Auto resize with macro

[joe-the-way]

Hello, thank you all for you help

I try to make an auto resize macro for generating an image that fit 300px in height and auto scaling the width in consequence, but i cannot fill in the macro script the width as "auto", is there a way to do it ?

Yes, I am looking for the same. To create a macro that will resize an image to a fixed width while preserving the aspect ratio.

Is there any other way to do this?

I don't think that is possible in PD itself at the moment. Alternatives: if you need it for batch conversion, think about using ImageMagick, it is really not that complicated to write a batch file. Or if you just want to do it some images you could try a tool such as AutoHotkey to open the resize dialog, fill in the height value for you, and press enter. (PD reacts well to ahk keystrokes I find).

As Macros can be edited in a text editor, perhaps PD could in the future support say * or auto as values to be edited manually in Notepad for some type of actions so it would offer such flexibility in cases where it is really desired such as here. so after editing part of the macro would look like this (note auto at width)

	<processEntry index="1">
		<ID>Resize image</ID>
		<Parameters><version>3</version><width>auto</width><height>300</height>....</Parameters>
		<MakeUndo>1</MakeUndo>
		<Tool>-1</Tool>
	</processEntry>

Hello all. I apologize for not noticing this discussion sooner.

I believe I can add this feature to PhotoDemon's batch converter relatively quickly. I will report back in the next few days (possibly sooner) when I've got something concrete to share.

thank you

Thank you. I did look at ImageMagick as a possible solution, but if PhotoDemon can do it even better.

It could also be applied to the Batch Processing feature as well as the Resize tool.

I used to use Adobe Fireworks many years ago (now discontinued) and that had the ability to batch process images by setting a max width and max height. All images would then be resized to fit within those dimensions proportionally without altering aspect ratios.

I have been looking for a replacement for Fireworks for a while now and PhotoDemon is by far the best in my opinion. Perfect for what I need. :)

I believe the image tool https://www.nyam.pe.kr/dev/imagine/ (freeware) can do this, use batch conversion, add resize action, keep width to 0 but set height to 300, it will the resize the height to aspect. You can test safely by choosing a different output folder or other image format so you don't loose data.

Okay friends, a new PhotoDemon nightly build is now available. This build brings three new "fit" options to the first page of the File > Batch operations > Process wizard:

The three new options are:

• fixed width, preserve aspect ratio
• fixed height, preserve aspect ratio
• max size, fit within, preserve aspect ratio

If you set a target size of "500x500", here's how image files would look after your batch process completes:

• fixed width, preserve aspect ratio
  All images now have a width of 500; height will vary to preserve original aspect ratios.

• fixed height, preserve aspect ratio
  All images now have a height of 500; width will vary to preserve original aspect ratios.

• max size, fit within, preserve aspect ratio
  All images now have either a width or height of 500; their other dimension will be <= 500, at a value that preserves the original aspect ratio.

I hope this provides a way to accomplish the batch resize operations described earlier in this thread!

sounds good thank you very much

That is absolutely fantastic, thank you. Downloaded and works great. This will be invaluable to me. Great stuff!
