How to use DrawableSkewX/Y?

I test it using following code: Magick::Image testImg( "images/horse.jpg" ); testImg.strokeColor( "red" ); testImg.fillColor( Magick::Color( QuantumRange, QuantumRange, QuantumRange, 0 ) ); testImg.strokeWidth( 2 ); testImg.draw( Magick::DrawableSkewY( 50 ) ); testImg.draw( Magick::DrawableEllipse( ...

Re: What's the fastest method for drawing one image over another?

I've checked out these methods and they are give me following results on the same image: >>>>>> composite: 0.096247 sec. >>>>>> DrawableCompositeImage: 0.758551 sec. Seems that DrawableCompositeImage more than 7 times slower than composite one :) I've checked it using 100 attempts for composite and ...

What's the fastest method for drawing one image over another?

Now I use:

Code: Select all

image2.compose( image1, x, y, Magick::OverCompositeOp );
Is there a faster way for drawing one image over another than the compose? I really need it :)
Image2 is always bigger than image1. Image1 places at the center of the image2.

As the documentation says: DrawableCircle double originX_, double originY_, double perimX_, double perimY_ Draw a circle using the stroke color and thickness using specified origin and perimeter coordinates.

Thanks for the explanation! Now I've got it. I believed that there is a easier way for achieving it :)

Re: Problem with Shadow. It doesn't show

I see the white label only. The shadow is the current background colour. You haven't set this, so you get the default, which is white. You get what you asked for: a white shadow. If you want to put a shadow behind the original image, you need another step, which is show (in command-line form) at ht...

Re: How to use textGravity?

I have a strange problem. Why this code doesn't work? std::cout << "Size: " << img5.columns() << "x" << img5.rows() << "\n"; img5.textGravity( MagickCore::CenterGravity ); img5.draw( Magick::DrawableText( 100 - ( img5.columns() / 2 ), 0, "Some text!" ) ); It returns me: libc++abi.dylib: terminating ...

Re: How to use textGravity?

Well... instead of it I've just developed a formula :)

Code: Select all

img5.textGravity( MagickCore::CenterGravity );
img5.draw( Magick::DrawableText( 100 - ( w / 2 ), 200 - ( h / 2 ),  "Some text!" ) );
it places a text at the 100x200 by center of it. (anchor point at the center of a text).

Re: How to use textGravity?

Hm... yeah looks like it works like this :) That's not what I was looking for :) Is it possible to align the text at the center of given coordinates? I mean something like: anchorPointX = 0.5f, anchorPointY = 0.5f. When I use that command: img5.draw( Magick::DrawableText( 100, 200, "Some text!" ) );...

Re: What's the fastest method for accessing to pixel color?

Is that right that in case of my RGB image: Magick::Image *image = new Magick::Image(); image->size( Magick::Geometry( _imgWidth, _imgHeight ) ); image->backgroundColor( Magick::Color( "white" ) ); image->erase(); I get 4 bytes per pixel: Magick::Pixels view( *image ); for ( unsigned int j = 0; j < ...
