2055<p>MagickGetImageBlob() implements direct to memory image formats. It returns the image sequence as a blob and its length. The format of the image determines the format of the returned blob (GIF, JPEG, PNG, etc.). To return a different image format, use MagickSetImageFormat().</p>
2056
2057<p>Note, some image formats do not permit multiple images to the same image stream (e.g. JPEG). in this instance, just the first image of the sequence is returned as a blob.</p>

6302<h5>fuzz</h5>
6303<p>By default target must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. The fuzz member of image defines how much tolerance is acceptable to consider two colors as the same. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color for the purposes of the floodfill.</p>
