Stretch Sprite/Texture
« on: January 14, 2013, 07:49:45 am »
Hey, I can't find the answer to this anywhere (Well I could but not for 2.0)

How do I simply stretch a, say, 100x100 image to 1024x768.

sf::Texture/Sprites have no setSize() functions so I'm not sure, does it have something to do with views?

Thanks.  ;)

sf::Sprite::setScale()

You have to calculate a little bit. The sprite's size can be retrieved from the rectangle sf::Sprite::getLocalBounds().

Hmm what sort of calculation? I've tried setScale  but it seems to stretch the image way beyond the size I'm specifying. But I also can't seem to find any documentation of setScale for 2.0 either, so I'm not sure what it's doing.

Any ideas?  :P

Thanks  ;D

http://www.sfml-dev.org/documentation/2.0/classsf_1_1Sprite.php#a4c48a87f1626047e448f9c1a68ff167e

There's where it is in the documentation.

If it helps (because the documentation never fully explains), you can get a number to give Sprite::setScale() if you ask yourself this question:

What do I need to multiply 100x100 by to get 1024x768? Which really means: What's 1024/100, and 768/100? The result will be 10.24 and 7.68, which are the values you can give setScale in this case.
