Quality Problem after conversion PDF/A to Image

Hello guys,

if i am converting a black/white  PDF/A to Tiff#s i am getting a problem with the quality of the image. Is there a way to get a better quality?

Alex,
I have tested using the latest LEADTOOLS  v19  setup with the following code and I got the attached results:
====================
string filepath = @"E:\PDF150.pdf";
RasterCodecs codecs = new RasterCodecs();
RasterImage img = codecs.Load(filepath,0,CodecsLoadByteOrder.BgrOrGray,1,5);
codecs.Save(img, @"E:\Converted_To_TIFF.tif", RasterImageFormat.TifLzw, 8);
====================

If you use the same code, do you see the issue? If yes, which version of LEADTOOLS are you using? What is the "File version" (Right-click->Properties-> Details tab) of Leadtools.dll that you have?

Hello Daoud,

string loadfile= @"E:\PDF150.pdf";
string outfiles= @"E:\newTEST\{0}.tiff";

RasterCodecs codecs = new RasterCodecs();
RasterImage img = codecs.Load(loadfile,0,CodecsLoadByteOrder.BgrOrGray,1,5);


CodecsImageInfo imgInfo = codecs.GetInformation(loadfile, true);
int count = imgInfo.TotalPages;
for (int i = 1; i <= count; i++)
{
             codecs.Save(image, string.Format(outfiles, i), RasterImageFormat.TifLzw, 1, i, i, i, CodecsSavePageMode.Append);
}


i am creating for each page in the pdf/a a tiff file. No multipage tiff. the versions i use is 14.5 and 16.5 but if it does work in 14.5 it is better for us. Because this version is in our software.
The quality isn't really better if you look at 3.tiff.

Alex,

I have specified the loading DPI of the PDF and got the attached image which has better quality than yours.

Before calling codecs.Load() add the following lines:

codecs.Options.Pdf.Load.XResolution = 450;

codecs.Options.Pdf.Load.YResolution = 450;

Ok thank you it's now working good
