Add background to the text using Magick++

Question

Im trying to add red background under the text using Magick++. My simple code is:

Magick::Image img( Geometry(800,200), Color("white") );

img.strokeWidth(12);
img.font("Helvetica");
img.fontPointsize(font_size);

img.draw(Magick::DrawableTextUnderColor(Magick::Color("red")));
img.draw(Magick::DrawableText(25, 25,  "Some text") );

img.write("file.png");

It prints text OK, but the text does not have red background. Current result is this:

However, I would like to have the text with background, something like this (background photo shopped for the example)

Answer 1

This should work. Instead of drawing things one-by-one, make a list of Drawable items, and than draw everything at once:

list<Magick::Drawable> to_draw;

to_draw.push_back(Magick::DrawableText(25, 25,  "Some text"));
to_draw.push_back(Magick::DrawableTextUnderColor("red"));

img.draw(to_draw);

• Here is a solution of your problem,

   Image img(Geometry(800, 800), Color("white")); img.font("Helvetica"); img.fillColor(Color("firebrick")); img.strokeColor(Color("red")); img.draw(Magick::DrawableText(25, 25, "Some text") ); img.write("text.png");
