Export current shown image frame (red rectangle) translated and with selected camera resolution

[n1k0m0]

Is your feature request related to a problem? Please describe.
Exporting the red image rectangle (image frame) of currently set telescope, camera, lense,etc.-combination as a translated image with the resolution of the selected camera.

Describe the solution you'd like
a) Simple solution would be a special screenshot button that copies the translated and (camera-width/height)-scaled image into the clipboard.
b) More sophisticated solution would perform also steps of (a) but generates a fit-file that also includes coordinates and rotation and stores that on the harddrive.

Describe alternatives you've considered
My current workflow is to create a screenshot of the full application and then manually cut, rotate, and resize it using photoshop.

Additional context
I use the "alternative method" as descirbed above for photo frame planning. I screenshot the complete stellarium app with appropriate camera, telescope, etc settings. Then, I cut the red rectangle, rotate it and resize it to the correct camera resolution. Then at the beginning of an astro-photo image session, I plate-solve the created image in Ekos to slew to the shown position, rotate the camera appropriately as indicitated by ekos, and thus create the exact photo frame I previously chose. Works well, but a direct export (with coordinates and rotation) would be really helpful.

Hello @n1k0m0!

Thank you for suggesting this feature.

Given the fact that we have no solution to rotate the view and don't intend allowing this, I doubt this is going to ever happen.

You don't need to rotate the view for that. You proably have the angle of the rotation of the red rectange ("astro camera view"), I assume. Thus, creating a screenshot and then rotate the screenshot (based on that red rectangle rotation angle -- of course reverse) and cutting the screenshot could be the solution.

creating a screenshot and then rotate the screenshot

Sure, this is a quick-and-dirty solution, but the text labels will be turned in the resulting screenshot.

If we don't care about black corners and screenshot geometry, the scripting function to take screenshots could be made even more complex by a rotation argument that is applied by some QImage::rotate() function (if available. I am away from my dev PC.) Very ugly, and fits the needs of one person...
Maybe you can just write a script tha first makes a screenshot and then calls some external program to rotate.

Can you pinpoint me to the source code position. Then I would have a look at the code on my own and try to adapt it to my needs :-)

The screenshot code is in StelMainView::doScreenshot(). The red frame is rendered in Oculars::drawSensorFrameAndOverlay() (which is inside the Oculars plugin). Oh, BTW, don't forget that this frame in general has curved sides in all projections except perspective.

Thanks, I'll have a look
