Setting fontWeight/fontStyle/lineSpacing doesn't work

Here is my code:

Code: Select all

	Magick::Image image( Magick::Geometry( 700, 700 ), Magick::Color( "white" ) );
	
	image.font( "verdana" );
	image.fontPointsize( 70 );
	
	image.fontWeight( 900 );
	image.fontStyle( Magick::ItalicStyle );
	image.textInterlineSpacing( 0.1f );
	
	image.textGravity( MagickCore::CenterGravity );
	image.draw( Magick::DrawableText( 0, 0, "Hello\nworld!" ) );
	
	image.write( "images/testImage.png" );
And that's my output:
Image
As you can see there are no any weight, style affect. And there's no also any interlineSpacing effect. Why does it work like this?

For drawing text, as opposed to other methods, I suppose you should use methods on http://www.imagemagick.org/Magick++/Drawable.html such as DrawableFont.

Well maybe. But for what purposes developers created those methods such as fontStyle(), fontWeight(), textInterlineSpacing()? :)

Code: Select all

Magick::Image image( Magick::Geometry( 300, 300 ), Magick::Color( "white" ) );
	
std::vector < Magick::Drawable > textArr;
	
textArr.push_back( Magick::DrawablePointSize( 70 ) );
textArr.push_back( Magick::DrawableTextInterlineSpacing( 0.1f ) );
textArr.push_back( Magick::DrawableGravity( MagickCore::CenterGravity ) );
textArr.push_back( Magick::DrawableFont( "verdana", Magick::ItalicStyle, 900, Magick::NormalStretch ) );
textArr.push_back( Magick::DrawableText( 0, 0, "Hello\nworld!" ) );
	
image.draw( textArr );
	
image.write( "images/testImage.png" );
The same output as listed above...

Well I can use another ttf file for setting italic style of setting new font weight but what to do with the TextInterlineSpacing? It doesn't work in both cases...

There is no -style. But in command line, you can use -interline-spacing. See http://www.imagemagick.org/Usage/text/# ... ne-spacing. That should autowrap with caption, but with label:, -annotate, and -draw, you likely need to put in newline character (\n) where you want it to wrap.;

Interline spacing of zero means "no change". A value of 0.1 will increase it by 0.1 pixels, which I can't see. Try:

Code: Select all

image.textInterlineSpacing( 50.0f );

I ran into this as well. In my case it was because imagemagick on osx homebrew is built without fontconfig. Therefore it is unable to find the italic/boldface fonts.

The problem was fixed after: brew reinstall imagemagick --with-fontconfig
