Export megapixels
I'm trying to set up an export recipie -- I'm used to functionality in a competing product -- I'm somewhat confused that the scale options are missing the megapixels option. This seems like such a fundemental and important option to have in there, especially when outputting files of wildly diferent cropped aspect ratios.
Am I missing something, or is it really absent?
If it is, feature request?

I think you're looking for the Scale dropdown menu in the Export Format and Size tool.
Select Width x Height and you can define the size of your image in pixels. Megapixels simply describe the horizontal and vertical measurements in here.0 -
There isn't a way of specifying a certain size in megapixels. When you select an export recipe, it will show you what the expected size will be, but it is very approximate, and may vary from image to image for the same recipe, depending on the image content.

Hi,
Having tested this, it appears that the "width x height" option sets an upper limit on both dimensions, and downscales the image to fit. "Dimensions" is the same but the 2 axes are interchangeable. (The other options are self-explanatory and simpler)
None of these options do what I’m after.
If I want an output that is 4MP, and I have 2 images that are:
A: square – I want an output of 2000x2000
B: 4:1 aspect ration – I want an output that is 4000x1000
If I put 2000x2000 into the width x height option, I end up with:
A: 2000x2000
B: 2000x500 – not good.
If I put 4000x1000 into length x height, I get:
A: 1000x1000 – not good.
B: 4000x1000 (or if the aspect ratio is the other way 1000 x 250, which is fixed by “dimensions”)
MegaPixels is a measure of “how much image you have” and therefor seems like a basic needed option here.
@Ian Wilson: I don’t understand your comment; the actual content should have nothing to do with the pixel sizes. It will affect the file size when using a compressed filetype. Unless I’m missing something.

JR Peterson - my comment was the result of not reading the question properly! Apologies.

I´m curios, what is the use case for fixed MP regardless of aspect ratio?

I have to submit photos to various commercial organisations which specify e.g. "image to be no larger than X megapixels." If you have a large number of photos of differing crops having to "dimension fix" each file individually can be a dog of a job
Maybe the product management people know this use case but in case they don't I think (no, I know) it is valuable to add it to the core description of the feature request.
