Display base64 images

[Jhon Doe]

Hi everyone

i'm new in filemaker, i'm using filemaker 17 and currently i'm involve in a proyect but i have a problem that i can't resolve, maybe someone of you have had the same problem.  

I'm saving images in base64 format in a database to show them in a layout with web viewer,that doesn't has any problem, the problem is that i'm using a portal and i didn't know that portals don't support web viewer. I have to display those images but i can't remove the portal since i didn't do that layout and it has scripts using it along with the portal, is there a way to show images saved in base64 without use web viewer? (I've already tried to use container field but it only show a "?" image 😓 )

 

My English is not the best but I tried my best ,Thanks for your help

What exactly have you tried? A calculated container using the Base64Decode() function should work.

Hi, I tried that code Base64Decode($(ImageInBase64),"name.png"), but since the $(ImageInBase64) is an image in base64 the container only shows me a "?" image.

I am afraid I don't understand your explanation. You should have a text field containing base64 encoded image data. Then a calculation field (result is Container) =

Base64Decode ( YourTextField ; "name.png" )

should display the reconstructed image (assuming it was a .png image originally).

sorry for my explanation, yes you right i've done that, but I want to show the image itself, and with this code, the container shows me a png icon and not the content of the text field containing base64 encoded image data. I don't know whether  I 'm doing something wrong when I pass the data to that command or my data in base64 is bad encoded or damaged.

Base64Decode ( YourTextField ; "name.png" )

Thank you for your help, I've figured out a way to resolve this problem, I've save the images that i need to show directly in the container field without use the text encoded in base64.

I don't know that either. But it does work for me, so you can paste your data into the attached file and see what you get.

Thank you once again, I've seen what was my mistake, you have to remove the line : data:image/png;base64 !!!!

I am not aware of any such restriction, and I doubt it exists. A text field can contain up to 10 million characters - and the specs say nothing about any limits when processing it (except, of course, available memory).

yes, I was on mistake that was the first thing I thought because i didn't realize what  the error was.
