我想利用《图像》,在左边添加一个透明的梯度,并有权形成一个形象。
我可以产生以下形象:
convert -size 100x100 gradient: -function Polynomial -4,4,0 -distort SRT 90 gradient.png
它希望:
我还能够把这一形象 compos在我所希望的形象之上:
composite original.jpg -compose Multiply gradient.png final_image.jpg
所有这一切都处以罚款。 我的问题在于,我如何改变这种越权主义的图象?
感谢!
以此为主
convert input.jpg -alpha set -virtual-pixel transparent -background red -channel A -blur 0x34 -level 75%,100% +channel -flatten final.jpg
在我的案件中,我:
在<代码>梯度:选择后添加 com-相左的颜色:
convert -size 100x100 gradient:white,blue -function Polynomial -4,4,0 -distort SRT 90 gradient.png
注:<代码>-功能 转播渠道,梯度的这种颜色也是原样。
