Batch renaming and resizing via command line

[riptorn]

Hi,

Just wondering if someone could help with settting up a batch rename and resize that I need to do.

The files are in one folder and export to another folder.
The start as product-1000-imagenumber.tif and need to export to product-500-imagenumber.jpg.
I currently sharpen by 1 in the batch.
There are 6 imagenumber parameters (different images for the same product).

Not sure if this is possible by batch.

I have read a few posts about this and haven't found an answer. As a future suggestion being able to run a batch (including all parameters being saved) would make the program so so easy to use for non-programmers like myself.

Thanking you in advance,

Nathan...

Hi Nathan,

I hardly understand what you are looking for.

About command line to resize, rename, look in IrfanView help file. There are many examples.

Thanks for replying. I can do everything in command line except can't figure out how to do the renaming like in the gui batch as we label all our products with productcode-1000-1.tif, -1000-2.tif, etc. and resize them the new file has to be named productcode-250-1.jpg, productcode-250-2.jpg, etc.

Hope this is a little clearer. Thanks so much.

Hi Nathan,

Did you try to use wildcards? (See help file for examples).

Hi,

On a similar note:

I have thousands of images to convert and rename. The original is 257x193 pixels and I must save a bigger version of 400x300. The quality is badly affected by this and I thought of trying to sharpen up the images in the process to remove some of the fuzziness caused by stretching the image to a larger size.

Here is my command (for a single file):

i_view32.exe C:\a.jpg /resize=(400,300) /resample /jpgq=100 /convert=C:\b.jpg /sharpen=20

But the sharpening doesn't do anything... I noticed in the help file that the sharpen example is used by itself (and actually opens up an instance of IrfanView) -- does this mean that sharpening cannot be applied through the command line? If so, are there any other alternative to sharpening up a fuzzy resized image (using command line parameters)?



Thank you very much and thanks a lot for an amazing product.

Try starting a batch operation with the selected files from the Thumbnail view or try the /advancedbatch switch from the command line.

Hi Alain,

Save after sharpening (/sharpen before /convert).

I thought my situation would be a little easier, but I can't get the rename part to work. The command line I am using is

i_view32.exe C:\test\*.jpg /resize=(65,65) /aspectratio /resample /convert=c:\test\*_thm.jpg

The problem is that it doesn't add the "_thm", it overwrites the source file.

Syntax

Yes, your situation is easy, but I think the wildcard (*) is throwing it off. Read Text/Pattern Options in Help, but be careful. I would use:

i_view32.exe C:\test\*.jpg /resize=(65,65) /aspectratio /resample /convert=c:\test\$N_thm.jpg

And if you want to do a folder of mixed formats, try:

i_view32.exe C:\test\* /resize=(65,65) /aspectratio /resample /convert=c:\test\$N_thm.jpg

But, if you want to preserve their original formats, use:

i_view32.exe C:\test\* /resize=(65,65) /aspectratio /resample /convert=c:\test\$N_thm$O

Enjoy!
