NAME
reswrap - wrap icon resources into C code
SYNOPSIS
reswrap [options] [-o[a] outfile] files...
DESCRIPTION
Reswrap is a tool to turn images, text, and other resource files into
C++ data arrays. This allows various binary resources to be embedded
in the source code, and compiled into an application.
In development of graphical applications with FOX, it is used to embed
icons and images for the user interface into the executable and
eliminate the need to distribute separate icon and image files.
Reswrap is typically invoked as a part of the build process to
generate C++ source files from a collection of icons and images and
other binary resources.
By default reswrap will interpret the files listed as a stream of raw
bytes and output them as an initialized data array to stdout.
OPTIONS
-o[a] outfile
Write the result into the file outfile instead of writing to
stdout. With -o the outfile will be overwritten with the data
from the input. With the -oa option, the resulting code is
appended to the output file, allowing multiple input files to be
placed into one single source file.
-h Print a short usage message.
-v Just print out the version number and license information.
-d Write data as decimal numbers instead of using the default
hexadecimal numbers.
-m Read files with MS-DOS mode (default is binary). This replaces
"\r\n" with "\n" when reading the resource file.
-x Write data as hexadecimal numbers (default).
-t[a]

Write data as a text string, with each byte represented as a
hexadecimal excape sequence, as in "\x33".
Note that the C++ compiler appends a nul-character at the end of
the text string, thus making the data array one character longer
than the file.
With the a option, printable ascii characters are passed
unescaped, while special characters like tabs and newlines are
given the usual escape codes.
-e Places the storage modifier extern in front of the data array,
ensuring that the data array can be linked with other compilation
units. Normally, constant declarations are not visible in other
compilation units.
-i Instead of generating an array definition only write a
declaration, which can be included as a header file.
-k This option causes reswrap to keep the file extension, replacing
the "." with an underscore "_". Usage of this option is
recommended as it reduces errors when using the data arrays.
-s This option suppresses comments inserted by reswrap to indicate
the original file name from which the data statement was
generated.
-p prefix
Prepend the given prefix in front of the name of the resource;
this may be used to generate class names or namespace names in
front of symbols.
-n namespace
Generate all declarations inside the given C++ namespace
declaration. Using a namespace may be used to ensure that
declarations are only accessible within the given scope, and thus
won't clash with symbols.
-c cols
Writes cols columns instead of the default number of columns in
the data statements generated by reswrap. The default number of
columns for decimal and hex printout is 16 characters; the

default for text string printout is 80 characters.
-u Force output as unsigned chars in text mode.
-z Output the size of the resource in the declaration of a
resource-array. This allows the C++ sizeof() operator to return
the correct size of the resource even for external declarations.
Note that in text mode, (-t option), an extra byte is added to
the size for the end of string character.
-r name
Instead of using a resource name based on the filename, reswrap
substitutes name for the resource name used in the declaration or
definition for the following resource file. This is useful if
the filename can not be used as an identifier, for example if the
filename is a reserved word in C or C++, like "while".
CAVEATS
When using the text string mode, please remember the C compiler
appends one nul-character after the string, making the data array one
element longer than the resource file.
