Currently our mobile app generates this error:

convert.exe: no decode delegate for this image format `TMP' @ error/constitute.c/ReadImage/501.

convert.exe: no images defined `C:\Users\T8F1E3~1\AppData\Local\Temp\9f226b00-5cdb-4ae1-a1dd-1c47caceba7a.tmp' @ error/convert.c/ConvertImageCommand/3212.

How can we fix it and why it can happen?

Thank you.

Hello Mykola,

I would say that this problem has to do with some command that is being sent to the executable that has an incorrect format.

You could do a simple test in a web application to validate if it is a problem with the component (not working with mobile, even if being called from server side), or if it is a problem that the operation you're trying to do is not working at all.

A search for the error showed lots of problems related to this, most of them related to improper command line syntax (if it is this, it would happen both in mobile as well as web).

What is the operation you are trying to do? Crop? Resize?

Hello Eduardo,

We have two convert actions with different options - to resize and to crop square.

Most of the time all is working both on web and mobile app. But sometimes we have above mentioned error. I will try to replicate it on regular basis.
