English term or phrase: offset to
It is part of an image's properties. Is there any other way to explain what "offset to JPEG SOI" means? I have several translations for offset, but I am not sure what to chose in this case. Thanks in advance!

Thank you, Jack, and thank you specially to Kenneth, for my doubt regarded the term "offset" and I have seen it really means distance (movement, displacement) to the start of image

offset with respect to


Explanation:
I would imagine it must mean 'offset with respect to..' or 'offset from...', though on the face of it, this sounds like a slightly odd way of expressing it.

However, as I don't even know what JPEG SOI is, and I can't imagine what units those 2548 are in, I'm afarid I can't be any more help than that...

disagree  Alexander Demyanov: While "with respect to" may be understood for any direction, it's definitely not "from". There is nothing "odd" in the expression as it talks about bytes preceding those of an jpeg image.

  -> If an offset is 'from' one point, it is perfectly logical that it is 'to' when viewed from the reverse point of view...

agree  Clauwolf: right

  -> Thank you.

agree  Alexander Demyanov

  -> Thank you.

agree  Tony M: Ah, now THAT makes a lot of sense! Though I still don't see why it's 'to' and not 'from'...?
32 mins
  -> I don't know anything about the technicalities, but I imagine it is "offset towards" rather than away from.

agree  Dave Calderhead: Dusty - the "offset to" provides a [white] margin before/around the image

  -> Thank you.

agree  Ken Cox: To help the asker: the offset is the 'distance' from the nominal start of the image to the actual imagery, stated here in units of pixels (probably). That effectively produces a white margin, as Dave pointed out.

  -> Thanks. That helps me too.

agree  Nikos Mastrakoulis

  -> Thank you.

agree  Alfa Trans (X)

  -> Thank you.

agree  Jörgen Slet: Ken - definitely not in pixels. As I understand, SOI is the point where standard image-related information begins, its offset is its distance in bytes from the beginning of a file. "White margin" is meant figuratively.
