Re: How to work with FX in Magick++?

This line:

Code: Select all

testImg.fx( "200" );
also leads to the broken image. In my case this only one line which is worked for me:

Code: Select all

testImg.fx( "rgb(255,255,0)" );
in this case I see a yellow image.

Getting a bunch of pixels leads me to segmentation fault...

This simple code: Magick::Image *imagePtr = new Magick::Image( "images/horse.jpg" ); Magick::Pixels view( *imagePtr ); Magick::Quantum *pixels = view.get( 0, 0, imagePtr->columns(), imagePtr->rows() ); unsigned int r = 255 * QuantumScale * ( *( pixels + 0 ) ); gives me segmentation fault.

The rotate primitive rotates subsequent shape primitives and text primitives about the origin of the main image.
Well, so can Magick++ rotate object around a specified anchor point of that object?
What's the origin of the main image? Is it the center of it?

Re: How to draw rotated image using DrawableCompositeImage and DrawableRotation?

Why the rectangle changes its place? Is this normal behaviour or some sort of a bug?

The horse has rotated once, by 75 degrees. That is what you asked for.

I can't see how much the rectangle has rotated.
But why the rectangle has the another place on the second image? I didn't change its coordinates...

What does that mean? Please show the result.
It means that the system rotates it once and then seems it rotates it twice
