SVG graphics / PNG files blurred

[mfeske]

Hello everybody,
dompdf works really great. However, I have a problem with the integration of graphics. PNG files are very blurred. Is there a way to integrate SVG graphics?

We would be interested in helping figure out the blurry PNG issue. Some of it may be do to extra processing done with the file in 0.6.x. I believe 0.5.x may have inserted the file without modification. It may also be a display issue (whereas print may be fine). Do you have a sample image and a PDF showing the blurry output?

In the meantime there is some SVG support in the upcoming 0.7.0 release. The first beta does not include it, but the second (and hopefully last) beta will. Check out the develop branch. And watch issue #320 for more info (which I see you are already doing).

Hello bsweeney, Thanks for the note. Where do I know the version of the dompdf? I think I had the loaded from the Google Code, as there was with the from the git problems. So far, almost everything has indeed worked. Except for the problem with the image. Can I send you the PDF file by e-mail? How can I now work with the dev git, I put it in a separate path and thought I could now my scripts from / dompdf / on / dompdfgit / change, but that seems to not function.
Another problem which determines not come from dompdf is perhaps also solved with the beta version. When we send the PDF file by e-mail to the fax server breaks the signature. If we will transfer correctly you consign with Hylafax client to the server. Do you have any idea about this?
greeting
Micha and Thanks for your good work!

I responded in issue #320 about getting a version with SVG support.

If you don't have anywhere you can share the file I can set up a one-time upload. Go to http://eclecticgeek.com/dompdf/upload/ and use the password ******* to upload your file (PDF, or ZIP if sending multiple files).

I'm not sure about the signature. Maybe the newer release will behave better with your fax client. Some issues with the PDF structure have been fixed over time.

Hello bsweeney, thanks for the support. I've uploaded the file. There have been used four unterscheidliche fonts. But it is just a script and still looks at the a letter of clearance in the Address and in the footer different from the others. In all four files have the same image file that looks a bit strange to me. I also have an SVG version, but do not know how I einbinde this correctly. The current version level of dompdf allows nocht probably not. As I see the dompdf version.

Hello bsweeney, could you at the png file notice something, why this is so blurred? Has anyone any idea how I can perform the update without my existing settings to overwrite? I need the SVG support and improve the PDF structure so that I can pass the PDF documents neatly on the fax client.

@manish-dev-28 can you share one of the images as well as the HTML used to reference it? Might also help to know what version of GD you're using.

Are you having trouble reproducing this @bsweeney, or it just not a high prio? This has impacted me for the longest time, even with older versions of dompdf.

GD Support => enabled
GD headers Version => 2.2.3
GD library Version => 2.2.3

Here's input image:

When modified by dompdf, it becomes like this:

Looks sharp until you zoom in a bit, and then it becomes very obviously wrong:

@MikeLund it's mostly a matter of finding the time to work on the issue. I suspect it's the extra processing some images types go through. If you switch to a JPG file do you have the same result.
