magickcore api questions

Hi there,
I have two questions concerning the magickcore api:
1) I'm using the Q8 version of ImageMagick (ImageMagick-6.5.8 ). What kind of dithering is taken place when opening a 3x16bit tiff image with ReadImage?
2) Regarding animated images. Suppose I open an animated tiff image (with images having a slightly different width/height) with ReadImage and CoalesceImages. How are the images in the animation aligned and how is decided what the size of the canvas is? (I know that the images in a gif animation have offsets, but i don't think that's the case for a tiff animation?)
edit:
I'm a bit confused now. This is what identify says about the tiff file:
I expected that the canvas is the same for every image. How is CoalesceImages deciding how to coascale them? Does it take the width/height of the first image and crop the subsequent images?
