HISTORY NOTE:
You don't need these programs anymore when using at least QB64-PE v3.10.0 or later. As member of the QB64-PE developer team I've now finally added the functionality directly into the language. From version 3.10.0 on simply use the $EMBED metacommand to embed a file and the _EMBEDDED$ function to later recall the embedded file data. These new commands mainly implement the MakeCARR functionality described below, but in a much more convenient way.
See also: Keyword of the Day ($EMBED and _EMBEDDED$)
Embedding any files into your programs by converting it into DATA lines or an C-Array
The following two small programs are meant to convert any file (eg. Images, Sounds, Databases etc.) into an easy embedable format. Embedding is then as simple as putting a $INCLUDE line at the end of your program. The converted files will have "Ready to use" read and write functions, which either read the data into a string for use with the memory load capabilities of _LOADIMAGE, _LOADFONT and _SNDOPEN, or to write the embedded data back into a file on disk.
The first converter tool is named MakeDATA, as you may imagine by its name, it will convert the given file into a block of DATA lines. This is easy to use and absolutly BASIC code only. It's best to embed small files like icons or sprites. However, for large files like fullsize digital photos or MP3 music it has a big drawback at the compiling speed of your program and the final EXE size on one side and also to the read or write speed on the other side.
So for bigger files the second tool MakeCARR should be your choice, which its advantages are detailed below the MakeDATA codebox.
Note for Windows users:
The codeboxes below contain simple SCREEN 0 (text) based versions of the converter tools. You may have to go in to change your default paths, but they should work reliable on all OS's supported by QB64.
If you're on Windows, then you may rather wish to use the more convenient GuiTools based versions, just move on to
The GuiTools Framework here: https://qb64phoenix.com/forum/forumdisplay.php?fid=32
Both converter tools are available as part of the QB64GuiTools.7z source archive.
And now for the simple (SCREEN 0) people:
Both of the following tools require the 'lzwpacker.bm' file available from my Libraries Collection here:
https://qb64phoenix.com/forum/forumdisplay.php?fid=23
If you're using at least QB64 v1.4 or any Phoenix Edition version and don't wanna use the extra Lzw packer libarary, but the QB64 built-in zlib compression instead, then simply substitute the LzwPack$ call (line 86) with the respective _DEFLATE$ call and the LzwUnpack$ calls (lines 158+233) with an _INFLATE$ call. Also delete the $INCLUDE line at the end.

And now the second tool MakeCARR. It will do the whole thing in an array on C/C++ level, rather then in DATAs on the BASIC level. Although it's handling is a bit more tricky, as you get not only a .bm file, but also a .h file, and both must match (ie. the DECLARE LIBRARY path in the .bm must point to the .h), this approch has several advantages especially for big files:
- Unless DATAs, which are included in the final EXE as written (ie. as ASCII chars), a C-Array containing numbers is embedded as (you guess) array of binary numbers, hence even uncompressed it would not take more space than the original file. This makes the compression even more valuable, as it really reduces the final EXE size, instead of just compensating for the Number-to-Ascii bloat as for the DATAs.
- As the array is stored as successive numbers in memory, it's possible to write back the entire array with just one disk access, which is much faster than reading all single DATAs and concatenate them into one big string, which is then written out.
- As the converted data is not in the $INCLUDEd .bm file anymore (but in the .h file now), the syntax checking/compiling in the IDE will need less, depending on filesize much less time to finish, as it doesn't need to check 100s (or even 1000s) of DATA lines.
- On C/C++ level it's easy to expand the given write path/filename into a full qualified absolut path using a standard library call. This path/filename is returned through the write function and can be used in your program to always safely access the written file, doesn't matter how often you change the current working directory using the CHDIR statement.
- For any files, which are only needed temporarily during program runtime you can specify an auto-cleanup, which automatically deletes the written file again, as soon as your program terminates. This feature is also easily accessible on C/C++ level through an 'atexit()' function.
