Hello,

I copy a texture image in a image2d but the result is a black picture.
When i draw the rtt Image on the Display is all right.

PHP Code:

if(!rtt.is())
{rtt.create(tex_size, tex_size,1 , IMAGE_B8G8R8A8, IMAGE_RT, 1);
 rtt.copyTry(im,1,1,1,IMAGE_2D,1,FILTER_NONE);} 

Greetings Denis

Use Header Browser to read the comments for Image::copyTry. Count the number of arguments you are passing carefully, as well.

Hello

Is it possible that the DrawMask not work with the image rt?

Hello,

The Copy methode not work, i think i wrote my own copy. don't work why?

PHP Code:

....
inImage.create(tex_size, tex_size,1 , IMAGE_B8G8R8A8, IMAGE_RT, 1)
outImage.create(512, 512,1 , IMAGE_B8G8R8A8, IMAGE_2D, 1);
....


Image &pointCopy(Image &inImage,Image &outImage)
{
      //Image über Matrix drehen
      signed x1 = inImage.x()/2;
      signed y1 = inImage.y()/2;
      if(inImage.lock() ) 
      {
        if(outImage.lock() ) 
       {  
          FREPD(y, inImage.y()) 
            FREPD(x, inImage.x())
            {
                outImage.pixel(x, y, inImage.pixel(x,y));
            }
        inImage.unlock(); 
    }
      outImage.unlock(); 
    }


    return outImage;
}

the only way to access IMAGE_RT data is to use Renderer.capture or Renderer.screenshot, very slow (not for realtime use)

IMAGE_RT can be used as 2d texture for drawing, so if you want to use it for drawing, you don't need to copy it anywhere.
IMAGE_RT alpha channel may be undefined - important
