Reply to "Electronic map file size"

Duane,

I will start sending the certificate to clients every time now, since you recommend it. Some of my clients have a difficult enough time retaining the course map I send them. I am often asked to re-send it. Therefore, I wonder if they will really "have it if they need it". Furthermore, if the race claims "certified course", and there is no record of the course on USATF.org, what more do we need to establish whether or not it has a current certification? This may just be my boneheadedness - but I fail to see what purpose producing a certificate proves when we can simply look it up on line. Again, isn't this one of the reasons for having this site in the first place?

On the file size/conversion question: I merely opened the color PDF in Corel Draw (same process in Illustrator) and exported it as a reduced-pixel PNG. This was a PDF I made from a Word document. I can go into detail on the exact process for anyone who is interested. It is relatively simple.

My boneheadedness again apparently prevents me from understanding something - how a scanned color PDF could be different for the purposes of converting it to a PNG than any other color PDF. I can scan a color document into a PDF of the size I choose, open the PDF in Corel (or Illustrator), then export it as a color PNG of the size I desire. Out of curiosity, I just did this with a random color document from my desk - a Washington Nationals schedule (no one is laughing at the Nats this year - so far, anyway). Here is the 376 Kb result: http://tinyurl.com/cxen3z8 . Color PDF scan thus converted to small PNG.

Lyman - first, you should always send the certificate to your client. If they ever need it, they would already have it. Certification includes the certificate. I have run across a couple races that claim "certified" courses, but they were unable to produce the certificate. They never had one, and that is the point. Always send a cert to the client.

Now, about file size. How was your 980 kb PDF created? Did you scan it? Was it color, or monochrome?

My observation has been that black-and-white PDFs convert to small png files, but PDF files produced from color scans don't convert to small png files. That is what I am trying to discover - if others can take a PDF created from a color scan, and make a small png file from that PDF file.
