PDF to TIFF conversion
Hello,
I am extremely impressed with your SDK and is very close to what we need
Our program needs to convert PDF documents into B/W 1Bit, Dithered TIFF images. We currently use Ghostscript but are evaluating your SDK. So far the process has been really smooth but there are a few differences between the results.
Your SDK result is the left image and Ghostscript is on the right. These are highly magnified as our users need to zoom right in to work on detail of floor plans
Ghostscript seems to produce slightly less ragged results when dithering.
I am using a variation of your example DrawPageToIStream
crp.Flags = pxvrpf_Dither | pxvrpf_BlackAndWhite;
crp.RenderTarget = pxvrm_Printing;
dip.ImageFormat = IMGF_TIFF;
dip.Flags = 0; // reserved
dip.Bpp = 1;
hr = PXCV_DrawPageToIStream(curDoc, page_num, &crp, RGB(255, 255, 255) | 0xFF000000, &dip, pImage);
Are there any other settings I can use to match the output with Ghostscript?

Re: PDF to TIFF conversion
Can you provide a source PDF file?
We would like to analyze why that happens and maybe provide some recommendations.

Re: PDF to TIFF conversion
Thanks for the reply.
the atached rar file, contain the original PDF and the TIF created by Ghostscript
Compare this to the tif generated by your SDK.
When you zoom in Ghostscript's has fewer artifacts and looks a bit cleaner.
The differences appear very minor but they will make a difference because of the way we use them
Thanks again
Phil

Re: PDF to TIFF conversion
Looks like we have some issue with stroke adjusting on this file.
We will check why it happens and will definitely fix that asap.

Re: PDF to TIFF conversion
Thanks the reply, that is very encouraging as, apart from this issue, your SDK is perfectly suited for our requirements.
If you need any more examples, I can supply - just let me know
Regards
Phil

Re: PDF to TIFF conversion
Some improvements with stroke adjustment should be available in the new build that should be released next week if everything goes well.
But there still will be some artifacts dithering artifacts, unfortunately. We will continue to work on improvements, but I cannot promise any timeline here.

Hello, oakleaf software ltd
It should have made some improvements, but this will not be a "one-and-done" resolution process, unfortunately. As Ivan said before,
