How to connect blob filter to ibexpert?
I need to add one more bookmark of mine to the bookmarks "As Text - ANSI", "As Hex", and so on.
Wrote the simplest filtr with a function call from a dll, but ibexpert does not see it anywhere. :(

DECLARE FILTER show_BLOB
       INPUT_TYPE  BINARY output_type TEXT
       ENTRY_POINT 'show_BLOB' MODULE_NAME 'BLOB_Filter'

function show_BLOB(action: Word; control: PISCBlobCtl): Integer; cdecl;
...
exports show_BLOB;
