How to read a PDF Portfolio using iTextSharp

由 匆匆过客 提交于 2019-12-06 06:31:20

问题 When decoding an image within a PDF as FlateDecode via iTextSharp the image is distorted and I can't seem to figure out why. The recognized bpp is Format1bppIndexed . If I modify the PixelFormat to Format4bppIndexed the image is recognizable to some degree (shrunk, coloring is off but readable) and is duplicated 4 times in a horizontal manner. If I adjust the pixel format to Format8bppIndexed it is also recognizable to some degree and is duplicated 8 times in a horizontal manner. The image

问题 This question was asked previously (iTextSharp 5.5.6.0 Bug? check box tick mark changes) but with no answer supplied, I cannot comment because I am a new user. I am having exactly the same issue.

In build 5.5.5.0 and 5.5.6.0 they are now a cross symbol. Don't think setting the property would have any effect as already set to this in the
