iTextSharp: 图片 转 PDF 问题...

[iwlk]

bmp 图片: 报错
--------------------
file:///e:/1.bmp is not a recognized imageformat.

png 图片: 报错
--------------------
file:///e:/1.png Colortype 6 is not suported.


我测试着只有jpg图才好使.. 问题是转为jpg后,图片已失真...


问题: 用没有办法让图片不失真转为pdf? 是不是pdf不支持真彩色的图片?

iTextSharp应该不支持bmp,png格式图片
protected void ImageToPdf(string ImagePath,string ImagePath2,string[] Images,string ResultPdf)
{
System.Drawing.Bitmap image;
float height = 0, width = 0;
for (int n = 0; n < Images.Length; n++)
{
image = new Bitmap(ImagePath + Images[n]);
height = image.Height;
width = image.Width;
if (width > height)
{
image.RotateFlip(RotateFlipType.Rotate90FlipXY);
}
image.Save(ImagePath2 + Images[n],System.Drawing.Imaging.ImageFormat.Jpeg);
}
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream(ResultPdf,FileMode.OpenOrCreate, FileAccess.Write));
document.Open();
iTextSharp.text.Image jpeg;
for (int n = 0; n < Images.Length; n++)
{
jpeg = iTextSharp.text.Image.GetInstance(ImagePath2 + Images[n]);
jpeg.ScaleAbsolute(document.PageSize.Width, document.PageSize.Height);
document.NewPage ();
document.Add(jpeg);
}

document.Close();
MessageBox.Show("导出成功！");
}
