The TBJPG.DLL is a file-converter. It converts a JPEG to a BMP in a single
call. As a ToolBook-developer you can add this DLL to your files and re-distribute it with applications you create.
The
primary function is TransferJPEG. After linking the DLL, the
call
TransferJPEG(jpgFile, bmpFile)
takes an existing JPG-file (the first parameter, a regular TB-string) and creates
the equivalent Windows BMP (bitmap), which is specified in the second parameter. This, too, is a regular TB-string.
