How to change texture of image to other texture. Example a wall texture change with texure

I’m a little confused–did we not address this earlier in the thread? Or do you mean something different now than you did then?

I resolved all the problem as per your guidelines. But now i have to change texture in image. Previously We are changing texture of model but now i have to change texture of image.

We previously discussed that, too, I think:

@078_Rohit_Ojha

No i want to change the texture of wall in the apartment image.

@Thaumaturge

… the PNMImage class and its associated classes provide one fairly simple way of replacing part of an image.

My requirement is when i click on wall it will change all wall texture with my saved texture.

@Thaumaturge

Ah. In that case, I suggest doing some research on the broader internet–there will be resources describing methods of doing this, I think.

(If your wall is just a flat colour–no shading or texture–then you could perhaps use a flood-fill technique to detect the pixels that belong to the wall, and thus which pixels to replace.)
