PlaneMylinder中有一个选项可以扭曲imageMagick来制作像下面的图像吗? [英] Is there a options in Plane2Cylinder distort of imageMagick to make a Image like bellow?
问题描述
当我使用Plane2Cylinder失真时,我得到了如下图像。但我希望效果像第二张图像。请仔细阅读我的代码。
When I used Plane2Cylinder distortion I got Image like below. But I want the effect like second image. Please go through my code.
local nelem = 1 -- number of args
local arg = ffi.new("const double[?]", nelem, {100})
-- local methos = ffi.new("const int", 15)
return handle_result(self, lib.MagickDistortImage(self.wand,13, nelem, arg, 1))
ffi.cdef([[ typedef void MagickWand;
typedef void PixelWand;
MagickBooleanType MagickDistortImage(MagickWand *wand, DistortMethod method, const size_t, const double *args, const MagickBooleanType bestfit);
更新:
for fred's脚本我用下面的命令
UPDATE: for fred's script I used below command
bash -x ./cylinderize.sh -m vertical -r 366.34955984688 -l 188.179 -w 16.6667 -p 23.428692808745 -n 96.097053534591 -e 1.75 -a 0 -v background -b none -f none -o -86-80.8315 single_color.png single_color.j.png
以下是我修改过的图片。
Below is my modified image.

看起来失真参数只有视野值设置(100),但缺少中心X& Y值。
Looks like the distortion arguments only has field-of-view value set (100), but is missing the center X & Y values.
Plane2Cylinder只是所需失真的一半。主题(马克杯)不是一个完美的圆柱体,因此需要应用额外的轻微失真(可能是透视)以匹配足够的音高。
Plane2Cylinder is only half of the distortion needed. The subject (mug) is not a perfect cylinder, so an additional slight-distortion (perhaps Perspective) will need to be applied to match the suffice pitch.
