Darn, I was really hoping I could get away with not passing more arguments, but It's looking like I have to pass in '-Depth 1' for my mask and 'PNG32' for my 32 bit image instead of relying on 'PNG00'.

Thank you so much guys, hopefully we can figure out whats going on.

EDIT:
I'm also seeing it's converting 1 bit to 8 bit now:

"Why does it matter that your Windows tool is saying they are different? Does it affect your further processing in any way?" Yes, because I am trying to import the resized image back into a service (A bitmap service that we wrote) that will not allow me to import a 8 bit indexed image bac...

I don't understand what problem you are trying to solve. You have linked to two files. Exiftool says they are both palette files. So what? You have shown two screnshots. From what software? Relating to what files? They say one file is "Bit depth 32" whatever that means, the other is "...

Should I open a new question for this? If you run my code on your image and look at the actual bit depth you'll see it's been changed to 8.

So, I'm getting the exact same output when I preform -verbose but in both the properties and in my code it's been changed from 32 bit to 8 bit:

I'm not able to, it's already packaged and distributed, would this be the issue I am having with the PNG00? Are you getting the same issue with your convert?

You can use "-type" to prevent paletisation. But I would have to pass a type to my method, correct? I'm trying to stay away from passing arguments other than size and image name. You can find the images here: https://ibb.co/gurNQF https://ibb.co/eSaGkF Image: D:\z\TestLayer.png Format: PN...

Sorry, I understand the syntax for any of the flags so I did not think it would matter what versions or platform I am using. convert C:/test_512x512_32.png -resize 128 -unsharp 1.5x1.2+1.0+0.10 PNG00:C:/test2_128x128.png Yes I am converting a larger image to a smaller one, when I export, after doing...

I spoke a little too soon @fmw42, "It works" But not for 32 bit images, when I resize a 32 it drops the depth down to 8 bit (because its dropping the channels with the resize). Do you know if there is another flag, or a flag that would extend to 32 bit? I was hoping that I could get away w...

What is your IM version? C:/test.png -resize 128 -unsharp 1.5x1.2+1.0+0.10 png32:C:/test2.png This is not a valid command. If on IM 6, then it needs convert at the beginning. If on IM 7 it needs magick at the beginning. If you just specify PNG00:, then I believe it should not try to change your dep...

I'm currently resizing images and I ran into a problem of ImageMagic applying it's own bit depth (Not taking into account of the depth of image) so now I am using 'png32': $ C:/test.png -resize 128 -unsharp 1.5x1.2+1.0+0.10 png32:C:/test2.png Ideally I am looking to just read the images depth from t...

Thanks guys, yeah they are pretty much identical, literally the smallest differences.

No problem, can I output with dotgain? I know these images look almost identical but when you toggle through them in Photoshop you can notice the difference. It's not a huge deal at this point but just wondering if I can get the identical output. Photoshop output: http://i.imgur.com/fpdTHWc.png The ...

What version IM are you using? If fairly recent (since about v6.7.5), don't put "-set colorspace RGB". That says the image is linear RGB, which it probably isn't. Using: Magic.net 6.8.7 Removing colorcolorspace fixed it a little but I am still getting a little bit lighter of a image, do I...
