The _EMBEDDED$ function is used to recall the data of a file which was earlier embedded into the EXE file using the $EMBED metacommand. You can roughly compare this to a RESTORE to any DATA block and then using READ to retrieve the data.
Syntax
- filedata$ = _EMBEDDED$("handle")
Parameters
- IMPORTANT
-
- The parameter handle must be given as a single literal string enclosed in quotes, variables cannot be used here.
- The parameter will be checked while typing to ensure its validity, warnings (if any) will be displayed immediately in the IDE status area.
- The filedata$ will receive the embedded file data as a single contiguous string, just as you would regularly OPEN the file and read its entire contents into that string.
- The handle is a unique case sensitive identifier beginning with a letter and only containing lower/upper case letters and/or numbers. It must exactly match the handle value used to $EMBED the respective file.
Description
- All embedded files can be recalled individually by using its respective handle identifier. ** If required, decompression is done internally, hence you always get back the original file contents.
- Recalling a file multiple times is possible, but in regard for the needed decompression time considered inefficient. Rather recall the file once and store the result in a STRING variable, if you know you need it multiple times in your program.
- To easily embed a file into your compiled EXE file use the $EMBED metacommand.
- Embedding files can be useful to deliver a program inclusive all required assets in just one EXE file.
- No more worries whether a user installs your program correctly and retains the required folder structure.
- If required, you can write the files back to disk, i.e. it could serve as an simple installer or package manager.
- Embedded images, sounds or fonts can be passed directly to _LOADIMAGE, _SNDOPEN or _LOADFONT respectively when using the memory load capabilities of these functions.
Availability
Examples
- Example
- Embeds two image files into the compiled EXE, then memory loads and displays it.
$EMBED:'source\peLogo.png','bigImg' $EMBED:'source\qb64pe.png','smallImg' SCREEN _NEWIMAGE(640, 480, 32) bi& = _LOADIMAGE(_EMBEDDED$("bigImg"), 32, "memory") si& = _LOADIMAGE(_EMBEDDED$("smallImg"), 32, "memory") _PUTIMAGE (140, 180), bi& _PUTIMAGE (410, 230), si& _FREEIMAGE si& _FREEIMAGE bi& END |
