Network / Help with downloading a text file off a website [Solved]

« on: July 16, 2011, 06:48:29 pm »

Hello.

I am trying to use either the HTTP or FTP examples (but I don't really understand them), but a valid webpage is returning 1001 (Connection Failed).

The page I want to access is here:
http://www.swpc.noaa.gov/ftpdir/lists/ace//20110715_ace_mag_1m.txt

But it's being reported as a 1001. I know if I can access it successfully, all I would merely have to do is merely copy from .Body into a file, which is simple enough.

What modifications do I need to make (note, I tried modifying the website address but only got 1001) to the HTTP (or FTP?) example to get it to successfully obtain the text file?

Thank you.

Graphics / Sprite scaling/resize relativity issue

« on: May 23, 2011, 12:18:10 am »

Hello,

I've got a window of a specific size (512 x 512), and any images whose height is lower than this (256) or greater than this (1024, 2048), have their sprite rescaled to match the 512 requirement.

The problem is, I find the scale/resize system relative rather than absolute, so, for example:

If I load an image that is 256 to sprite, and resize/scale sprite to fit 512, and then I reload another image (also 256), and then resize/rescale sprite - instead of sprite still being 512, sprite becomes 1024, 2048 etc etc.

How do I make it so the scaling of sprite is reset to normal?

Thank you.

Graphics / If Image.Create can only work in powers of two, why...

« on: April 26, 2011, 02:09:46 pm »

...Can I set a render window size to 755 by 3, and load an image that is 173 by 371?

I don't understand why creating has to conform to the powers of two, but already created images that are loaded and render windows, don't?

Either the graphics card can render non-powers of two, or it can't. But it cannot logically be both or neither.

I really need to be able to create images that are a non-power of two to be able to properly render a graph.

So my help question is thus:

What part of the SFML code do I alter and recompile to disable the power of two lock that appears to be completely unnecessary?

Or, alternately;

How do I create a non-power of two image.
