% Convert converts an input file using one image format to an output file
% with a differing image format.
%
% The convert program syntax is:
%
% Usage: convert [options ...] input_file output_file
%
% Where options include:
% -adjoin join images into a single multi-image file
% -average average a set of images
% -blur factor apply a filter to blur the image
% -border geometry surround image with a border of color
% -box color color for annotation bounding box
% -charcoal factor simulate a charcoal drawing
% -colorize value colorize the image with the pen color
% -colors value preferred number of colors in the image
% -colorspace type GRAY, OHTA, RGB, XYZ, YCbCr, YIQ, YPbPr, or YUV
% -comment string annotate image with comment
% -compress type RunlengthEncoded or Zip
% -contrast enhance or reduce the image contrast
% -crop geometry preferred size and location of the cropped image
% -cycle amount cycle the image colormap
% -delay value display the next image after pausing
% -density geometry vertical and horizontal density of the image
% -despeckle reduce the speckles within an image"
% -display server obtain image or font from this X server
% -dispose method GIF disposal method
% -dither apply Floyd/Steinberg error diffusion to image
% -draw string annotate the image with a graphic primitive
% -edge factor apply a filter to detect edges in the image
% -emboss emboss an image
% -enhance apply a digital filter to enhance a noisy image
% -equalize perform histogram equalization to an image
% -flip flip image in the vertical direction
% -flop flop image in the horizontal direction
% -font name X11 font for displaying text
% -frame geometry surround image with an ornamental border
% -gamma value level of gamma correction
% -geometry geometry perferred size or location of the image
% -implode amount implode image pixels about the center
% -interlace type None, Line, Plane, or Partition
% -label name assign a label to an image
% -linewidth value width of line in pixels
% -loop iterations add Netscape loop extension to your GIF animation
% -map filename transform image colors to match this set of colors
% -matte store matte channel if the image has one
% -modulate value vary the brightness, saturation and hue
% -monochrome transform image to black and white
% -negate apply color inversion to image
% -noise add or reduce noise in an image
% -normalize transform image to span the full range of colors
% -opaque color change this color to the pen color
% -page geometry size and location of the Postscript page
% -paint radius simulate an oil painting
% -pen color color for annotating or changing opaque color
% -pointsize value pointsize of Postscript font
% -quality value JPEG quality setting
% -raise value lighten/darken image edges to create a 3-D effect
% -region geometry apply options to a portion of the image
% -roll geometry roll an image vertically or horizontally
% -rotate degrees apply Paeth rotation to the image
% -sample geometry scale image with pixel sampling
% -scene value image scene number
% -segment values segment an image
% -shade degrees shade the image using a distant light source
% -sharpen factor apply a filter to sharpen the image
% -shear geometry slide one edge of the image along the X or Y axis
% -size geometry width and height of image
% -solarize thresold negate all pixels above the threshold level
% -spread amount displace image pixels by a random amount
% -swirl degrees swirl image pixels about the center
% -texture filename name of texture to tile onto the image background
% -threshold value threshold the image
% -transparent color make this color transparent within the image
% -treedepth value depth of the color classification tree
% -undercolor geometry control undercolor removal and black generation
% -verbose print detailed information about the image
% -wave geometry alter an image along a sine wave
%
% Change '-' to '+' in any option above to reverse its effect. For
% example, specify +matte to store the image without its matte channel.
%
% By default, the image format of `file' is determined by its magic
% number. To specify a particular image format, precede the filename
% with an image format name and a colon (i.e. ps:image) or specify the
% image type as the filename suffix (i.e. image.ps). Specify 'file' as
% '-' for standard input or output.
%
% Convert recognizes the following image formats:
