ImagePro>Re: Can a IPBasic macro call a Macro made with the SDK?

["Kevin Ryan" <kevin[at]mediacy.com>]

Normally we don't recommend calling macros from C/C++ code. There's no
guarantee that the appropriate macro is available! However, it's quite easy
to call C/C++ code from a macro. If you have the SDK, the .BAS files define
functions and their arguments, along with the DLL they are in, and expose
their functionality to macros. Look at Bas\ipc32.bas for examples.

In terms of converting macros to C/C++ code, the ShearStk example in the SDK
is there for that very reason. The shearstack code was first written as a
macro, then converted to C for compilation. Note that the calls to IPP
operations copy over very directly, with the only real changes being
variable types (Single->float, Integer->short), the use of pointers for
return values (&val instead of val where it's passed by "As Any"), and
semicolons after each line. BASIC commands and structural items such as
Select, If-Then-Else, etc. must be converted to the matching C commands such
as "switch", "if () {} else {}", and so on.

Creating functions with the SDK wizard will generate a few macro calls,
which can be converted to .BAS files using the .BAT file in the wizard
generated directory, and if copied to the \Bas directory expose the C/C++
functions to IpBasic. Additional macro functions can be added by editing the
template-generated code in a few sections.

If you need to call something that doesn't have an IPBasic interface (rare,
but there are a _few_ examples), look at IpAppMenuSelect( ), IpAppCtl( ),
and the other IpApp... commands. In general, there's a direct IpBasic call
for just about anything, and the IpApp commands are there as a last resort.
