Macros: Interrogate Image Size, Apply Variables

[skm-300]

Let me start by saying how wonderful PD is! It has transformed batch editing images for use on my Wife’s e-commerce website, keep up the excellent work.

I’ve successfully created several macros that do the relatively simple task of cropping to the extremities of an image, then resizing the image before finally resizing the canvas to allow for a standardised border.

My challenge is that the source images are not always equal in width/height. The recorded Macro(s) fix the width & height to constant values, causing stretch/skew issues on ‘non-square’ images.

I’ve been working around this by creating multiple macros by category, editing the width/height in notepad to account for ratio maintenance.

Is it possible to pull in the width & height of the image after the crop, then use these variables to apply the resizing? My wish is as follows:

—————————
Get width w
Get height h
Get Ratio (of w:h) r

If w > h then w = 450px & h = (w X r) else
h = 450px & w = (h X r)
—————————

This would reduce my number of required macros significantly.

Side question:

• Can the file name be interrogated to decide upon a variable? (e.g. If file name contains ‘Hammer’ & ‘Core’ then Wand selection tolerance is 20 else 99

Happy to post the side question as a new discussion if preferred.

Look forward to any responses you have.

Adding "If then else" "for loop" etc might be quite a feat to add. I would look for "outside" solutions by sorting the images first, then start the processing. So sorting the image by size and move them to a sub-folder and then process them with the correct macro, there are various options of course.

Some ideas:

1. in File Explorer you may be able to see the dimensions, right click on the column header and select dimensions. Other file managers will offer similar options either directly or with plugins/addons.
2. you can write a batch file and use exiftool.exe - you already have a copy in App\PhotoDemon\Plugins\exiftool.exe. You can generate a text file with the info https://superuser.com/questions/925068/script-to-get-images-in-folder-with-dimensions-printed-to-a-txt-file

Many thanks for your input!

I was hoping for something a little more sleek, but I am greedy.

I did consider filtering the source images into subfolders to apply separate macros but even fell down attempting that. I need the ratio of the images & the ‘dimensions’ column just shows the image size in px. I could, for example, apply the same rule to an image that was 2400x1600 as one that is 1200x800. Others share my frustration that Windows is unable to display image ratios. I keep hitting brick walls when thinking of other way of doing what I’m hoping to do… It’s frustrating but I’m enjoying the challenge!

I did find an if then else xml function within xsl… Example linked below:

There are more ways to skin a cat as they say :)

1. https://www.xnview.com/en/ has a column option for "ratio" - it's freeware afaik
2. If you happen to be a Total Commander user (a shareware dual pane file manager, https://www.ghisler.com/) there are plugins that can show, with, height and aspect ration in a column - you can see a screenshot here https://totalcmd.net/plugring/wdx_ImgSize.html - note there are several other Total Commander "clones" that are freeware and that have (partial) support for TC plugins.
3. If you're not adverse to some "programming" there is the https://imagemagick.org/ toolset which I believe has options to display/find aspect ratios so you can sort them that way.

Awesome stuff!

Gives me a lot to play with in the coming week!

Many thanks for your efforts.
