Macro distorting proportions

[nachoespino]

Hello. I created a macro that first resizes the image to 1,000 pixels on the long side and then cuts the canvas to 660 pixels. The thing is that when I do the process manually on an image it does it fine, but when I run the macro it distorts the proportions in almost all cases. Why does that happen? I am attaching the two macros (one for vertical and one for horizontal) in case it helps. Thanks in advance.

Macros record the final numeric results, and thus actions like that kind of resizing can only be applied to images of the same aspect ratio.

You will need to use the Filters > Distort > Equations function to do that kind of resizing. Luckily, other users have already provided macros for that which you could use directly or as a model

Thanks for your answer, @walt.farrell. I'll check those macros

Why not try using File > New Batch Job... to resize the image(s) to 1000 pixels and have the Batch Job run a macro which cuts the canvas to 660 pixels.

@Old Bruce that looks like an easy solution, I'll give it a try and post the results. Thanks!

@Old Bruce resizing with the batch job is working fine, but not the cropping

Assuming your goal is to resize images to 1000w or 1000h then crop to the middle 660px of the height/width
If all of your images have the same aspect ratio then you have a chance with Photo macros otherwise forget it
Use new batch job with
1000 in the width box
1000 in the height box
Leave A ticked
Run this and all your images will be 1000w or 1000h. Note that this will upsize small images in which case use min(1000,w) and min(1000,h) respectively

Now you need two macros, one for landscape, one for portrait, use the outputs from the batch job to create these
For the landscape images it just needs to crop the picture to 660 high and this should default to cutting out the centre 660px
I would then apply some unsharp mask as sharpening is generally required after resizing. Do similar for the portrait images but crop the width
Until Photo gets scripting then I think this is about it

Or you could use imagemagick which is excellent for batch work and will deal with different aspect ratios, just write some gibberish like this
magick input.tif -resize 1000x -gravity center -crop x660+0+0 -unsharp 0x0.4 output.tif
magick input.tif -resize x1000 -gravity center -crop 660x+0+0 -unsharp 0x0.4 output.tif

You can use these commands one at a time or else in a powershell file where you can find width & height and run the appropriate command. Otherwise use Python and it'll also work on Macs
