2 -In most cases, you will transform XML messages to other XML messages, or you will transform JSON or EDI messages in another of these formats. However, sometimes you want to perform an image transformation. With this image transformation you can transform images in certain formats to another format (i.e. png). This can come in handy when you want to standardize the image format before using it further downstream in your business application(s).

These commands can happen from the Deploy and the Manage phase. The two most noteworthy examples of the triggered command queue are the runtime dashboard functionalities and the message redelivery actions.

16 +This microlearning focuses on the command queue. The command queue communicates between the eMagiz portal and an eMagiz runtime.

14 -With image transformation, we mean transforming the raw data that represents an image to another image format.
18 +* Commands towards a runtime, for example, to retrieve runtime information in the runtime dashboard, are sent via the command queue
19 +* You can monitor the command queue the same way as any other queue within your model
20 +* The command queue is prominently used when accessing the [[Runtime Dashboard>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-deploy-runtime-dashboard||target="blank"]] and when using [[Message Redelivery>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.Message Redelivery.WebHome||target="blank"]]

26 +For example, when you navigate the Runtime Dashboard and click on a runtime, the eMagiz portal will send a command to the runtime via the command queue to retrieve the runtime state. So, for example, the same logic applies when you select a flow and stop it.

32 -When turning to the Create phase of eMagiz, we need to open the flow and enter "Start Editing" mode to add the component we need. For example, in the left panel, you can search for "Image". This will yield the following result.
