Inline Data does not know what kind of data you store, so you have to choose the right type, and FLUID does not know how you will use the data later. You are using it for and svg, but FLUID does not know that. If your svg is uncompressed XML, you should choose text. If it is a compressed svgz, you should choose binary. If you select "compress", the FLUID will compress the data for you using zlib, but that is completely unrelated to the type of data. You have to uncompress it before you can use it:

OK, so for the Inline Data node I have to uncompress the node myself... OK.
I had though that the :

Fl_SVG_Image::Fl_SVG_Image(const char * name, const unsigned char *
svg_data, size_t length)

method would do that for me, so that is what I used in my fluid file.

The docs say: "This constructor loads the SVG image from a block of
memory. This version is commonly used for compressed binary data, but
the reader recognizes if the data is uncompressed, and reads it as a
text block." so I was hopeful this would Just Work, but in testing it
does not. I'll try unpacking the data manually...

Though probably the raw text is fine for me anyway, TBH...
