Hello!
I'm quite new to Magick++ and I have a big problem since some weeks.
I have a unsigned char array (pointer) with 76800 elements (320x240).
It's a gray scalled picture with one byte for each pixel.
I wrote a code where I reset every pixel, it was very slow but it worked fine.
Now I discouvered blob and wrote this code:
Magick::Blob image_blob(this->image,76800);
Magick::Image image(Magick::Geometry(width,height),"blue");
image.depth(8);
image.size("320x240");
image.type(Magick::GrayscaleType);
image.read(image_blob);
image.write("/tmp/magick_pp_test.jpg");
So I want wo convert this large blob in a jpeg file but the picture is always
blue (it's the backgroundcolor I set at the beginning).
So what do I make wrong?
One possible solution would be to set image.magick() but I was not able to find
out what i have to give him for a gray scalled picture.
Fabian
