Could you please help me.

Is there macro can check if an image is all white or fully transparent?

The Input will be path like this C:\Users\ehab.ali\Desktop\New folder\1000012.png in Column "A"

The output will be in Column B >> Status : White or Transparent or Color?

Thanks;

Hi,

I haven't done this before but you may be able to use TransparentBackground to check if the image has any transparency

https://docs.microsoft.com/en-.....background

 

I'm not aware of any function to check if an image is all white (or just one color) .  If one doesn't exist then I can only think that you'd have to check each pixel and you could do this with Windows API calls

Hi Marsil,

Have you tried to write the macro?  I'm happy to help you out if you get stuck but I'm sorry I don't have time to write things from scratch.  The best way for you to learn is to give it a go 🙂

Regards

Phil
