Image Input

[bradley_slaughter]

I have a folder with a series of .png file extensions.  I want to read those images in and join them to my data via the filename.  When I try to read the files in using the image tool I receive the following error:

Error: Render (14): Error parsing Image: Not a PNG file

To my knowledge the files are PNG.

Does anyone know of a way to troubleshoot this problem?

Thanks for the help!

If you right click and look at the image properties, what does it say? Is there any other file in the folder with the same naming convention, but a different file type?

[bradley_slaughter]

It identifies the file as a .png.  All files in the folder have a the same naming convention and file type.  I get the error when I try to pull in a single files as well.  I have tried a few things already: changing the file type to a different extension, downloading a random .png from the internet to test.  Downloading a random png works.

How have the images been created? I'm wondering if they were corrupted somehow. Can you open them in other programs?

[bradley_slaughter]

To test your thought, I opened the file in GIMP and "overwrite .png".  When I completed the overwrite, I was able to bring the picture in.  There are 564 pictures though, so that is not a sustainable method.

That sounds painful. At this point I would recommend opening a support ticket to see if your images are an edge case that needs to be corrected, since they can be opened in other programs.

Hi Team, 

Is there a way in Alteryx designer to read the data from the Image and store them in Rows and columns ? 

[StephenR]

This would be best asked as a new question @sudhar46, but I would use the Python tool (you'd need to create custom code) to read the pixels into a dataframe then bring that into Alteryx.

Yes i knew that i will have to finally end up with Python tool only but wanted to check if there are any other possibilities (without coding can this be done) . Thanks Stephen for your response.
