--- Comment #8 from Adrian Johnson <ajohnson at redneon.com> ---
I don't like to keep adding parameters to a function where only a subset of the
parameters are used for each call. We already have the tiff compression
parameter and more parameters may be added in future.

Alternatively how about we use a struct for all optional parameters. eg

struct WriteImgParams
{
  int jpegQuality = -1;
  GBool jpegProgressive = gFalse;
  GooString tiffCompression;
};

SplashError writeImgFile(SplashImageFileFormat format, char *fileName, int
hDPI, int vDPI, const WriteImgParams& params);
