Convert Magick::Image to cv::Mat

你离开我真会死。 提交于 2020-01-02 08:21:28
问题 I am trying to convert an image loaded in from a GIF via Magick++ into a cv::Mat . I have already converted from cv::Mat to Magick::Image but cannot seem to find how to pull the data out of an Image in Magick in order to load it into a Mat. What's the best way to do this? For reference, in reverse: Convert cv::Mat to Magick::Image 回答1: Updated Answer This is the best I can get it, I think! #include <opencv2/opencv.hpp> #include <Magick++.h> #include <iostream> using namespace std; using

Send object with openMPI

问题 I'm using magick++ library to manage images. I want to distribute my algorithm using openMPI, is it possible to send objects? for example in my code I have Image image(imgName); int w = image.columns(); int h = image.rows(); PixelPacket *pixels = image.getPixels(0, 0, w, h); Can I send pixels with MPI_Send or Scatter of whatever? if yes with which datatype? 回答1: In general, unless you have a special library that's doing packing for you, it's never possible to send a specialized object in MPI.

Image Magick++ equivalent to convert -fill

孤人 提交于 2019-12-24 11:51:14
问题 I have a convert command that I need to translate into Image Magick function calls. convert.exe bar.jpg -fuzz 40% -fill "rgb(53456, 35209, 30583)" -opaque "rgb(65535, 65535, 65535)" foo2.jpg I was wondering if anyone could give me an example of the methods I need to apply to get the same effect? Thanks for any help! 回答1: The documentation for Magick++ is pretty clear, but there's a lot more examples using c & MagickWand. For the most part, -fill is just setting a color attribute that can be

ImageMagick static compilation with another project gives linker errors

问题 I've downloaded the ImageMagick source, compiled the wizard to create a Visual Studio solution for static linkage, and included the static library Magick++ project in my sample project (code below). I've also added a dependency on that project and included the .lib file in the solution, nothing helps. #include <Magick++.h> int main() { Magick::Image image; bool test = image.isValid(); return 0; } This gives several linker errors, such as: unresolved external symbol "__declspec(dllimport)

问题 I'm trying to push a Node app to heroku, but I am using imagemagick-native and it seems that Heroku is having an issue with Magick++ - I've tried using custom build packs but can't seem to find one that supports Magick++.

问题 I'm trying to use ImageMagick Magick++ for a C++ Project in VS2010. I installed the Library from here: klick Then in my Project, I added c:/program files/ImageMagick-6.6.6-Q16/include to the include folders. Then I tried to use Magick++ with this code: #include <Magick++.h> void main(int argc, char ** argv){ InitializeMagick(*argv); } But this does not work! VS2010 returns the following errors: error LNK2001: unresolved external symbol "__declspec(dllimport) void __cdecl Magick:

Getting pixel color with Magick++?

只谈情不闲聊 提交于 2019-12-18 16:30:37
问题 I've already asked this question, but that was about FreeImage . Now I'm trying to do the same thing with ImageMagick (to be more correct, with Magick++ ). All I need is to get the RGB value of pixels in an image with the ability to print it out onto the screen. I asked this in the ImageMagick forum, but it seems there is nobody there. :-( Can anybody help, please? 回答1: Version 6 API Given an " Image " object, you have to request a " pixel cache ", then work with it. Documentation is here and

ImageMagick result differ from Magick++

萝らか妹 提交于 2019-12-13 18:40:12
问题 I have 3 images: source.jpg, saturated.jpg and mask.jpg , I want to blend the source.jpg and saturated.jpg using the mask.jpg . When I use the ImageMagick's convert command: convert source.jpg saturated.jpg mask.jpg -compose over -composite result.jpg I get this result. But when I do the same with Magick++: Magick::Image source,saturated,mask; source.read("source.jpg"); saturated.read("saturated.jpg"); mask.read("mask.jpg"); source.clipMask(mask); source.composite(saturated,0,0

问题 Good day, here is my code #include <iostream> #include <Magick++.h> using namespace std; using namespace Magick; int main(int argc, char **argv) { InitializeMagick(*argv); Image image; try { image.read(argv[1]); } catch( Exception &error_ ) { cout << "Caught exception: " << error_.what() << endl; return 1; } int x = image.columns(); cout<<"your picture's width is "<< x << "px"<<endl; return 0; } I use KDevelop(which uses CMake as builder), when I try to compile the app, it throws me an error

ImageMagick C++ API Output 16-bit grayscale png?

China☆狼群 提交于 2019-12-11 01:34:09
问题 I'm linking to ImageMagick via the Magick++ API. I'm attempting to take uint16 data and output it as a 1024x768 1-channel 16-bit grayscale PNG. The output I get from the following is an RGB8 PNG. The image contents are correct besides the formatting. gray16_view_t u16view = ...; uint16_t* data = interleaved_view_get_raw_data(u16view); size_t length = sizeof(u16) * u16view.width() * u16view.height(); Magick::Blob u16Blob(data, length); Magick::Geometry size(u16view.width(), u16view.height());
