Generating the entire glyphs texture

[tanis]

Is there a simple way to tell SFML to generate the entire glyph texture at a certain size when loading the font?
I know the implications, but for the kind of use I have in mind I'm pretty sure the texture would be small enough to fit in memory and it would let me feed the text to a sprite batcher without having to flush it every time a call to render the text is issued.
Thanks in advance!

const char charset[] = "abcdefg...";
for (auto c : charset)
    font.getGlyph(c, size, false);

Untested, but should be enough.

As dirty as it is but it definitely works well. Thanks!

Querying glyphs so that they are cached before being used is not "dirty". We could as well create a Font::preload(charset, size) function and it would look cleaner although exactly identical. What's dirty is assuming that all your glyphs fit in a single texture, which heavily depends on your GPU capabilities and on SFML internal code

All glyphs of the same character size are guaranteed by SFML to fit in a single texture.

I guess it depends on the size of the font. If it's too big, then it won't fit in a single texture. I don't know what happens internally in SFML at that point though.

It's true that SFML doesn't handle this case, but it doesn't guarantee anything: if they don't fit, new glyphs are discarded and a warning is printed on sf::err().
