Alpine Linux 上的 imagemagick wmf 支持 [英] imagemagick wmf support on Alpine Linux

问题描述

我正在 Alpine 上安装 imagemagick，它选择了 7.0.10 版本的 imagemagick.

I am installing imagemagick on Alpine, which picks up 7.0.10 version of imagemagick.

我的主要用途是将 WMF 转换为 PNG.但是 convert sample.wmf sample.png 给出错误

My primary use is to covert WMF to PNG. But convert sample.wmf sample.png gives error

convert: no decode delegate for this image format `WMF' @ error/constitute.c/ReadImage/572.
convert: no images defined `sample.png' @ error/convert.c/ConvertImageCommand/3322.

根据 https://www.imagemagick.org/script/formats.php，我也安装了libwmf，但没有解决问题.

As per https://www.imagemagick.org/script/formats.php, I also installed libwmf, which does not resolve the issue.

identify -list 格式 |grep WMF 不返回任何结果.

你很幸运！GraphicsMagick 可以在 alpine:latest 上做到:

You are in luck! GraphicsMagick can do it on alpine:latest:

现在进行从 WMF 到 PNG 的转换:

Now do the conversion from WMF to PNG:

gm convert sample.wmf result.png

原答案

我认为您无法做到这一点，至少使用 ImageMagick...

I don't think you'll be able to do that, with ImageMagick at least...

我尝试在 alpine:latest 上安装 libwmf，然后从源代码安装 ImageMagick，但它拒绝使用 libwmf v0.2.12

I tried installing libwmf on alpine:latest and then installing ImageMagick from source and it declined to use libwmf v0.2.12

所以我检查了 ImageMagick 需要什么，它需要 libwmf v0.2.8.2.

So I checked what ImageMagick requires and it wants libwmf v0.2.8.2.

所以我尝试了 alpine:3.8 它可以安装 libwmf v0.2.8.4 但 ImageMagick 仍然不接受(xxx/缺少 ipa.h).

So I tried alpine:3.8 which can install libwmf v0.2.8.4 but ImageMagick still wouldn't accept that (xxx/ipa.h is missing).

所以我回顾了 alpine:3.3 和 alpine:3.4 并且它们没有 libwmf.

So I looked back to alpine:3.3 and alpine:3.4 and they have no libwmf.

所以我尝试了 alpine:3.5 并且它是与 alpine:3.8 相同的 libwmf 版本

So I tried alpine:3.5 and that was the same libwmf version as alpine:3.8

TLDR;alpine:3.5 的 libwmf 对于 ImageMagick 来说太新了，alpine:3.4 根本没有 libwmf.

TLDR; alpine:3.5's libwmf is too new for ImageMagick and alpine:3.4 doesn't have libwmf at all.

注意:我在 libwmf 的包和版本nofollow noreferrer">这个 网站.

Note: I found the packages and versions of libwmf on this website.
