Hello,

in order to use the report generator of Matlab I created the needed template sheet with a relative path to an

image which shall be loaded.

All works fine as long as the image's full path does not contain a blank. Thus, after moving everything to a new

location (the relative path stays the same) the image can't be found because of blanks inside the full path:

ERROR: Image not found. URI: file:///D:/NewLocation/Path%20With%20Blanks/relPath/imagefile.png

The blanks are replaced by '%20' and the full path makes no sense, anymore.

Any suggestions?

Many thanks,

Timo

The blanks should be replaced with %20 . What is being displayed is a URI, and URI's use percent encoding

https://en.wikipedia.org/wiki/Percent-encoding#Current_standard

The generic URI syntax recommends that new URI schemes that provide for the representation of character data in a URI should, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values.

The table of unreserved characters is shown further up on the page, and does not include space, so space characters in URI should be encoded as %20.

Thanks for your comment.

Unfortunately I can't replace the blanks by %20 in the template file because I do not know the final full path.

This is why in the template a the relative path is stated - which is sufficient. The Matlab report generator creates the full path internally and seems to be unable to deal with the blanks.
