Can a bunch of you open up any of my postings in the 'special projects' section and tell me if the photos imbedded in the pdf's show up as normal photos or just fully black areas?
All I can see when I do that are black areas, the text is ok.
This phenomena has been occasional but now seems permanent to me no matter what internet device I use to view the web site, crazy.
Cheers, Fred.

Works here. You might need to reinstall something.

They show in colour for me. Maybe a memory size problem?

BTW: You might like to edit your television project thread titles to use the word inch as this forum's software apparently has a problem with the double quote character and converts it into single quote, making yours 3 and 5 foot screens.

Hi GTC, I'll watch that ' / " thing, I ignored it as a glitch before but will use the text from now on. If only it was that easy to expand the actual CRT size!

The black photos seem to be at my end on translating the imbedded pdf back.
If I send the pdf by email as an attachment to myself the photos are normal.
I have not changed anything at this end so its a mystery.
At least you guys seem to seeing the pix ok so that's the main thing.
Fred.

A thread's creator can edit an existing thread title.

Are you using Acrobat to view your files? There is some discussion on the web about various non-Adobe PDF viewers having problems with colour rendering.

There's also the issue of which type of PDF viewer is launched by web browsers when they open a PDF file.

Hi GTC and all, I have no problem viewing any PDF file with any of my computers using acrobat , or any other viewer outside of this site.
The only problem I have is when I click on the link within the post to view the linked file. the problem is something to do with the passage through the site.

I don't understand the mechanism in viewing a linked file on this site as I have no choice ( I think) about what piece of magic does that for you!

I'm lost at the moment, I have sent PDF's to destinations for years and never had this weird problem although this is the first time I have had a lot of linked pdf's on one web site.

I commonly use Nuance PDF Converter Pro8 to view, edit and pack pdf's and have for a couple of years sending files and manuscripts to magazines and so on.

I suppose I should ask the question 'does ANYBODY EVER see a black rectangle instead of a photo in any of MY linked documents on this site?'

Does anybody else send PDF's to Brad with articles or am I the first up and creating a new problem?

Fred.

I should add I can view PDF's created by adobe, pdf creator , pdf 956(I think) with nuance, adobe ect ect with no problem.

The black rectangles happen to me randomly and even when I view the files directly from Outlook.

if you are using Windows 7 I'd recommend Win2PDF (US$20.00 I think) and if Windows 10, I'd recommend using the standard PDF creator in Windows to print PDF documents. If there's still a case of black rectangles then we need to look elsewhere for the issue.

We do have a lot of PDF documents here, most are from MonochromeTV though most of these are circuit diagrams.

Hi Fred

Another option for creating PDFs that always gives good quality, compatible results and is COMPLETELY FREE is the built-in Save as PDF feature in Open Office. It will open your Word files.

I no longer use MS Office for creating manuals etc.. Open Office just works better and doesn't crash like MS Office does.
The Drawing functions, particularly the polyline functions, are miles ahead of MS Office once you take the time to learn them.

I no longer make hand-drawn sketches!!

And you don't have to pay for it every 12 months!!

Ok guys thanks for that I have some W10 machines so i'll create the PDF's in that from now on.

I do my writing on a stand alone ( no internet) XP pro pc as it has many apps in it to do with photo/audio/video manipulation from the 2000's.
I then transfer to a W10 network or my W10 laptop mobile to work the internet. Editors like plain text and jpgs for publishing
.
Sounds like I better start using W10 and word for this internet stuff.

As no one else has a huge problem it definitely is at my end.

Cheers, Fred.

I have varied my routine for the second part of the story of the 3 inch TV set.

Having already created this in Word 2000.
I have walked the doc over to a network pc and saved the doc on a W10 pc in word, then converted to a PDF using Adobe on this W10 pc.
I'm now posting this on that same pc and will swap to Mail to email that pdf to Brad.
I'll post some dialogue on the thread in 'special projects' for Brad to pop the link in.
Fred.

There is also the option if you are not sure, to instead of "phone a friend" find one to email it too.

I always found, in earlier times, that anything you could do in Word you could do faster in WordPerfect with a fraction of the resources.

I actually do two different Newsletters, so in one in particular photos go in en mass. After that has all happened, it is eventually saved as a pdf. I do have a program that converts pdf, but it has its moments.

Naturally any photo's are cropped & adjusted in one of the image editors, before hand.

You may have some form of file corruption. It does pay to run Malwarebytes through the system as some over promoted older & were good ones, are now clunky & miss things. Computers can load up a huge number of temporary files and that can eventually cause problems. Their capacity is not infinite.

Do go to the "properties" of the "C" drive & do a regular disk clean up & disk check. Most uninstall programs are clunky & inefficient & I have on numerous occasions needed to manually removed them from "programs" & the "registry" (back it up before going there).

If Adobe is playing up be very cautious of where it came from, as you may get more than it. Several times Kaspersky or Malwarebytes here (both registered copies... that way you get all of the features) have blocked dodgy sites.

Remove any Adobe: Diskclean & reinstall a clean copy.

Marc

Hi all, the problem was never in my PDFs as such as they were always veiwable EXCEPT when browsing into the site and clicking on the link.
This morning I swapped browser to google chrome from MS edge (whatever that is)and the pics show up fine in every article.
Why? I dont have a clue, I get black blacks using edge and colour pics using google.

So i'll use google as my default browser!
Problem solved.
Next problem!

Thanks everybody for the ideas.
Computers...................grrrrrrrrrr.

Fred.

My default browser is Firefox and sometimes, Vintage Radio & Television and elsewhere, it won't open pdfs. Chrome usually works but if it doesn't microsoft edge does. My system is W10 on a Dell laptop.

Recently I emailed a pdf to one of my relatives and it would not open. This pdf was produced on my old desktop clunker running XP pro. The software was from a magazine disk from many years ago, and is discrete software, that does not work through the print dialog box. Hope that that there are not too many of these legacy problems as a lot of my finalised document files for family and genealogy were converted to pdf, particularly a WW1 diary of my paternal grandfather. This is a huge file consisting of scans of each handwritten page, with text on the opposite page, and with extracts from the regimental diary and other sources. This has gone to relatives and maybe it will stop working - but have kept the word file so should be recoverable.

Looks like for important docs it is essential to keep them in different formats.

It's interesting to see what is working for some isn't working for others - fairly typical of modern problems.

I overlooked the web browsers which isn't like me though I am using Edge and have found that the revised file is now working though the second file isn't.

I'll take the unusual step of linking to them here so we are all on the same wavelength and don't need to jump between threads.

3 inch TV - The Design
3 inch TV - CRT Test

Let's call them File 1 and File 2 for clarity.

File 2 has been left as is at this stage. File 1 was sent to me as a raw Word file, which I printed to PDF in Win2PDF and then uploaded to replace the original. File 1 now displays the photos but File 2 doesn't.

Update: I just tested in Internet Explorer and the same thing happens. The rendering engines are technically different despite being related software - Edge is better as displaying modern HTML5 websites than IE does. Although a PDF file is a different issue altogether.

Update: I do have other browsers installed for development purposes and just tried Chrome. It is not as picky as IE and Edge appear to be and does display both PDF files with the photos.

Update: I've just tried in Opera and it displays both files with the photos intact.

Update: I've just tried in Firefox and, like Edge, it only shows the photos in File 1.

Update: I just opened both files using Apple's Safari browser but it doesn't appear to have its own PDF reader built in and defaults to Edge, which then behaves the way it does when used on its own. That said, I doubt that Safari is used much on Windows computers so the result would not affect many people.

I think in the interim, it will be best for those who have experienced problems with PDF files they have previously sent, to send me the material in Word format and I will do the conversion before uploading.

I don't watch PDFs in-browser, instead clicking the link just downloads the file. I then open them in Windows Explorer by double-clicking, and they open in Adobe Acrobat Reader version 2017.009.20044 . All the files, before and after, display perfectly fine.
