Question

I'm making a complement for QGIS3, how can I export the map I'm seeing in the window to .PNG using Plugin Builder. Without having to go through Print Composers.

I assume you know how to create a plugin by Plugin Builder 3. If so, briefly, delete the code lines under def run(self): line in main file of your plugin and just add the following code under def run(self): line.

self.iface.mapCanvas().saveAsImage("your_path/file_name.png")

If you don't know how to create a plugin by Plugin Builder 3, firstly please refer to Qgis Plugin Builder page.
