Hi,
I am trying to set an image on disk to my texture. Image dimension is 1800 by
1200 i.e. width = 1800 & height = 1200. But I am doing something wrong here due
to which I am getting bad output. Can anyone help me here. This is my code -
std::ifstream imageToRead;
imageToRead.open("E:\\my
code\\OpenSceneGraph-3.3.7\\OpenSceneGraph-Data-3.0.0\\Images\\1.jpg",
std::ios::in | std::ios_base::binary);
imageToRead.seekg(0, std::ios::end);
int n = imageToRead.tellg();
imageToRead.seekg(0, std::ios::beg);
char* res = new char[n];
imageToRead.read(res, n);
imageToRead.clear();
imageToRead.close();
osg::Image* bufferImage = new osg::Image;
bufferImage->setImage(1800, 1200, 1, GL_RGB, GL_RGB, GL_UNSIGNED_BYTE,
(unsigned char*)res, Image::USE_NEW_DELETE);
osg::Texture2D* texture = new osg::Texture2D(bufferImage);
texture->setResizeNonPowerOfTwoHint(false);
stateset->setTextureAttributeAndModes(0, texture);
...
Thank you!
Cheers,
Harshal
