Get Picture cropping info
schungx opened this issue · comments
I have a spreadsheet with images that have been cropped.
I can see the following information regarding the cropping:
Picture.blip_fill -> BlipFill.source_rectangle -> SourceRectangle { t, l, r, b }
The measurements within SourceRectangle
are all strings, which store a simple text representation of numbers.
How do I calculate the cropping offsets from this? Is there any documentation I can look up?
I can see that t
= top, l
= left, r
= right and b
= bottom... The numbers (represented as strings) do not quite match anything though...

Thank you for contacting us.
Sorry, I don't have the specs on the SourceRectangle values.
According to this page, it seems to be a percentage.

Thanks a great deal.
Just knowing it may be a percentage already makes loads of sense.
It certainly looks like a percentage with three decimal digits, coded as a five-digit integer. Not sure why it is in text format (perhaps to have other values such as "auto" or something?)
