| - | * your function should take a rectangle modelled by a ''(Int, Int, Int, Int)'' tuple (the first two ''Int''s are the coordinates of the top-right corner, the next two ''Int''s are the height and width of the rectangle). It should return a new image with the same height and width as the rectangle selection containing the pixels in the image which fall withing the rectangle's area. | + | * your function should take a rectangle modelled by a ''(Int, Int, Int, Int)'' tuple (the first two ''Int''s are the coordinates of the top-left corner, the next two ''Int''s are the height and width of the rectangle).

| After having edited ''Main.hs'' you can run it; depending on the number of arguments, it will choose an appropriate type of transformation (single/multiple image); it also correctly chooses between greyscale/RGB functions based on the actual filetype. To run the file you need the ''runhaskell'' binary (or ''runghc''; both should come with the haskell platform), then run it from a shell: | After having edited ''Main.hs'' you can run it; depending on the number of arguments, it will choose an appropriate type of transformation (single/multiple image); it also correctly chooses between greyscale/RGB functions based on the actual filetype.

| - | For submission you should create a zip archive of the two files you modified: ''Greyscale.hs'' and ''Color.hs'' and a ''README''. The ''README'' should contain a succinct high-level presentation of your work. The archive name should be ''LASTNAME_Firstname_FP_A1.zip'' (if you have multiple firstnames, separate them by an underline "_"). Mail it to [[mailto:mihai.dumitru2201@upb.ro|mihai.dumitru2201@upb.ro]]. | + | For submission you should create a zip archive of the three files you modified: ''Common.hs'', ''Greyscale.hs'' and ''Color.hs'' and a ''README''.
