.
`--dotty`
: Use dots instead of squares for matrix symbols. DotCode is always in dotty mode.
`--dump`
: Dump a hexadecimal representation of the symbol's encodation to stdout. The same representation may be outputted
to a file by using a `.txt` extension with `-o` | `--output` or by specifying `--filetype=txt`.
`-e`, `--ecinos`
: Display the table of ECIs (Extended Channel Interpretations).
`--eci=INTEGER`
: Set the ECI code for the input data to *INTEGER*. See `-e` | `--ecinos` for a list of the ECIs available. ECIs are
supported by Aztec Code, Code One, Data Matrix, DotCode, Grid Matrix, Han Xin Code, MaxiCode, MicroPDF417, PDF417,
QR Code, rMQR and Ultracode.
`--esc`
: Process escape characters in the input data. The escape sequences are:
\0 (0x00) NUL Null character
\E (0x04) EOT End of Transmission
\a (0x07) BEL Bell
\b (0x08) BS Backspace
\t (0x09) HT Horizontal Tab
\n (0x0A) LF Line Feed
\v (0x0B) VT Vertical Tab
\f (0x0C) FF Form Feed
\r (0x0D) CR Carriage Return
\e (0x1B) ESC Escape
\G (0x1D) GS Group Separator
\R (0x1E) RS Record Separator
\\ (0x5C) \ Backslash
\dNNN (NNN) Any 8-bit character where NNN is
decimal (000-255)
\oNNN (0oNNN) Any 8-bit character where NNN is
octal (000-377)
\xNN (0xNN) Any 8-bit character where NN is
hexadecimal (00-FF)
\uNNNN (U+NNNN) Any 16-bit Unicode BMP character
where NNNN is hexadecimal
\UNNNNNN (U+NNNNNN) Any 21-bit Unicode character
where NNNNNN is hexadecimal
`--extraesc`
: Process the special escape sequences `\^A`, `\^B` and `\^C` that allow manual switching of Code Sets (Code 128
only). The sequence `\^^` can be used to encode data that contains special escape sequences.
`--fast`
: Use faster if less optimal encodation or other shortcuts (affects Data Matrix, MicroPDF417, PDF417, QRCODE & UPNQR
only).
`--fg=COLOUR`
: Specify a foreground (ink) colour where *COLOUR* is in hexadecimal `RRGGBB` or `RRGGBBAA` format or in decimal
`C,M,Y,K` percentages format.
`--filetype=TYPE`
: Set the output file type to *TYPE*, which is one of `BMP`, `EMF`, `EPS`, `GIF`, `PCX`, `PNG`, `SVG`, `TIF`, `TXT`.
`--fullmultibyte`
: Use the multibyte modes of Grid Matrix, Han Xin and QR Code for non-ASCII data.
`--gs1`
: Treat input as GS1 compatible data. Application Identifiers (AIs) should be placed in square brackets `"[]"` (but
see `--gs1parens`).
`--gs1nocheck`
: Do not check the validity of GS1 data.
`--gs1parens`
: Process parentheses `"()"` as GS1 AI delimiters, rather than square brackets `"[]"`. The input data must not
otherwise contain parentheses.
`--gssep`
: For Data Matrix in GS1 mode, use `GS` (0x1D) as the GS1 data separator instead of `FNC1`.
`--guarddescent=NUMBER`
: For EAN/UPC symbols, set the height the guard bars descend below the main bars, where *NUMBER* is in multiples of
the X-dimension. *NUMBER* may be floating-point.
`--height=NUMBER`
: Set the height of the symbol in multiples of the X-dimension. *NUMBER* may be floating-point.
`--heightperrow`
: Treat height as per-row. Affects Codablock-F, Code 16K, Code 49, GS1 DataBar Expanded Stacked (DBAR_EXPSTK),
MicroPDF417 and PDF417.
`-i`, `--input=FILE`
: Read the input data from *FILE*.
`--init`
: Create a Reader Initialisation (Programming) symbol.
`--mask=INTEGER`
: Set the masking pattern to use for DotCode, Han Xin or QR Code to *INTEGER*, overriding the automatic selection.
`--mirror`
: Use the batch data to determine the filename in batch mode (`--batch`). The `-o` | `--output` option can be used
to specify an output directory (any filename will be ignored).
`--mode=INTEGER`
: For MaxiCode and GS1 Composite symbols, set the encoding mode to *INTEGER*.
For MaxiCode (SCM is Structured Carrier Message, with 3 fields: postcode, 3-digit ISO 3166-1 country code, 3-digit
service code):
2 SCM with 9-digit numeric postcode
3 SCM with 6-character alphanumeric postcode
4 Enhanced ECC for the primary part of the message
5 Enhanced ECC for all of the message
6 Reader Initialisation (Programming)
For GS1 Composite symbols (names end in `_CC`, i.e. EANX_CC, GS1_128_CC, DBAR_OMN_CC etc.):
1 CC-A
2 CC-B
3 CC-C (GS1_128_CC only)
`--nobackground`
: Remove the background colour (EMF, EPS, GIF, PNG, SVG and TIF only).
`--noquietzones`
: Disable any quiet zones for symbols that define them by default.
`--notext`
: Remove the Human Readable Text (HRT).
`-o`, `--output=FILE`
: Send the output to *FILE*. When not in batch mode, the default is "out.png" (or "out.gif" if zint built without
PNG support). When in batch mode (`--batch`), special characters can be used to format the output filenames:
~ Insert a number or 0
# Insert a number or space
@ Insert a number or * (+ on Windows)
Any other Insert literally
`--primary=STRING`
: For MaxiCode, set the content of the primary message. For GS1 Composite symbols, set the content of the linear
symbol.
`--quietzones`
: Add compliant quiet zones for symbols that specify them. This is in addition to any whitespace specified by `-w` |
`--whitesp` or `--vwhitesp`.
`-r`, `--reverse`
: Reverse the foreground and background colours (white on black). Known as "reflectance reversal" or "reversed
reflectance".
`--rotate=INTEGER`
: Rotate the symbol by *INTEGER* degrees, where *INTEGER* can be 0, 90, 270 or 360.
`--rows=INTEGER`
: Set the number of rows for Codablock-F or PDF417 to *INTEGER*. It will also set the minimum number of rows for
Code 16K or Code 49, and the maximum number of rows for GS1 DataBar Expanded Stacked (DBAR_EXPSTK).
`--scale=NUMBER`
: Adjust the size of the X-dimension. *NUMBER* may be floating-point, and is multiplied by 2 (except for MaxiCode)
before being applied. The default scale is 1.
For MaxiCode, the scale is multiplied by 10 for raster output, by 40 for EMF output, and by 2 otherwise.
Increments of 0.5 (half-integers) are recommended for non-MaxiCode raster output (BMP, GIF, PCX, PNG and TIF).
See also `--scalexdimdp` below.
`--scalexdimdp=X[,R]`
: Scale the image according to X-dimension *X* and resolution *R*, where *X* is in mm and *R* is in dpmm (dots per
mm). *X* and *R* may be floating-point. *R* is optional and defaults to 12 dpmm (approximately 300 dpi).
The scaling takes into account the output filetype, and deals with all the details mentioned above. Units may be
specified for *X* by appending "in" (inch) or "mm", and for *R* by appending "dpi" (dots per inch) or "dpmm" -
e.g. `--scalexdimdp=0.013in,300dpi`.
`--scmvv=INTEGER`
: For MaxiCode, prefix the Structured Carrier Message (SCM) with `"[)>\R01\Gvv"`, where `vv` is a 2-digit *INTEGER*.
`--secure=INTEGER`
: Set the error correction level (ECC) to *INTEGER*. The meaning is specific to the following matrix symbols (all
except PDF417 are approximate):
Aztec Code 1 to 4 (10%, 23%, 36%, 50%)
Grid Matrix 1 to 5 (10% to 50%)
Han Xin 1 to 4 (8%, 15%, 23%, 30%)

rMQR 2 or 4 (15% or 30%) (M or H)
Ultracode 1 to 6 (0%, 5%, 9%, 17%, 25%, 33%)
`--segN=ECI,DATA`
: Set the *ECI* & *DATA* content for segment N, where N is 1 to 9. `-d` | `--data` must still be given, and counts
as segment 0, its ECI given by `--eci`. Segments must be consecutive.
`--separator=INTEGER`
: Set the height of row separator bars for stacked symbologies, where *INTEGER* is in integral multiples of the
X-dimension. The default is zero.
`--small`
: Use small text for Human Readable Text (HRT).
`--square`
: For Data Matrix symbols, exclude rectangular sizes when considering automatic sizes.
`--structapp=I,C[,ID]`
: Set Structured Append info, where *I* is the 1-based index, *C* is the total number of symbols in the sequence,
and *ID*, which is optional, is the identifier that all symbols in the sequence share. Structured Append is
supported by Aztec Code, Code One, Data Matrix, DotCode, Grid Matrix, MaxiCode, MicroPDF417, PDF417, QR Code and
Ultracode.
`-t`, `--types`
: Display the table of barcode types (symbologies). The numbers or names can be used with `-b` | `--barcode`.
`--vers=INTEGER`
: Set the symbol version (size, check digits, other options) to *INTEGER*. The meaning is symbol-specific.
For most matrix symbols, it specifies size:
Aztec Code 1 to 36 (1 to 4 compact)
Code One 1 to 10
Data Matrix 1 to 48 (31 to 48 DMRE)
Grid Matrix 1 to 13
Han Xin 1 to 84
Micro QR 1 to 4 (M1, M2, M3, M4)
QR Code 1 to 40
rMQR 1 to 38 (33 to 38 automatic width)
For a number of linear symbols, it specifies check character options ("hide" or "hidden" means don't show in HRT,
"visible" means do display in HRT):
C25IATA 1 or 2 (add visible or hidden check digit)
C25IND ditto
C25INTER ditto
C25LOGIC ditto
C25STANDARD ditto

# EXAMPLES
Create "out.png" (or "out.gif" if zint built without PNG support) in the current directory, as a Code 128 symbol.
```bash
zint -d 'This Text'
```
Create "qr.svg" in the current directory, as a QR Code symbol.
```bash
zint -b QRCode -d 'This Text' -o 'qr.svg'
```
Use batch mode to read from an input file "ean_nos.txt" containing 13-digit GTINs, to create a series of EAN-13
barcodes, formatting the output filenames to "ean001.gif", "ean002.gif" etc. using the special character "~".
```bash
zint -b EANX --batch -i 'ean_nos.txt' -o 'ean~~~.gif'
```
