我正在根据电子邮件的内容生成 pdf 文件，并且该电子邮件包含图像。但我想在该 pdf 中添加该静态图像。在 pdf 中添加静态图像的方法是什么？

这取决于您创建 PDF 的方式。通常（当绘制到 CGPDFContext 时）您使用普通的 Quartz 绘图函数来添加图像。

你可以这样做：

-(void) CreatePdf
{
   NSInteger currentY = HEIGHT; 

  NSString *logoFileName = @"logo.jpg";

  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

  NSString *saveDirectory = [paths objectAtIndex:0];

  NSString *logoFilePath = [saveDirectory stringByAppendingPathComponent:logoFileName];

  currentY = [self getAbsoluteY:currentY :70];

  UIImage *logoImage = [UIImage imageWithContentsOfFile:logoFilePath];

  CGContextDrawImage(pdfContext, CGRectMake(paddingLeft, currentY, 100, 70), [logoImage CGImage]);

}

-(NSInteger)getAbsoluteY:(NSInteger)currY: (NSInteger)space 
{
   return (currY - space);
}

You can do like this :

-(void) CreatePdf
{
   NSInteger currentY = HEIGHT; 

  NSString *logoFileName = @"logo.jpg";

  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

  NSString *saveDirectory = [paths objectAtIndex:0];

  NSString *logoFilePath = [saveDirectory stringByAppendingPathComponent:logoFileName];

  currentY = [self getAbsoluteY:currentY :70];

  UIImage *logoImage = [UIImage imageWithContentsOfFile:logoFilePath];

  CGContextDrawImage(pdfContext, CGRectMake(paddingLeft, currentY, 100, 70), [logoImage CGImage]);

}

-(NSInteger)getAbsoluteY:(NSInteger)currY: (NSInteger)space 
{
   return (currY - space);
}

我用PS和Word解决了类似的问题。这个简单的脚本打开 Word 并将图像插入到新文档中。然后您可以手动将文档另存为 PDF 或其他格式。这也可以自动化，但我更喜欢让 Word 打开以检查它并在保存之前进行少量编辑。

该脚本对于删除旧杂志很有用。只需将要保留的页面扫描到单个文件夹中的图像文件中，运行脚本，然后将文档另存为适用于 Kindle 的 PDF 即可。

$letterWidth = 612
$letterHeight = 792
$topMargin = 0
$bottomMargin = 0
$leftMargin = 0
$rightMargin = 0

function Main([string] $dir)
{
  $files = dir $dir
  $doc, $selection = OpenWordDoc

  foreach ($file in $files)
  {
    $par = $doc.Paragraphs.Add()
    $par.SpaceAfter = 0
    $par.Alignment = 1
    $pic = $par.Range.InlineShapes.AddPicture($file.FullName)
    ScaleImage $pic
  }
}

function ScaleImage($pic)
{
  $hScale = ($letterWidth - $leftMargin - $rightMargin) / $pic.Width
  $vScale = ($letterHeight - $topMargin - $bottomMargin) / $pic.Height
  $scale = [Math]::Min($hScale, $vScale) * 100
  $pic.ScaleHeight = $pic.ScaleWidth = $scale
}

function OpenWordDoc()
{
  $word = new-object -ComObject "word.application"
  $word.Visible = $True
  $doc = $word.documents.Add()
  $doc.PageSetup.TopMargin = $topMargin
  $doc.PageSetup.BottomMargin = $bottomMargin
  $doc.PageSetup.LeftMargin = $leftMargin
  $doc.PageSetup.RightMargin = $rightMargin
  $doc, $word.Selection
}

. Main $args[0]

I solved a similar problem using PS and Word. This simple script opens Word and inserts images into a new doc. Then you can manually save the doc as a PDF or other formats. This can be automated too, but I prefer to leave Word open to inspect it and make minor edits before saving.

This script is useful for getting rid of old magazines. Just scan the pages you want to keep to image files in a single folder, run the script, then save the doc as a PDF for your Kindle.

$letterWidth = 612
$letterHeight = 792
$topMargin = 0
$bottomMargin = 0
$leftMargin = 0
$rightMargin = 0

function Main([string] $dir)
{
  $files = dir $dir
  $doc, $selection = OpenWordDoc

  foreach ($file in $files)
  {
    $par = $doc.Paragraphs.Add()
    $par.SpaceAfter = 0
    $par.Alignment = 1
    $pic = $par.Range.InlineShapes.AddPicture($file.FullName)
    ScaleImage $pic
  }
}

function ScaleImage($pic)
{
  $hScale = ($letterWidth - $leftMargin - $rightMargin) / $pic.Width
  $vScale = ($letterHeight - $topMargin - $bottomMargin) / $pic.Height
  $scale = [Math]::Min($hScale, $vScale) * 100
  $pic.ScaleHeight = $pic.ScaleWidth = $scale
}

function OpenWordDoc()
{
  $word = new-object -ComObject "word.application"
  $word.Visible = $True
  $doc = $word.documents.Add()
  $doc.PageSetup.TopMargin = $topMargin
  $doc.PageSetup.BottomMargin = $bottomMargin
  $doc.PageSetup.LeftMargin = $leftMargin
  $doc.PageSetup.RightMargin = $rightMargin
  $doc, $word.Selection
}

. Main $args[0]
