pictureToRaw takes a picture, decodes it, parses every pixel to a 4 digit RGB565 hex and saves it to a file with the same name and a .raw extention in the specified directory

This function takes two arguments

• first FilePath is the directory to save the file to
• second (Format, FilePath) is the format and filepath of the picture

Possible errors:

• Can throw an error if the picture format is not supported
• If there is an error while decoding the pictures the file gets skipped and an error message is printed out

Results:

If the conversion was successful, a message gets printed

cat_01_bmp_120x120.bmp --> cat_01_bmp_120x120.raw

Example usage: (assumed that the picture is in the directory where ghci was started)

λ> dir <- getCurrentDirectory
λ> pictureToRaw dir (Bmp, "cat_01_bmp_120x120.bmp")
cat_01_bmp_120x120.bmp --> cat_01_bmp_120x120.raw

pictureToC takes a picture, decodes it, parses every pixel to a 4 digit RGB565 hex, adds the header based on the desired platform and saves it to a file with the same name and a .c extention in the specified directory

This function takes three arguments

• Platform is the desired platform to convert to
• first FilePath is the directory to save the file to
• second (Format, FilePath) is the format and filepath of the picture

Possible errors:

• Can throw an error if the picture format is not supported
• If there is an error while decoding the pictures the file gets skipped and an error message is printed out

Results:

If the conversion was successful, a message gets printed

cat_01_bmp_120x120.bmp --> cat_01_bmp_120x120.c

Example usage: (assumed that the picture is in the directory where ghci was started)

λ> dir <- getCurrentDirectory
λ> pictureToC AVR dir (Bmp, "cat_01_bmp_120x120.bmp")
cat_01_bmp_120x120.bmp --> cat_01_bmp_120x120.c

Checking if the format is supported via magic bytes safe checking for everything unless .tga

Possible errors:

• It will be problematic in the future if you try to read the file as .tga if it's not encoded as one

Example usage:

 λ> toMaybeFormat "cat_01_bmp_120x120.bmp"
 Just Bmp
 λ> toMaybeFormat "cat_01_bmp_120x120.jpeg"
 Just Jpeg
 λ> toMaybeFormat "cat_01_bmp_120x120.jpe"
 Just Jpeg
