imagemagick:创建一个.png文件，它只是一个实心矩形 [英] imagemagick: create a .png file which is just a solid rectangle

问题描述

我想创建一个纯色的.png文件.

I want to create a .png file which is just a solid color.

使用ImageMagick做到这一点必须很容易，但我无法找出问题所在:

This must be easy to do using ImageMagick but I can't figure out the problem:

C:\tmp>convert -size 8x16 -stroke black -fill black -draw "rectangle 0,0,8,16" black.png
Magick: missing an image filename `black.png' @ error/convert.c/ConvertImageComm
and/3016.

推荐答案

显然可以有更多选择，例如边框等，但是如果您只想要宽度x高度为给定十六进制颜色的图像，那就很简单了

Obviously there can be more options, like borders and etc, but if you just want an image of width x height of a given hex color, it's pretty straight forward.

这里是制作100x100的深红色固体图像的全部步骤:

Here's all it takes to make an 100x100 image of a solid dark red:

convert -size 100x100 xc:#990000 whatever.png
