When i zoom in the output image i. Segmentation Use -segment to segment an image by analyzing the histograms of the color components and identifying units that are homogeneous with the fuzzy c-means technique. Anyway, this method is mainly for vectorial elements that can be rasterized at a higher density and then get downsized and the downsizing does some sort of antialiasing. The extents of each class is used to coarsely segment the image with thresholding. This works good for teh most files. The color associated with each class is determined by the mean color of all pixels within the extents of a particular class.

I don't actually recommend it as a general solution, because of this. The latter can appear after the final group of input images.

It seems to me that +antialias only turns off between colors aliasing but doesn't prevent to-alpha-channel aliasing. If it's something like Adobe Reader, then you might have to set the viewing resolution in the preferences to 72 ppi. Note that the best value to use varies depending on if the circle is centered either on an actual pixel such as ' 5 , 5 ' , or on a half pixel boundry such as ' 5. How can I make it? But even if you can't change that, you shouldn't worry. It will be scaled so its largest dimension is 120 pixels.
