如何使用ImageMagick缩小gif图像的尺寸? [英] How can I reduce the dimensions of gif images with ImageMagick?

问题描述

magick.exe convert <flags>中的哪个标志会减小图像的尺寸?

What flag in magick.exe convert <flags> will reduce the dimensions of my image?

这是我正在使用的命令:magick.exe input.png[0] -depth 8 -type Grayscale -dresize 400x300.

This is the command I'm using: magick.exe input.png[0] -depth 8 -type Grayscale -dresize 400x300.

源图像文件名后的[0]表示要剥离所有动画gif的第一帧.

The [0] after the source-image filename is meant to strip the first frame of any animated gifs.

如何减小输出gif大小?我的文件大小太大:我的输出必须小于100k.除了减小尺寸以外，任何其他方法也都可以使用.

How can I do reduce my output gif sizes? My file sizes are too large: my outputs need to be less than 100k. Any methods other than reducing the dimensions are also welcome.

推荐答案

convert test.gif -fuzz 10% -layers Optimize result.gif

添加-fuzz 2％可以产生更好的优化效果，但是效果仍然不是很好.在-fuzz 15％时，它将帧优化的差异隔离到我之前提到的可见色带更改. 在25％的差异几乎只是文字更改.

Adding a -fuzz 2% produced a better optimization, but still not very good. At -fuzz 15% It isolated the differences for frame optimization to just the visible color band changes I noted before. At 25% the differences were almost to just the text changes.

最后在30％的模糊因素下(忽略低于该数字的颜色变化，它是否已优化为仅文本变化?

Finally at a massive 30% fuzz factor (ignore color changes below that figure, did it optimize to just the text changes.
