pdf file viewing problem in Answers

Hi @krisrodriguez

I uploaded a schematic .pdf file for this answer but when clicking on it to view it, it doesn't show everything. There are a lot of blank pages and pages not completely filled with text, drawing etc.

When the file is downloaded from the document page in ifixit using the download link on the page it opens OK on my PC. showing everything is there.

Interestingly enough it seems to be only the above file as I uploaded this one a bit before the one above and it displays OK when viewed on ifixit.

Answer this question I have this problem too

Is this a good question?

@jayeff, have you tried to upload a different PDF to see if the same thing happens?

by

@jayeff previously I have had similar issues like that. The problem was that the original PDF file was not a true PDF. Can you provide a link to the original file? Might be worthwhile to check the file.

@oldturkey03

This is the link that I downloaded it from

by

@jayeff thank you and I just checked it. Same issues of course and it displays well anywhere else but not as an attachment on iFixit. @krisrodriguez back in your court Czarina :-)

@oldturkey03

Thanks.

Good to know it's not just happening with me ;-)

Cheers

Hi @krisrodriguez

I tried uploading the same file again today in a new question that I created and also another file at the same time as well to see what happens.

The attached image below shows examples of what happens.

The 1st image on the left shows a page from the problem document as seen in a browser when it is opened directly from the file stored in my PC i.e. all is OK, before it was uploaded

The 2nd image from the left is the same page from the same document after it has been uploaded and viewed in the same browser on my PC when it is opened in the ifixit pdf viewer, i.e. missing text etc

The 3rd image from the left shows the same page, when the document has been downloaded from the download link in the same ifixit pdf viewer page where it doesn't fully display and has been saved to my PC so presumably all the uploaded data has been received correctly at your end i.e. the entire document is OK not just the example page

The 4th image from the left is taken from a document file that was uploaded from the same PC just minutes after the problem document was uploaded, just to show that all is OK. (the entire document is OK not just the example page).

I had to test this in ifixit/answers because it seems that when I try to upload pdf documents here i.e. meta/answers there's an S3Exception occurred with error code: 404 message.

This happened every time regardless of which pdf file I try to upload as I tried 2 other ones plus the 2 linked in the "question" linked at the start of this answer.

Hopefully this information will be of some help to find out what's wrong, as I'm not convinced it is at my end.

@jayeff, thank you. I'm going working with the team to see if we can get this fixed up.

@jayeff, The dev team is aware of the issue, but we don’t have a timeline for a fix just yet. It’s a bit of a tricky one, and with other priorities in the queue, we can’t say exactly when it’ll be addressed. That said, it’s on the radar, and we’ll update if anything changes. Thanks again for taking the time to investigate.

您好！根據您的描述，PDF檔案在iFixit頁面上顯示不完整（出現空白頁或內容缺失），但下載後在本地電腦上開啟卻正常。這種情況可能與以下原因有關：

  1. 1. 瀏覽器的PDF檢視器問題

- iFixit可能使用瀏覽器內置的PDF檢視器來預覽檔案，某些瀏覽器（如Chrome、Edge）的內置PDF檢視器可能無法正確渲染複雜的PDF檔案。

- 解決方法：嘗試使用其他瀏覽器（如Firefox）或在瀏覽器中安裝專門的PDF外掛程式（如Adobe Acrobat Reader的外掛程式）。

  1. 2. PDF檔案本身的兼容性問題

- 如果PDF檔案使用了特殊的字體、圖像壓縮格式或高級功能（如圖層），可能會導致某些檢視器無法正確顯示。

- 解決方法：嘗試將PDF檔案重新保存為標準的PDF格式（如PDF/A），或使用Adobe Acrobat等專業工具優化檔案。

  1. 3. 伺服器端預覽問題

- iFixit的伺服器可能在生成PDF預覽時出現了問題，導致部分內容丟失或顯示不完整。

- 解決方法：聯繫iFixit的技術支持團隊，提供檔案並說明問題，他們可能會修復伺服器端的預覽功能。

  1. 4. 檔案上傳不完整

- 如果在上傳過程中網路不穩定，可能會導致檔案上傳不完整。

- 解決方法：重新上傳檔案，確保上傳完成後檢查檔案大小是否與原始檔案一致。

  1. 5. 快取問題

- 瀏覽器或iFixit的快取可能導致舊版本的檔案被顯示。

- 解決方法：清除瀏覽器快取，或嘗試在無痕模式下檢視檔案。

  1. 建議的操作步驟：

1. 嘗試使用其他瀏覽器檢視檔案。

2. 將PDF檔案重新保存並上傳。

3. 聯繫iFixit支持團隊，提供檔案並說明問題。

希望這些建議能幫助您解決問題！如果問題仍然存在，請隨時提供更多細節，我會進一步協助您。

English:

Hello! According to your description, the PDF file is incomplete on the iFixit page (blank pages or missing content), but it is normal to open on the local computer after downloading. This situation may be related to the following reasons:

1. Browser's PDF viewer problem

- iFixit may use the built-in PDF viewer of the browser to preview files, and the built-in PDF viewer of some browsers (such as Chrome and Edge) may not be able to render complex PDF files correctly.

- Solution: Try to use other browsers (such as Firefox) or install special PDF plug-ins (such as Adobe Acrobat Reader plug-ins) in the browser.

2. The compatibility problem of the PDF file itself

- If the PDF file uses special fonts, image compression formats or advanced functions (such as layers), some viewers may not be displayed correctly.

- Solution: Try to re-save the PDF file as a standard PDF format (such as PDF/A), or use professional tools such as Adobe Acrobat to optimize the file.

3. Server-side preview problem

- The server of iFixit may have problems in generating PDF previews, resulting in the loss of some content or incomplete display.

- Solution: Tach the technical support team of iFixit, provide the file and explain the problem. They may fix the preview function on the server side.

4. The file upload is incomplete.

- If the network is unstable during the upload process, it may lead to incomplete file upload.

- Solution: Re-upload the file and make sure that the file size is consistent with the original file after the upload is completed.

5. Cache problem

- The cache of the browser or iFixit may cause the old version of the file to be displayed.

- Solution: Clear the browser cache, or try to view the file in traceless mode.

Suggested operation steps:

1. Try to use other browsers to view the file.

2. Re-save and upload the PDF file.

3. Fixit support team to provide documents and explain the problem.

I hope these suggestions can help you solve the problem! If the problem persists, please feel free to provide more details, and I will further assist you.
