Voronoi' Morphology Distance method

Greetings,

I read with interest about the new Voronoi' Morphology Distance method that "will fill in holes using the nearest non-transparent edge pixel".

Can someone please show me an example how to use this feature?

Thank you!

Re: OpenCL

Thank you!

So what would be involved for making the general use functions (like the MagicWand API) take advantage of that?

Constrain text to vector shape?

Is it possible to constrain text to flow within a given vector shape?

An example shape may be a circle or rectangle.

Any suggestions are greatly appreciated!


Thanks.

Re: CMYK Halftone Effect

I think if we could get variable dots based on the brightness of each channel (as discussed on the other thread) then apply those dots using the overlay composite operator, it would be 100% legit. For my purposes though, I am just trying to closely emulate the effect, and I think fixed dot sizes wil...

Re: CMYK Halftone Effect

Thanks Anthony, looks good!

I will play around with your scripts. I think we pretty much have got it!

I used 108, 162, 90 and 45 degrees for CMYK respectively which are the defaults for Photoshop's CMYK halftone.

Re: CMYK Halftone Effect

I think a figured out a way to achieve this. I did the following in Photoshop, but I think it can all be done with IM. The only thing I am not sure about is converting the image to CMYK (from RGB) and extracting each of the channels, since I haven't yet done any CMYK conversions with ImageMagick. I ...

Re: Porting convert command to MagickWand

BEAUTIFUL! Thank you very very much! I owe you a brew. That did it! I had tried specifying the blur wand as the first wand for the composite argument, but I didn't try doing the linear stretch after the composite! So that is what the +swap does! :o Thanks again! Do you have an iOS device? If so I wo...

Re: Porting convert command to MagickWand

Thanks, but actually doesn't help.

The code I have is working, I think the issue is I don't know what the equivalent composite operators from the convert command are.

CMYK Halftone Effect

Greetings, I have looked at all of the available halftone presets, and I can't figure out how to make something similar to a true CMYK halftone.

Reduce to points?

Greetings,

I could be wrong, but I think I remember reading of a way to reduce areas of an image to a single pixel using ImageMagick.

I am trying to achieve something like the results of the right hand image:

Any suggestions would be greatly appreciated!

Reading as GrayScale

Greetings, I am reading in a grayscale image, but it seems like somehow the wand is reading it as an RGB image. The reason I suspect this is because if I run this: MagickLevelImageChannel(magick_wand2, GrayChannel, (0.5f * QuantumRange), 0.6666f, (0.8f * QuantumRange)); It apparently is only doing t...
