FTP connection to view BMP files

[benlee]

I am trying to retrieve a bmp file and display it using any of the image viewers but am having trouble. Is there a way to get the Image Viewer node to retrieve from a non-local location (i.e. FTP connection).

I have also successfully connected FTP to list files/folders then Path to String which is then fed to image reader (table), but that is no good.

Any help is appreciated.

Hello @benlee,

and welcome to KNIME Community!

Based on following two topics I would say Image Reader and Image Reader (Table) nodes both support reading from ftp. You just need proper URL format.

Image Reader Problem in KNIME 3.6.0

Hey guys, I have a problem when trying to use an older workflow (created using KNIME 3.4.2) in KNIME 3.6.0. The Image Reader (Table) node is unable to read from a remote location. I attached a screenshot to this post, as well as the corresponding lines from the log file. One note: the List Files node works just fine with the exact same remote location. So I think it is more of a KNIP problem than a KNIME problem. Cheers, Marc [Image_Reader_Remote_Location]KNIME Log File.txt (87.6 KB)

problems reading images

Hi Matthew, Thanks for your post.  Regarding (1): We hoped to have this fixed with our latest KNIME Image Processing release. Which version of KNIME Image Processing are you running? Regarding (2): Yes, reading from URLs is supported for FTP, KNIME and HTTP. Which kind of error are you experiencing? Can you post the error message and maybe the KNIME log? Best, Christian

Maybe something worth adding into node description.

Hope this helps!

Hi Ivan,

I’ve fed the URI but have been getting this type of error. I’ve tried manually inputting URI as a string as well as using the path to uri node, but it seems it’s having difficulty with the files. Any suggestions

Thanks,
Ben

Hello @benlee,

unfortunately can’t help you no more. Could still be incorrect format or some configuration issue with FTP or bug in KNIME. May @gab1one can share some information about this one?
