Filter registration and some simple filters (also descriptions).
|
|
|
|
Desperate splitting of code into small shared libraries for historical
|
|
reasons presumably (OS/2 and Windows 3.x). The libraries produced from
|
|
the code in each subdirectory of filter/source/graphicfilter are
|
|
graphic format import or export filters. But they don't have uniform
|
|
API. Some have either an GraphicImport or GraphicExport entry point,
|
|
and are loaded and used in a uniform fashion from code in
|
|
svtools/source/filter/filter.cxx. Others have different API and are
|
|
loaded from other places. For instance "icgm" has ImportCGM, and is
|
|
loaded and used by sd/source/filter/cgm/sdcgmfilter.cxx (!).
|
|
Svgreader is used for "File->Open" and then to choose the svg file.
|
|
For "Insert->Picture->From File", see svgio/source/svgreader directory.

filter configuration
|
|
====================
|
|
|
|
The filter configuration consists of two parts, the type definition in
|
|
filter/source/config/fragments/types/ and the actual filter definition
|
|
in filter/source/config/fragments/filters/.
|
|
|
|
Each file type e.g. text file should be represented by exactly one
|
|
type definition. This type can then be referenced by several different
|
|
filters, e.g. calc text, writer text.
