What do you mean by "but I thing you need to use
GL_RGBA_INTEGER_EXT as source"<br>

The source type needs to be GL_RGBA_INTEGER_EXT afaik when using
integer textures. <br>

Which macros? The GL_ are constants. <br>

<div>Hi,<br>
<br>
Your internal format needs to be 16bit per channel to I
think, so GL_UNSIGNED_INT_8_8_8_8_REV might be
inappropriate. <br>
GL_R16UI might do, but I thing you need to use
GL_RGBA_INTEGER_EXT as source. Alternatively you can use
GL_LUMINANCE with GL_LUMINACE16F.<br>
<br>
What exactly are you doing with the image? <br>
<br>
Cheers<br>

<div>Hello,<br>
<br>
</div>
I have a 16bit per channel, 4 channel,
image. The format is short (uint16_t).
Note that this image is scaled to the
full 16bit depth [0, 65536]<br>
<br>
<br>
</div>
I have this code that works well for a
8bit, 4 channel image:<br>
<br>
osg::ref_ptr<osg::Image> image =
new osg::Image(); <br>
image->setImage(ImageSize,
ImageSize,1,<br>
GL_RGBA8,<br>
GL_RGBA,<br>
GL_UNSIGNED_INT_8_8_8_8_REV, <br>
</div>
MyDataPtr,<br>
osg::Image::NO_DELETE);<br>
<br>
<br>
<br>
</div>
Now I want to por this to 16bit depth.<br>
</div>
How is this done?<br>
<br>
</div>
I tried<br>
<br>
image->setImage(ImageSize, ImageSize,1,<br>
GL_RGBA16UI,<br>
GL_RGBA,<br>
GL_UNSIGNED_INT_8_8_8_8_REV, <br>
MyDataPtr,<br>
osg::Image::NO_DELETE);<br>
<br>
</div>
But this yields all black textures. How can I do
this without converting my 16bit image pixel data?<br>
