This document provides instructions for installing and using the ImageMagick++ library in C++. It summarizes that ImageMagick++ allows manipulating images using C++ and provides the following key capabilities: - Installing ImageMagick++ on Linux using package managers or compiling from source - Loading, manipulating, and saving images using the Image class - Drawing shapes and text onto images using drawable classes - Manipulating images using methods for filters, editors, and adjustments - Rendering text using fonts, including installing Korean fonts - Using STL containers like lists to group drawables The document includes code examples for common tasks like reading/writing images, applying effects, and drawing shapes and text onto images. It provides

Image

9. try {
Image img1("local.gif");
Image img2(Geometry("100x100"),
32, "GIF");
Image img3;
img3.read("local.jpg");
} catch (Exception& e) {

}

10. Image manipulation methods...
Filters...
addNoise, blur, charcoal, ...
Editors...
erase, floodFillColor, zoom, ...
Adjustments...
level, levelChannel, ...

11. Image read & write
Image img; Blob blob;
img.read("mypic.jpg");
// Manipulations...
img.magick("PNG");
img.write("mypic.png");
img.write(&blob);

12. Drawable classes...
Providing i/f for image or text for Image::draw()

Drawable

13. Image img(Geometry(500,500),
Color("White"));
img.draw(DrawableCircle(100, 100, 10, 10));
img.draw(DrawableRectangle(200, 200,
10, 10));
img.display();

14. Using STL library!

15. Image img(Geometry(500,500), Color("White"));
std::list<Drawable> dl;
dl.push_back(DrawableStrokeColor("Red"));
dl.push_back(DrawableStrokeWidth(5));
dl.push_back(DrawableFillColor("Green"));
dl.push_back(DrawableCircle(100, 100,
10, 10));
img.draw(dl);
img.display();

16. Text Rendering...

17. Korean fonts installation...
Local
$ mkdir ~/.fonts
$ cp *.ttf ~/.fonts
$ cd ~/.fonts
$ fc-cache

18. Korean fonts installation...
Global
$ su -
$ cd /usr/share/fonts
$ mkdir my_ttf ; cd my_ttf
$ cp ~/.fonts/*.ttf .
$ cd my_ttf
$ fc-cache

19. Image img(Geometry(500,500), Color("White"));
std::list<Drawable> dl;
dl.push_back(DrawableFont("맑은 고딕",
NormalStyle, 800, NormalStretch));
dl.push_back(DrawableText(0, 0,
"세상아, 안녕?", "UTF-8"));
img.draw(dl);
img.display();
