Forgive what is likely a newbie question.
I'm trying to write out an unsigned 16-bit tif image using
osgDB::writeImageFile. Here is a very simple program to write out a 100
x 100 image ...
==============================================================
#include <osg/Image>
#include <osgDB/WriteFile>
#include <string>
int main()
{
int n = 100;
osg::Image* resultImage = new osg::Image;
resultImage->
allocateImage(n, n, 1, GL_LUMINANCE, GL_UNSIGNED_SHORT);
unsigned short* ptr = (unsigned short*) resultImage->data();
for (int i=0; i<n; i++)
{
for (int j=0; j<n; j++)
{
*(ptr++) = 1500 + j;
}
}
osgDB::writeImageFile(*resultImage, "foo.tif");
}
==============================================================
The resulting image is treated as an 8-bit image with each pixel as a
byte in the unsigned short. From stepping through the readerwriter.cpp
code, it looks like this is the intended behavior.
Two questions:
1) Does this code account for images other than 8-bit?
2) Is there another way I should be calling this?
Thanks for any help, matt
