Graphics / Re: sf::Image and sf::Text

I thought that. I've multiplied the width and height of the render target by 20% and it seems to do okay.

Thanks for your help!

Thanks very much to both, I hadn't thought of that!

However the text is being cut off at the bottom and right hand sides...

Graphics / sf::Image and sf::Text

« on: February 08, 2013, 09:40:04 pm »

Hi all.

I want to extract the rendered text from a sf::Text object into an sf::Image. Is that even possible? If so, please can someone let me know how?.

I'm new to SFML, but not to OpenGL and C++, so I hope I'm not doing anything wrong!

I've tried this:

sf::Font f;
f.loadFromFile("Resources/Fonts/Exo.otf");
sf::Text t;
t.setString("Hello There");
t.setFont(f);
t.setCharacterSize(24);
sf::Texture tx = f.getTexture(24);
sf::Image img = tx.copyToImage();
 

But that's no good to me, I've attached the GDEbugger run of the code to get a peek at what is in the texture and it's not what I want at all.

I need to use the sf::Image for getting the texture into OpenGL as I'm managing my own textures i.e.

glTexImage2D(GL_TEXTURE_2D,0,GL_RGBA,img.getSize().x,img.getSize().y,0,GL_RGBA,GL_UNSIGNED_BYTE,img.getPixelsPtr());

Any ideas would be helpful,
Thanks.
