Can you loadFromImage to RenderTexture?

[LordNani]

image.create(windowWidth, windowHeight, sf::Color::White);
sf::RenderTexture canvas;
sf::IntRect area = sf::IntRect(0, 0, image.getSize.x, image.getSize.y);
canvas.getTexture().loadFromImage(image,area);

I need it so I can open and edit images.

The texture of the RT cannot be accessed like this, it's read-only. Instead, load the image into a texture and draw it to your RT with a sprite.
