I am having an interesting aspect ratio issue with Calibre and comics input.

I have a PRS-950 replacing a PRS-600.

On the PRS-600 I left "keep aspect ratio" unchecked since I wanted maximum readability. With the slightly larger screen on the 950, I did some test conversions with "Keep aspect ratio" checked. I also changed my page setup to Sony Reader 900 (assuming it matches the 950 as well) for both input and output profiles.

My original images were 823x1200 or roughly 0.685 aspect ratio

Math tells me the new ones should be 600x875 to match. Instead Calibre (CBZ to EPUB) converts them into 600x999 images.

They seem slightly "stretched" vertically to me, but that could just be me used to the stretched horizontal results on the prs-600.

So long story long, is Calibre not keeping aspect as requested? Is it padding to reach 999 pixels, or is it trimming whitespace off the size and scaling correctly? Or something else I'm just too dumb to figure out?

Thanks!
