Uncalled-for format conversion
Hi, I recently tried to crop 9,446 images at once with the batch processing tool. I was using a script I saved form the last time I did something like this, but with modified dimensions. Once the job was finished all of the images had been converted to JPEGs. Now, I did not want that. I checked the script and the format output was set to PNG, as I intended. So my question is what went wrong. I don't want to try this again until I know it will work properly.

Maybe you see problem about save button resetting: Script conversion XBS: Changing after saving
Re: Uncalled-for format conversion
Yes, I've used the script before with no problems and I checked afterward and it was defiantly set to PNG.xnview wrote:After loading your script, output format is PNG?

Re: Uncalled-for format conversion
I've tried it, i load the script, format is on PNG, Go => output file is a PNG

Alright, before I try it again I have a question about PNG compression. XnView gives me the option to chose between compression levels 0-9. PNGs are lossless so if I set it to the highest compression I won't lose any image quality, will I? I mean, what's the draw back to using level 9 compression over the default, level 6? Would a higher level change it to an 8-bit PNG?

Yes it's lossless, it's the compression level used by zlibrondus18 wrote:Alright, before I try it again I have a question about PNG compression.
