The present invention provides a method and system for transforming image data from a present format to a requested format. A request for the image data is received wherein the request includes a requested format, the requested format includes a first plurality of parameters. A present format for the image data is determined in response to receiving a request for the image data, wherein the present format includes a second plurality of parameters describing the image data. The first plurality of parameters within the requested format is compared to the second plurality of parameters within the present format describing the image data, wherein each parameter within the first plurality of parameters corresponds to a parameter within the second plurality of parameters. Parameters from the first and second plurality of parameters are identified, wherein a match between a parameter within the first plurality of parameters and a corresponding parameter within the second plurality of parameters is absent. The image data is altered utilizing the identified parameters, wherein the image data is transformed from a present format to a requested format.

Image format conversion such as photometric, rotation, cropping, padding, scaling, dithering, bit padding, grayscale and color transformation, encoding and decoding using a plurality of filters
