The blending service shall meet the following criteria:
	- Allow the user to specify a base image layer of all supported formats (png, jpg, gif)
	- Allow the user to specify an overlying  image layer of all supported formats (png, jpg, gif)
	- Allow the user to specify how much of the overlying image shall blend in with the base (on scale of 0 [top layer invisible] to 100 [top layer opaque])
	- Preserve the alpha transparency of both the bottom layer and top layer accordingly (scaling the transparency of top layer according to scale above)

** TEXT SERVICE **
The text service shall meet the following criteria:
	- Allow the user to sepcify a base image layer of all supported formats (png, jpg, gif)
	- Allow the user to specify overlying text over the base layer
		-- Allow the user to specify font of the text
		-- Allow the user to specify size of the text
		-- Allow the user to specify color of the text
		*-- Allternatively (to option above) Allow the user to specify another image to use as fill for text (textured, instead of colored text)
		-- Allow the user to specify the alpha blending of the text
		-- Allow the user to specify the horazontal alignment of text (left, center, right)
		-- Allow the user to specify the vertical alignment of text (top, middle, bottom)
		*-- Alternatively (to both options above) allow user to specify absolute position of the text
		-- Allow the user to specify orientation of text (using rotation angles)

** FILTER SERVICE **
The filter service shall meet the following criteria:
	- Allow the user to apply one [or more] of the filters listed below to a base image layer of all supported formats (png, jpg, gif)
		-- Negate
		-- Grayscale
		-- Colorize (using specified R, G, B triplet for color)
		-- Brightness (adjusting the brightness accordingly)
		-- Contrast (adjusting the contrast accordingly)
		-- Edgedetect
		-- Emboss
		-- Gaussian Blur
		-- Selective Blur 
		-- Mean Removal ('sketchy look')
		-- Pixelate (according to value)
		-- Smooth (according to value)

** MASKING SERVICE **

	- Allow the user to apply a grayscale bitmap (or png) mask to an image
	- Allow the user to specify a specific color to mask out

*** OPTIONAL SERVICES ***

All services below are optional and may not be implemented.  However, upon implementation, they shall attempt to meet their specified criteria.

** COMBINATION SERVICE **
The combination service shall meet the following criteria:
	- Allow the user to combine two or more of the above services to create more complex composite images
		-- (i.e. blending service combined with text service to allow an overlay to be placed over the image with text on it)

** SAVING SERVICE **
The saving service shall meet the following criteria:
	- Allow the user to save a copy of images output from any of the above services, and give a unique identifier for short-hand linking.
		-- This will save the image on the server itself, the image is recalled from the server using the unique identifier assigned during the saving process


** USER INTERFACE **
A simple to use UI shall be provided via an HTML webpage to allow users to easily use these services.  It shall meet the following requirements:
	-- Allow the user to easily work with each of the above listed services (giving them input forms for each of the required and optional parameters)
	-- Allow the user to preview what the rendered result would look like
	-- Give the user an easy-to-use link to the image
