在 SFML 中，如何在没有缩放因子的情况下应用转换？

Question

I am creating a UI system in SFML based on the Object Hierarchy Example on the wiki. I have a TextBox node that contains an sf::Text object that I want to be displayed. My issue is that when I increase the scale factor of the sf::Text object, it zooms into the text making it appear pixely. It would make much more sense to just increase the font size, but I cannot figure out how to apply the transformations of the parent node minus the scale factor to prevent the zooming in effect. I have a very limited understanding of transformation matrices, which I gather are what applies the transformation. Any advice on how to proceed is appreciated.

I eventually found this question which helped me separate the scale factor from the transform matrix. For those with a similar problem, here is the solution I came to:

const float* mat = states.transform.getMatrix();
float temp[16];
std::copy(mat, mat + 16, temp); // mat has 16 members, hence mat + 16 is the last member
float scalex = sqrtf((temp[0] * temp[0]) + (temp[1] * temp[1]));
float scaley = sqrtf((temp[4] * temp[4]) + (temp[5] * temp[5]));
// Remove scale from the final transform
sf::Transform textState(
    temp[0] / scalex, temp[1] / scaley, temp[12], 
    temp[4] / scalex, temp[5] / scaley, temp[13],
    0.f, 0.f, 1.f
    );
