Re: using -define png:color-type=2 add grey row to bottom

sorry, on windows 10, IM version 7.0.5-Q8
I tried the code above, and it does replace the color with trans, but the final png is Indexed Color.

using -define png:color-type=2 add grey row to bottom

I have a bunch of 16x16 pixel button images, whose "background" color was 192,192,192. I need to replace that with transparency, and save as RGB png. The replace is easy using: (step1) magick mogrify -fuzz 0%% -transparent "rgb(192,192,192)" "C:\CAD_Support\Menu Images\*.png...

BIIIINGOOOOOO! Dang, guess we know why the word "magick" in the name, you pulled that out of a hat like a pro. Unbelievable, good catch. You have a paypal name? or email me at jmaeding **at** hunsaker **dot** com with location to send check if you prefer. Or amazon gift card, you name it. ...

Re: Trim images with polygon and combine

I actually do have all the coordinates, I just meant I want to use the original image corners for the distort. I am actually doing what your approach says, something is going wrong if more than two images are merged though. Look at this, I merge 2 with this code: "magick.exe" ^ ( "log...

Re: Trim images with polygon and combine

well, the problem with that is I know where the images get placed based on corners of the untrimmed image. That is why I don't want to modify the size of the originals, just mask out pixels outside my polygons. I reread what the meaning of "+distort tries to fit..." meant, and think it doe...

Re: Trim images with polygon and combine

Here is a real situation with several maps I want to stitch. I am zoomed out a bit but these are not square to eachother, and the clips are not simple rectangles but may have 6 or more points involved. https://s13.postimg.org/41o8oc7s7/ex2.jpg I'd think if I can figure out how to add images to posts...

Re: Trim images with polygon and combine

Lets try this.
Image

On the lower image with all rotated stuff, the final image would be a rectangle of course. Any extra area added would be white.
Does that help a bit?
thx

Re: Trim images with polygon and combine

I would love to post pics, but have to relearn how to add them to this forum. I think the simplest way to explain what I want is I have 4 images that I know their unclipped locations, as well as the clipping polygon coords. I want to clip them and then composite to one image. They must end up exactl...

Re: Trim images with polygon and combine

The more I study and test, the more I think I am doing it correct. I did a test to just tile unclipped images, worked perfect: "magick.exe" ^ "logo.jpg" ^ ( "logo.jpg" -alpha set -virtual-pixel transparent +distort affine "0,0 -123,0 0,118 -123,118" ) ^ ( &quo...

Re: Trim images with polygon and combine

oh, I see the problem. I thought +distort meant "expand virtual canvas as needed", but that is incorrect. Instead +distort tries to fit things somehow. From the IM web page: "The other form of the operator, "+distort" (Added to IM v6.3.5-7), will attempt resize the distorted...

Re: Trim images with polygon and combine

I see what you are doing with the mpr:, but not +25+25. Why would you do that in this situation? I would think you might only reset the 0,0 of canvas if expanding it in negative directions, but you did positive. I made some progress on my previous tests. I realized my trim coords were off, so fixed ...
