Thanks very much, and now, i have another problem: i use the following codes to get a specified output with transparent background. But the background is not transparent overall, it has a corner with gray color. Is there something wrong of the code?
Code: Select all
Image image( filename );
image.artifact("distort:viewport","540x960");
image.virtualPixelMethod(Magick::TransparentVirtualPixelMethod);
image.distort(PerspectiveDistortion,16,point_4,false);
image.write("distort.png");Thanks very much. I have found the problem. I corrected my code as follows, it is work for me.lq634254672 wrote: ↑2018-07-07T08:48:00-07:00Thanks very much, and now, i have another problem: i use the following codes to get a specified output with transparent background.
