Batch resize & other questions?

[DOK]

This is related to this thread. I'm looking for resize functionality like this: 
1. The ability to take a single image, (PNG transparent/opaque or JPG) and specify a range of sizes to resize to (e.g., 512x512, 256x256, 50x50…….20x20, etc.)
2. BATCH resize those images AND have the newly batched images retain the dpi of the original image.
3. It would be great if it could also include a user-defined rename of each new batched image that matches its new size (e.g., icon_512, or icon_20x20) as part of the batch process, but that is not as critical as steps 1 & 2. 

 

To date, I’ve been unable to find anything with this kind of functionality. Photoshop, Corel, and a host of other web-based apps or freeware apps don’t seem to do it. The closest I found was a web site https://derivv.com/ - which allows for #1 above, but it doesn’t retain the dpi of the original image through the batched results. 

Right now with Paint.net I take the original image, 1) resize it, 2) rename it, 3) go back to the original image , 4)resize to the next size in the list, and 5) so on and so on... This way I can retain the dpi form the largest image all the way down to the smallest, but needless to say it's time-consuming and prone to mistakes.

 

Any Paint.net plugins that currently do this? Or any other products you know of that do it? I’d greatly appreciate your feedback.

Hey there @DOK & welcome to the forum

 

I've split your post out of the old thread and into this new one. The previous thread was over a year old.

 

1. Not possible AFAIK. The Icon filetype plugin comes close, but the sizes are fixed. As is the file format.
2. & 3. Nope. No batch file functionality.

I'm not saying it will, but have a look at IrFanView.

I believe G'MIC-QT can do that though you would need to code it and I don't feel like making a sample code for you to work from. Same to ImageMagick.

 

Two forums I will refer you to

https://www.imagemagick.org/discourse-server/

https://discuss.pixls.us/

 

The bottom one refers to G'MIC-QT though you can ask for ImageMagick there. Ask your G'MIC-QT or ImageMagick question, and you'll get your answer.
