I used TCPDF in Laravel project for output pdf that was couple weeks ago. It worked perfect. I copy the project folder for backup. Today I tried to output pdf. Error 503 shows up. so I used backup data but it also problem browser ask me to open pdf or save pdf, when I open it it's all white blank pdf page. I'm guessing Is it my CDN problem?
I need pdf output function. Could you teach me what is cause please? and also if you have recommendation. I would like to know other PDF output library.

I was hoping someone could shine some light on a strange issue I have stumbled across recently within my Laravel CRM application. I am using MultiCRM + Laravel BAP to operate a small CRM system on my server.
The issue I am experiencing is that when I upload "specific" PDF documents through the CRM's AJAX file uploader, the file uploads and reaches the 100% stage and thereafter the following error is being returned:
Unprocessable Entity
I have reviewed the error status/message within the Network tab of my Developer Console and I am seeing the following error:
The given data was invalid - The files must be a type of Jpg, jpeg,
png, pdf, txt, doc, docx
Some PDF's I can upload perfectly fine whereas other PDF's seem to be failing. I have checked the Properties of the file which I am attempting to upload and I can confirm that the file extension resembles the exact same of the PDF files which are uploading perfectly fine.
I have also reviewed the max_upload_size and post_max_size within my php.ini and I can confirm the values set in there are fine. I have tried to upload larger zip files 20mb+ to rule out any file upload size limits, and I can confirm that the zip files in question uploaded and saved perfectly fine.
I am just a little confused with why certain PDF files will upload and others won't.
If there any particular files which you should need to see, please let me know and i would be happy to provide the source code :-)
This is driving me crazy. I have a jupyter notebook with images and I'm trying to convert it to a pdf on my mac. I've installed pandoc and macTex, but when I try to convert it to pdf the images disappear. Also the formatting for my tables gets messed up. I've tried saving it as a markdown and converting it, but I get the same problem. If I convert to html the images disappear but the table formatting is correct. I've also tried converting it in the terminal with nbconvert, but the images still disappeared. And I tried converting the markdown file with rstudio, but still the images disappeared. I've tried two versions of the code to reference images. The versions are below, both display fine in the jupyter notebook but the first one throws an error and the second one the images disappear. I've googled around, it seems to be a common issue but I'm not seeing a lot of solutions. I really can't believe this is this difficult. Any solution is greatly appreciated.
code with errors:
code disappears when rendered:
<img src="Stars_Boxplot.PNG">
Update Solution:
The issue was it had to be an absolute reference and I had a space in my file path.
We have encountered multiple corrupted Instagram Standard Images (612px).
This happens the last 3-4 days. And across multiple Instagram users.
Strangely this issue is only evident when the images are opened using Adobe Photoshop.
When viewed using Mac's finder or Preview this image corrupt problem is not visible.
It affects about 50% of our customers. And mostly about 10-20% of their choosen images. And some can affect around 50-100% of their images.
Example of corrupted images:
http://distilleryimage10.s3.amazonaws.com/5875aa2eb24411e3bfe2124c49cf34ce_8.jpg
http://distilleryimage0.s3.amazonaws.com/3b3452a8b24411e3b352126f9f588c64_8.jpg
Again, this issue is only evident when the photos are being prepared to print.
Or when it is opened using Adobe Photoshop/Acrobat/Illustrator/Indesign.
Please help.
Thanks

I managed to solve my issue with the same description. What I first did was download the images to my webserver exactly to what is was online, so I didn't change anything of the file contents, just get en then put in the file.
How I solved my problem? I use PHP to generate the image now after I donwloaded it the same way. This is the simplified version of my script:
<?php
// Create an image instance
$im = imagecreatefromjpeg('instagram_image.jpeg');
// Disable interlacing
imageinterlace($im, false); // did not use this but will do the same
// Save the image
imagejpeg($im, 'instagram_image.jpeg');
imagedestroy($im);
?>
When I started using this simple create and save script it all worked again. It looks like it does nothing but it did a lot for me! Hope it helps someone saving a lot of time, took me 1,5 day to figure out the exact problem.
I have a site - www.jcrocetta.com.
On this site I have 2 pdf files. One file has blurred data and the other is clear, both files were created with pdftk.
In order to blur out some personal data in the pdf I used Inkscape. But Inkscape only opens/edits one PDF page at a time. After I made my edits in Inkscape I saved the files as .pdf formatted files. At that point I had three separate pdf files, pages 1 through 3. I then used pdftk to concatenate the 3 files into one.
The final pdftk-produced files are on www.jcrocetta.com. Just click the public information button.
In Chrome viewing inline works fine.
Downloading the file from Firefox works fine too.
But viewing inline on Firefox it renders blank pages. How can I fix this?
Also, I know that pdf files not produced with pdftk will render correctly on both Chrome and Firefox.
Thanks for your help.
FireFox has a lovely new feature: It now uses the PDF.js library to render PDF files, instead of calling out to an Adobe Reader plugin, or forcing you to save the file to disk. Unfortunately, it seem that PDF.js isn't quite perfect yet. A quick search shows that other people have the same issue, but the only "solution" I've seen offered boils down to "file a bug report at https://github.com/mozilla/pdf.js/issues or https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=PDF+Viewer".
Also: Do the three individual PDF files render in FireFox, before you use pdftk to concatenate them?
I am using fckEditor as text editor. When i upload images thru it the images were uploaded to app/webroot/fckeditor/images.
And when they're embedded it looks like
/fckfiles/SalmonSashimi.jpg
Until now it looks right.
But the image doesn't appear.
So when I browse the image directly, at here
http://www.in-culture.info/fckfiles/SalmonSashimi.jpg
instead of displaying the URL, Cake interrupts the image call and trying to render it in a layout. I often face this error when I point .html file for iframe scroller and .xml file for flash embedding. This is really embarrassing
You can see the page here
http://www.in-culture.info/events/view/42
That image should appear before the text - "More" dont appear for short text.
Thanks for you help.
Try to change the path where the images are saved. Instead of
/app/webroot/fckeditor/images
try to change to
/app/webroot/img/fckeditor/
I believe that it's possible.
It's resolved now.
It was not cake's fault.
I pointed incomplete absolute path at FckEditor so it didn't upload the files well.
However the uploader mistakenly passes the "OK" so the HTML tries to display it.
So cake tries to render something, as usual, when there is no physical file.
I spent about 10 hours to resolve this.
Now I don't hate cake as I did a few hours ago. (: :)
