Resizing Multiple Images Using a Macro Fails

[apollo_de]

Hi,

didn't find a solution by searching the forum ... the problem:

I've multiple images, for simplicity say two, with different pixel sizes (w x h):

1. 4032 x 3024 px
2. 3600 x 2700 px

I want to do a simple batch operation, to just reduce the height to say 1080 px, keeping the aspect ratio.

Trying to write a macro failed, because the images differ in size and the menu Document > Resize Document ... > ... doesn't allow to leave one of the Size fields (width/height) unpopulated, so that every image would have a height of 1080 px and an adapted width. 

Currently one of these two images will always have an unwanted aspect ratio.

I'm just wondering because Photoshop Elements has the ability to leave either the width or the height field free and all images are "batch-resized" properly, keeping the correct aspect ratio.

I don't want to change Apps all the time ... is there a AP solution, did I miss something?

TIA, regards,
apollo_de

It can be done in a macro but you don't need one

Use...

File > New Batch Job

Just set the height to 1080 and leave the "A" (Aspect Ratio) setting ticked

Thanks carl123,

I knew that. The idea behind was, that there were far more tasks I wanted to be done by the macro - resizing was just the first part of the procedure ...  Didn't want to break the process into parts.

Any other ideas welcome ...

Cheers,

Resizing using a macro is very complex, because most methods you'll think of remember the final size of the image you used when creating the macro, and thus it won't work well for images with different sizes. There have been a few complex macros created that can resize images that have different sizes, For example, @carl123 posted this one previously. You can probably find others by searching the Resources forum.

But if you can do it via the batch job itself you may have better results and it will be simpler. In any case, I would make that a separate macro, rather than trying to have one macro that does resizing and other actions. Developing and using the  macros will be much simpler that way.

If you really need to use a macro to re-size, then you need to use Filter > Distort > Equations. I wrote a macro to resize to a fixed maximum height or width here. You could easily adapt this to your needs.

Hi John,

thanks for the suggestion. I will have a look at that and then decide ... 

At first glance the suggestion of Walt seems more attempting and an easier way to go to me.

Walt has good arguments and a simple solution (carl123 also suggested it): "In any case, I would make that a separate macro, rather than trying to have one macro that does resizing and other actions."

I think my request is answered - no further comments needed. 

I thank all of you for fast and great support!
