Kudo½ Image Publisher(tm) for Windows TechNote

This file documents the structure and syntax of the KUDO.INI file.
The KUDO.INI file follows the standard Windows syntax for all .INI files.
******************************************************************************
These are the sections in KUDO.INI and their function:
[KudoImageBrowserImports] Associates a file extension with a filter DLL
[KudoPlacePacks] Associates an application with a place module
[OLEDropTargets] Identifies a registered OLE 2.0 drop target
Each of these sections can have zero or more entries following the section
header.
******************************************************************************
[KudoImageBrowserImports]
-------------------------
The entries in this section list all of the file types that Kudo Image Browser
can recognize and catalog. This feature is provided to enable users to add
more import filters & file types, and redefine what file extensions Kudo uses
to recognize each file type.
To read image and multimedia files of different formats, Kudo uses a modular
system based on the industry standard Aldus filter specification. This system
allocates a specific external Dynamic Link Library file (a .DLL file) for each
file type to be recognized. These DLL's are known as import filters, or
filters.
Kudo uses a file's extension to identify what type of file it is, and
consequently, which filter DLL to load in order to read that file. The
[KudoImageBrowserImports] section of KUDO.INI tells Kudo 1) what file
extension represents a particular file format, and 2) which filter to load in
order to read that file.
The syntax of one of these entries is:
<description>=<path>,<extension>
where
<description>: Cosmetic text that describes the particular file type
<path>: Path (full or relative) to the .FLT or .DLL file
that functions as the import filter for this file
type. This is a regular DOS pathname. If it is not a
fully qualified path, it is interpreted as relative to
the directory where the currently executing copy of
KUDO.EXE was found.
<extension>: 1-4 character text specifying the file extension to
associate with this file type. The dot '.' is
optional.
There should be no spaces around the equal sign ('=') or comma (','). For
example, the following entry:
[KudoImageBrowserImports]
ZSoft PC Paintbrush Bitmap=filters\IRPCX9.FLT,PCX
would be interpreted as follows:
<description>: "ZSoft PC Paintbrush Bitmap"
<path>: "filters\IRPCX9.FLT"
<extension>: "PCX"
This entry tells Kudo that 1) files with a .PCX extension are "ZSoft PC
Paintbrush Bitmap" files, and 2) the filter file "filters\IRPCX9.FLT" is the
filter DLL to load when trying to read these files.
For readability, the entries in the default KUDO.INI also include the file
extension at the beginning of the <description> field, but this is cosmetic -
only the <extension> field is actually used to determine the file extension.
The same filter DLL can be specified in more than one entry. This way it is
possible to alias several file extensions as the same file type. For example,
the Micrographix Drawing File Format is listed twice in the default KUDO.INI
file, for both the .DRW and .GRF file extensions. However, you can only
have one entry for each file extension. For example, you cannot have two
lines specifying .PCX as the file extension.
By convention, the filter DLL's that are shipped with kudo bear the file
extension .FLT, but they can have any file extension. It is recommended that
abide by this convention and use a .FLT or .DLL extension.
New file types can be added to Kudo simply by modifying KUDO.INI. Any DLL
that implements the Aldus Graphic Import Mechanism, either Interface Version
1.0 or 2.0, can be listed as an import filter in the [KudoImageBrowserImports]
section. This interface is documented in the Aldus "Filter Developer's
Toolkit", published by Aldus Corporation. For questions about the Aldus
standard, you can contact them at:

[KudoPlacePacks]
----------------
This section lists each of the available place modules. These Place Modules
are provided to enable Kudo to Drag and Drop with pinpoint accuracy onto
applications that fall into one or more of the following three categories:
1) applications that are not registered as OLE 2.0 drop targets in the
[OLEDropTargets] section (see below), 2) applications that do not accept an
image file drop from the File Manager, or 3) applications that require special
handling for a drop.
Kudo uses an application's window caption to identify it, and consequently,
match it with the appropriate place module, if it exists. The [KudoPlacePacks]
section of KUDO.INI tells Kudo 1) which applications have place modules, and 2)
which place modules to load in order to drag and drop to that application.
The syntax of one of these entries is:
<application name>=<path>,
where
<description>: The application caption as it appears on the title bar
<path>: Path (full or relative) to the .DLL file that functions
as place module for this application. This is a regular
DOS pathname. If it is not a fully qualified path, it
is interpreted as relative to the directory where the
currently executing copy of KUDO.EXE was found.
As in the [KudoImageBrowserImports] section described above, there should be
no spaces around the equal sign ('=') or comma (','). The ending comma is
required even if there is no accompanying comment.
******************************************************************************
[OLEDropTargets]
----------------
This section identifies applications which have implemented an OLE 2.0 drop
target interface and have been tested as drop targets with Kudo.
Kudo uses an application's window caption to identify it, and consequently,
match it with the appropriate data transfer object module. The [OLEDropTargets]
section of KUDO.INI tells Kudo 1) which applications are OLE 2.0 drop targets,
and 2) which data transfer object to load in order to drag and drop to that
application.
The syntax of one of these entries is:
<application name>=<path>,
where
<description>: The application caption as it appears on the title bar
<path>: Path (full or relative) to the .DLL file that functions
as the data transfer object module for this application.
This is a regular DOS pathname. If it is not a fully
qualified path, it is interpreted as relative to the
directory where the currently executing copy of KUDO.EXE
was found. By default, this data transfer object is
mdataxfr.dll.
As in the [KudoImageBrowserImports] section described above, there should be
no spaces around the equal sign ('=') or comma (','). The ending comma is
required even if there is no accompanying comment.
