Still trying to explain. I have to use a Gimp 2.6 in a Widows VM, Not able to install in Ubuntu 10.04, some required libraries were pulled a couple of years ago.
Keeping it simple
Use your 1772 x 2953 @ 300 ppi - that is the correct size for a 150 mm x 250 mm print size.
Use ImageMagick convert without the -density switch, I might have had it in the wrong place.
Open the PDF in Gimp. The default settings uses 100 ppi like this: https://i.imgur.com/THVlIY0.jpg
Change the resolution to 300 ppi The reported size, ignore it or do a mental conversion to millimetres. https://i.imgur.com/4Jos0AP.jpg
Various ways to check the actual properties. The image size in pixels is top of the image window (1) Use Image -> Print Size to check size in mm (2) and the print resolution (3) https://i.imgur.com/MNQpXoS.jpg
