yes there is flattenImages but how to use it? It takes few images but i have one.

- clone 1,3 -compose subtract -composite -background gray50 -flatten

First i subtract image 3 from 1, then i adds background50 to image 1(subtracted) and what about flatten. It flats image 1(subtracted) with image 3?

Can anybody tell me how to do -flatten and -background in Magick++:

Code: Select all

-background gray50 -flatten

I was looking in MagickCore::CompositeOperator but i didn't find flatten operator. Something like backgorund i found, but how to do gray50?

Can anybody tell me how to write this line in cpp?

Code: Select all

-clone 1,3 -compose subtract -background gray50 -flatten

I can to a subtract:

Code: Select all

Image img1;
Image img2;
img1.composite(img2,0,0,ModulusSubtractCompositeOp);

but how to do a rest o line:

Code: Select all

-background gray50 -flatten

I'm trying to do as you said using composite, 50% of script is done, now i have a problem with adding noise. I've found there is function:

Code: Select all

Image.addNoise(MagickCore::NoiseType)

but i'd like to add my own noise like noise=1. Is there any function to add specified noise?

Next problems, now i need to divide by center pixel like:
/ p{64,64} ' \) \
but composite gets whole image not a value of pixel, and also what is the function for mod:
to do something like this:
mod(u + v + 0.5, 1.0), u, v are my images

convert image1 image2 -fx 'u*v ' result.png in command to the same as: Magick::Image test("test.png"); Magick::Image kernel("kernel.png"); test.composite(kernel,0,0,MultiplyCompositeOp); test.write("result.png"); But i found that there is no division composite operator...

still stuck on this images multiply. Don't know how to change command expression to c++ code

QuantumOperator doesnt work, it looks i need to use image.fx bu how to set std::string as parameter. I need this to rewrite FFT multiply command line script to c++ Magick++ app.

I have compiled with HDRI and quantum 8bit. I'll try it at home, thanks.

Code: Select all

convert finalImage -fx 'firstImage * secondImage /1.00 ' .

I think something like that

Hi would anybody explain me how in Magick++ do multiply and division like this line: -fx 'u*v / p{64,64} ' u,v are Images and p{64,64} is a number. In my code i have: Magick::Image u;//somewhere filled with data Magick::Image v;//filled with data double p=1;//this is p{64,64}; Magick::Image result; ...
