我已经有一个脚本可以执行此操作，但它使用 MS Word 和 DOCX 文件。但是，我被要求在无需安装 MS Office 的情况下使其工作，因此我一直在玩写字板和 RTF 文件。

我已经看到粘贴到 RTF 文档中的图像在 RTF 代码中被转换为某种类型的 HEX。

有没有办法将该图像自动转换为 RTF HEX 字符串？因为那时我可以将该字符串发送到 RTF 文件内容。

TIA

仅插入图片的示例 RTF 代码：

看起来写字板总是将图片转换为 .wmf 格式（wmetafile8在 RTF 中），但对于 .PNG 和 .JPG 文件，这似乎不需要。

下面的演示仅限于图像类型PNG，JPG

# This example uses a .jpg file
$imagePath = 'D:\Test\test.jpg'

$rtfType = switch -Regex ([System.IO.Path]::GetExtension($imagePath).TrimStart(".")) {
    'png'   { 'pngblip' }
    'jpe?g' { 'jpegblip'}
}
# get the image dimensions
$pixelSize = ([System.Drawing.Image]::FromFile($imagePath)).Size
$width  = $pixelSize.Width
$height = $pixelSize.Height
$twipsW = $width * 15  # pixels to twips
$twipsH = $height * 15

# load the image file as bytes
[byte[]]$imageBytes = [System.IO.File]::ReadAllBytes($imagePath)
# convert the bytes to hex string, split on 78 bytes per line
$hexImage = [System.BitConverter]::ToString($imageBytes).Replace('-','') -split '(.{78})' -ne '' -join [environment]::NewLine

# create the image in RTF format
# IMPORTANT: the top line MUST end in a space character!
$rtfImage = @"
{\pict\$rtfType\picw$width\pich$height\picwgoal$twipsW\pichgoal$twipsH 
$hexImage
}
"@

# merge in RTF document
$rtfContent = @"
{\rtf1\ansi\ansicpg1252\deff0\nouicompat\deflang3081{\fonttbl{\f0\fnil\fcharset0 Calibri;}}
{\*\generator Riched20 10.0.17763}\viewkind4\uc1 
\pard\sa200\sl240\slmult1\f0\fs22\lang9\par
$rtfImage
\par
\pard\sa200\sl276\slmult1\par
}
"@

# save as file
$rtfContent | Set-Content -Path 'D:\Test\completed.rtf'

在写字板或 MS Word 中打开时，您应该在其中有图像：

在此处输入图像描述
