The two parameters are as follows: filename is the first and the compulsory parameter to be passed and it takes a string value representing the path of the image . I'm just not sure how to go about converting the floating number range in the hdr to a jpg image bit-depth. Using the draft() method, you can speed things up by invisible RGB values for better compression. encoded using RLCP mode will have increasing resolutions decoded as they convert myexr.exr -colorspace RGB -colorspace sRGB mynonlineartiff.tiff If you are using any transfer function other than the sRGB EOTF, the process would require further effort, and in most cases, ImageMagick would be an unacceptable tool to harness.
