Re: draw circle radius

Another way to look at it is that from the center of the center pixel to the center of the far right pixel is exactly 3. So if you consider the "circle" perimeter to have one pixel thickness, then the distance from the very center of the circle to middle of the perimeter pixel is 3.

Re: draw circle radius

I think that the actual radius value is added to the center pixel to get to the circle perimeter. 0 1 2 3 So from 0 you add 3 more to get to the radius of 3, which is the 4th pixel. Or perhaps better you can think of it as from 0 to 1 is distance 1, 1 to 2 is distance 1 and 2 to 3 is distance 1. So ...

Re: Montage: files with different dimension, but right proportions

... is there any way to force resize only for height ?
Yes, but that would distort your image.

Code: Select all

convert image -resize x1000! result
See ! at http://www.imagemagick.org/script/comma ... p#geometry

Re: Montage: files with different dimension, but right proportions

Images 1 and 2 do not have the same height, so +append will add white space to make them both the same height. Similarly for 3 and 4. Thus your images are not the right proportions to append the way you want. You may want to resize the image to have the same heights. With imagemagick 6, you will hav...

Re: Extract image from PSD file

That message is to be expected, since PNG does not allow a grayscale image to have an RGB colorspace. It is just a warning. Since your image has extra alpha channels, IM cannot see them and must do it vs color. If you have other PSD files with just one not fully opaque alpha channel, then IM should ...

Re: Extract image from PSD file

As was said before in the previous post, IM sees your PSD file as having a fully opaque alpha channel (alpha). It does not recognize the extra alpha 1 channel. So taking the first layer and processing it as follows, I can extract the alpha channel by making everything that is near the blue color tra...

Re: resize was successful but cannot decrease file size

You have a very large xmp profile in your image (Profile-xmp: 4081099 bytes). You also have increased the quality from 74 to 75, which is not likely a big deal. Try adding -strip to your command to remove the profile and other meta data. Or remove the xmp profile, via +profile "xmp". You also did no...

Re: Accessing raw image data

I do not use Magick.Net, so I will leave confirmation to him. But that is the way it is in the command line version of ImageMagick.
