Re: Need help REMOVING pixels that don't exist in BOTH images

Oh! Oh my lord. Okay! I get it now! Let me change a few things with the source images to be closer to real world cases and I'll see if it works the way I hope it does! Thank you! I think you've helped me before with something similar with color curves!

Re: Need help REMOVING pixels that don't exist in BOTH images

That's VERY close to right! I wasn't clear. I've had a REALLY tough day today. Been trying to repair garden hoses to get water to crops, and every hose I repair, somehow, magically, causes another hose somewhere down the line to fail, I'm about 200 ft from water, so you can imagine the day I'm havin...

Need help REMOVING pixels that don't exist in BOTH images

I have 2 images, Sometimes three. For simplicity, we shall name them Math1, Math2, and Math3. I have found a way to do the exact thing I want to do. However, it leaves pixels half alpha, and it doesn't give as consistent of a result as I'd like. I'd like it to leave no alpha pixels behind, on a blac...

I would do it like this:

Code: Select all

magick at8XHKF.png -channel RB -threshold 75% -channel G -evaluate set 0 +channel out.png
Perfect! All I had to do is change 75 to 99 and I got exactly the result I wanted. THANK YOU SOOOO MUCH! You're a LIFE-SAVER!

Much love!

How about "-range-threshold" for those channels? See http://www.imagemagick.org/script/command-line-options.php#range-threshold and https://imagemagick.org/discourse-server/viewtopic.php?f=4&t=34604 . Thanks for the prompt reply! This seems to only do black and white as far as I can tell. Maybe I d...

Setting an image color curve for three channels individually?

I have the following Curve that I would like to apply to an image by using ImageMagick. This curve removes the green by setting the slope of the Green to 0/0. Then the RED and BLUE follow the points, 0,0 254,0 255,255 https://i.imgur.com/eO2t2jx.png I was able to get the first part. Removing the gre...
