What is the Best Image Format to Store in a PDF file

[qcrnd]

Hi
I Create a PDF file and I import TChart images into the PDF file e.g.

Steema.TeeChart.Export.JPEGFormat img = tChart1.Export.Image.JPEG;
img.Save(stream)
Bitmap bmp = new Bitmap(stream)

And I add the bmp to my PDF.

I found that the images dont look so nice inside the PDF , A little blurred
I tried JPEG , Bitmap TIFF.
What do you recommend to get the best results for a chart to be inserted into a PDF file.

I saw that PDFFormat creates very good PDF image files but I dont know how to use it in my code since my PDF SW knows how to add System.Drawing.Image objects.
How can use the Data in PDFFormat , the stream or anything else to make it a System.Drawing.Image. I get an exception when I try

System.Drawing.Image image = System.Drawing.Image.FromStream(stream); ?? EXCEPTION !!!!???

What exactly is the PDFFormat.

Thanks.

Thanks.

Hi qcrnd,

PDFFormat generates a PDF file. You could try saving it to disk and openning it with notepad and with a PDF reader. You'll see exactly what it contains.
