parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."
It should not be introusive to any other palatform apart MSVC, but in order to link to debug-specific libs
I had to change plugins CMakeLists to differentiate debug/release linkage, I have used the same macro used in core libs
Now the macro used for plugin and examples linking test for existance of TARGET_LIBRARIES_VARS
that holds the names of the variables that have to be used for linking"
not find a way to do this in OSG. Therefore I implemented this by adding
an option called: JPEG_QUALITY <quality> to the JPEG reader/writer.
To parse the options string I use the same method as used in the LWO
reader/writer. "
instead of osgDB::Registry where it original lay. This has been done to allow
fileName strings to be encode data rather than just file names, such as one
requires when using PagedLOD along with plugins for doing dynamic tesselation.
2) Changed Makedepend system to make individual dependency files, which
should save time rebuilding dependencies by limiting the regeneration
of dependency file for only modified source files.
osg::Image::setImage has also been modified to require the AllocationMode
mode to be passed to it so that it knows how to delete the data once the
image goes out of scope.
Port the image plugins across to specify the new AllocationMode, and converted
them across to using new/delete in place of malloc/free.
library and plugin files that looked like system library and system files
which would have deleted original files on a 'make install'. Cygwin is not
tested yet, but this needed to get fixed before a cygwin user wiped out his
system library files.
Added distrules and makerpms for building RPM distributions
Removed old RedHatRPM distribution build directory
Added new dist/RPM directory and placed temporary .spec files (these
are generated by Make/makerpms and are not intended for stand-alone
use, but they keep the directory warm and CVS happy)
added prefixes and suffixes to libs and plugins. ALl this to accomodate
cygwin...
Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
