how to properly to use this shader?

[Rhimlock]

Just a guess:

What height does texture have after you set it to your render texture at the end?

texture = render_texture.getTexture();

How do you draw those textures? Maybe your sprite's height is limited to the original fonts height.

well, it's exactly the same from render_texture.
by using

std::cout << "\ntexture size:" << texture.getSize().x << "," << texture.getSize().y;

after the last line, i get

text size:344,65
render_texture size:364,85
texture size:364,85

i think that something is wrong when creating the RenderTexture size.

Try changing

render_texture.create(text.getGlobalBounds().width + outline_thickness*2, text.getGlobalBounds().height + outline_thickness*2);

To

render_texture.create(text.getGlobalBounds().width + outline_thickness*4, text.getGlobalBounds().height + outline_thickness*4);

[Stauricus]

yeah, i tried it. for some reason, i get the best results with

    render_texture.create(text.getGlobalBounds().width + outline_thickness*2, text.getGlobalBounds().height + outline_thickness*4);

and

    text.setPosition(outline_thickness, 0);

what does not make any sense to me. the horizontal bounds are perfect. but the vertical is nonsense. maybe it's something related to the font usage...

Use bounds.left + bounds.width (same on Y). Don't assume that left and top are always zero, they are not for sf::Text.

[Stauricus]

do you mean something like this?

float texture_width = text.getGlobalBounds().left + text.getGlobalBounds().width + outline_thickness*2;
float texture_height = text.getGlobalBounds().top + text.getGlobalBounds().height + outline_thickness*2;
render_texture.create(texture_width, texture_height);

much better. but it still cuts a bit of the text (look below the "G" and "T")


BUT all the fonts works if i use the line

text.setPosition(outline_thickness, 0);

instead of

text.setPosition(outline_thickness, outline_thickness);

although if we don't have an explanation, it's good enough for me, as it's working
