Hey! So removing the for command and just leaving the ImageMagick command works with out a problem. Right now I am working around this by breaking up what I want to happen into a couple steps instead of one for loop: convert %name%%ext% -brightness-contrast %bright%,%Con% -level 0%%,%max%,%gamma% %n...

So I can remove the error following your advice and using: for /f %%o in ("convert %name%%ext% -gravity center -crop 50%%x50%%+0+0 -brightness-contrast %bright%,%con% -level 0%%,%max%,%gamma% -format '%%[fx:maxima*100]' info: ") do set maxN=%%o But now my variable 'maxN' is equal to the wo...

Hello! So in a normal command prompt this line evaluates just fine: convert filename.tif -gravity center -crop 50%x50%+0+0 -brightness-contrast 4,-5 -level 0%,100%,1.0 -format "%[fx:maxima*100]" info: However, in a batch file and within a for loop, the '-5' in -brightness-contrast causes t...

Here is a tiff scan of the color target I will be using and what the scan would hopefully look like: https://drive.google.com/file/d/0BzGl-rJtgJ-VTS1zYUtxeWE2dFk/view?usp=sharing and thank you for the responses! This all sounds good. I am not intimate with the compare program or the -statistics func...

@snibgo

are there any examples you may be able to point me to that use standardDeviation? Im going to have to research that and an example or something close to it would be great.

thanks!

@fmw42 Thanks for the reminder! So i want to produce a scan of the xrite color target. then crop down the image to a specific number of patches. I guess i was wondering if I would be able to locate the target in the scan because the user may not always keep the target square or in the same place. So...

Is it possible to use IM to locate and recognize a color target , like an XRITE ColorChecker? I can do this with ArgyllCMS but I want to be able to create a new image from some of the color patches on the target. which is to say Argyll uses a scan recognition file (.cht) to somehow locate the color ...

Hello! So i am working with DNG files and would like to convert them with a linear curve rather than the defaults defined for dcraw in the delegate file. I know how to manually change the delegate file and make this work. This can be explained in this post: http://www.imagemagick.org/discourse-serve...

This was incredibly useful. Your explanation has helped a lot. Im still working on a final solution and running some tests but will update when I can.
Thank You!

Thanks dlemstra!

Thank You for your responses. I've read about -evaluate before. I have tried editing the file used for the vignette correction and know i can change the results that way, but want to know if there is a better way. I will research evaluate again and try it out. In the mean time here is a link to the ...

Thank You for answering fmw42! I will provide a link tomorrow when i have access to the files again.
