How to export annotated polygon layer to the non-georeferenced extent of the original raster image

Hi all,

I am currently working on the Geotiff image for the historical Cadastral map. I annotated some Geo-referenced maps in the correct coordinate system in vector-format lines and polygons. Now I want to export these annotations to the same resolution and the same extent as the scanned raster image inside the Geotiff file. I need pixel-to-pixel alignment of the original raster image and the annotation to train some DeepLearning networks. Besides, it would be better to keep the original raster image as there will be information loss if I project both map and annotation in the correct coordinate system.

For example, you can have a look at the above image. Currently, I can only export the annotated mask layer in the geo-referenced extent with the red bounding box. However, what I need is the labelled mask to be exported with the blue bounding box, so that the mask is matched with the original Cadastral map pixel-to-pixel, like in the image below. Do you have any idea to do that? Thanks!
