Automatic upsizing in CS3?
      #651470 - 04/05/2008 01:30

Hi

I'm trying to find a short cut to a very boring job.... can anyone help?

I regulary have to upsize collections of images for submission to a stock agency. Opened files have to be 48mb minimum. I've tried using genuine fractals for this job which works fine. However, I want to automate the process as I get very bored loading the image, running the upsize, waiting, then converting to 8bit and saving....

I can run a script to load the image, upsize to a given picture width in GF, then convert and save out. However, I have to then separate landscape and portrait images to input the know width or height respectivelly so as to end up with the 48mb min file size. It gets worse for images which are of varying aspect ratios as the height/width to input in the script is different for each image therefore can't be automated.

Is there a way of upsizing where I can enter a 'target' file size in the script and it does the donkey work of calculating the height/width needed for each image thereby allowing me to write a script to automate the whole process?

Here's hoping....!

Cheers

Why get the minimum size needed when "not smaller than" is what you need?

The humble and free IrfanView can batch resize & convert so long as the target size is fixed. It even does a reasonable job - not as good as Genuine Fractals, but maybe good enough. You would have to seperate out the landscape, portrait and near-square images but that sounds a hell of a lot less tedious than what you've already worked out.

BTW if you upsize in increments of about 10%, repeatedly until big enough, using IrfanView or PSE the end result is practically indistinguishable from a single application of Genuine Fractals. In any event you may find that a judicious application of unsharp mask works wonders.

Image processor in CS3 will do the job without any need to separate horizontal/vertical.

Yes - I see that. I wasn't sure that the quality achieved would be as good as using genuine fractals. Anyone compared the two methods - much difference?

One of the pro mags compared GF to Photoshop a couple of years ago (ie when Adobe introduced the improved interpolation methods in CS). The difference was marginal: very slightly in favour of Fractals when viewed at large sizes I think.

Sorry I can't give a more personal view, but as virtually all methods are recommended by someone or other it'd be pretty worthless anyway. What I can say is that I use Image Processor for Alamy very regularly - no problems.
