    Default Batch converting raw images to png

    Hi,

    I'm trying to convert several raw images to png images. This works fine and all, however if I convert via batch, I need to enter the height and width for each file (I'm aware raw doesn't specify them), which really slows things down.
    If I convert via command line, irfanview seems to always use the last value entered, which is not an option for me, since my images differ in size.

    Is there a way to specify the size via command line?

    Use the Batch dialogue, advanced options dialogue. There you have an option to resize by percentage. I don't see that option in the command lines i_options.txt, but perhaps /advancedbatch will do it.

    Do one converstion using the batch dialogue to set the required values, then use the /advanced batch switch to /apply Advanced Batch Dialog options to image (from INI file)
