AW: [magick-developers] SVG: rotate image with a multiple of 90

[Thomas.Stegemann at materna.de]

In the file "magick/draw.c"
in the function "MagickBooleanType DrawPrimitive(Image *image, const DrawInfo *draw_info,const PrimitiveInfo *primitive_info)"
for the case "ImagePrimitive"
removing the test (ExpandAffine(&affine) != 1.0), solves the problem:

      if ( /* (ExpandAffine(&affine) != 1.0) && */
          (draw_info->compose == OverCompositeOp))
        (void) DrawAffineImage(image,composite_image,&affine);
      else
        (void) CompositeImage(image,draw_info->compose,composite_image,
          geometry.x,geometry.y);

Cheers,
Thomas Stegemann
