getThumbnail: Data from date and time field missing

Aspose.Slides Product Family

Hi,

I have a question about Aspose Slides. I want to create thumbnails of each slide of my ppt-presentation, but the data from date and time field in the footer is missing in every png-file.
I am using Slides 7.5.1 for Java.

Many thanks

Many Thanks,

Hi Mudassir,

the zip-file is attached below. By converting to pdf format the footer is missing, too.

Many thanks

Hi Mudassir,

do you know a workaround about this issue (changing the footer at the master or something like that)?


Many thanks,

Hi Mudassir Fayyaz,

as requested i’ll ask all states of the open bugs in their corresponding threads.
We need the getThumbnail functionallity for our software, which means this bug is a “blocker” for us. I would like to know what is the current state of it?
What is the release roadmap for aspose.slides and when will there be a fixed version available for us?

kind regards,
D.Croe

Hi D Core,

I have verified the issue using Aspose.Slides for Java 8.4.0 and have observed issue to be resolved. For your kind reference, I have attached the generated thumbnail as well. Please try using the suggested version and share with us if there is any issue incurring on your end.

Many Thanks,

Hi,
we’ve tried the 8.4.0 version, but without success. Please attach the ppt file you have used for creating the thumbnail. It looks like there is a difference between ppt files created by an old powerpoint release and ppt files created by a new version and saved under 97/ppt format.
I’ve attached the unmodified ppt file which still has the disappering field.

many thanks,
D.Croe

Hi D.Croe,


I have used following sample code on my end using Aspose.Slides for Java 8.5.0 on my end with JDK 1.6_45. I have not been able to observe the issue specified for footer text in Windows 7. For your kind reference the generated output is also attached. Can you please provide the operating system and Java details on your end as well.

public static void genPPTThumbs(String presName,String path ) throws Exception
{
// String path=“D:\Aspose Data\”;
Presentation pres = new Presentation(path+presName);


for(int i=1;i<=pres.getSlides().getLastSlidePosition();i++)
{
Slide sld = pres.getSlideByPosition(i);
try{ BufferedImage image = sld.getThumbnail(2.0f, 2.0f);
ImageIO.write(image,“png”, new File(path+“Slides/”+presName+"_PPT_thumbnail" + i + “.png”));
}
catch(Exception e)
{
System.out.println("Exception on slide: "+Integer.toString(i));
// e.printStackTrace();
}
}
}

Many Thanks,

Hi Mudassir,

i'm a bit confused, two days ago you wrote about 8.4.0 and today ist 8.5.0. What is the latest version and where do i find release notes? what is the release interval, when will 8.6.0 be available?

right now i will verify the 8.5.0 version ...

we use Java(TM) SE Runtime Environment (build 1.7.0_51-b13), windows7

please attach the ppt file...

best regards,

D.Croe

Hi D.Core,


I am sorry for inconvenience. I like to share that Aspose.Slides for Java 8.5.0 is latest version to date. You can please download that from this link. I am afraid the information may not be available in release notes. Since, issue was logged a year back so when you asked for feedback, I checked that with latest version Aspose.Slides for Java 8.5.0 and found it resolved. Can you please share which PPT file you have requested. I have used the same PPT files that you have shared with us.

Many Thanks,

Hi Mudassir,

the bug is still there in 8.5.0. For me it looks like aspose has a problem with old ppt files. In case i open the file in PowerPoint2007 and save again as PowerPoint 97/2003-ppt the file size increases and after that the datetime field doesn't disapear anymore. But since we have hundreds of old presentations this is not an acceptable option for us. Is it possible that you have opened/saved your downloaded ppt file somehow before the test?

what are the next steps to solve this problem?

best regards,

D.Croe

Hi D.Croe,

Thanks for your feedback. Actually, I have verified the two presentation files shared by you so far and tried generating the thumbnail. The footer text is appearing in thumbnails. Also, in the presentation files shared I can’t see the date and slide number fields visible as well and for this reason they are not shown in thumbnail as well. The thumbnails generated on my end with the presentation files shared by you are identical with presentations. I request you to please share the presentation with which you are able to reproduce the issue along with generated thumbnails. I will test that again on my end to help you further.

Many Thanks,

Hi Mudassir,

please verify that you use the Test.ppt from this thread:

<a href="</a></p><p>the filesize has to be: 17KB! </p><p>If you open it in PowerPoint there should be the dateTime field visible on the second slide in the left corner stating "Here is an Example". this is the dateTime field and not the footer. This thread concerns the date-time field and not the footer (so far i understood, the "footer" is the text in the center?).

let me now if there is a difference on your side in any of the above pre-conditions.

Thanks a lot,

D.Croe

Hi D.Croe,


I am sorry for your inconvenience. I agree with you point that “Here is an Example” text box is placed on a place where usually date time field is visible. Please note that when I open your both presentations (one shared on 06-04-2014 and other recently on 07-25-2013) even in PowerPoint 2010, the date time is not visible at all. Please observe the attached Slide In PowerPoint 2010.png for your kind reference in this regard. The image show the view of presentation being opened in PowerPoint. I have also shared the image highlighting the PowerPoint version as well. Now, please compare the slide Slide In PowerPoint 2010.png with generated thumbnails for the presentations. They are identical and there is no difference between the snapshot and thumbnail generated from Aspose.Slides. Whatever, is visible in PowerPoint is same as generated thumbnail. You may please compare the images for your kind reference. I have also attached the thumbnail images for both presentation files that you have shared with us in this thread so far according to date of sharing.

I hope this will clarify the concept. Please feel free to share if there is any issue incurring.

Many Thanks,

Hi Mudassir,

thanks a lot!

i've tested the behaviour in a more complex environment. Now i've decided to create a testcase with exact the code from the forum and i can confirm this bug has been fixed. Thus our problem is probably caused by another bug!?

I'll try to strip down the "complex environment" to a simple testcase and upload it here as soon as possible.

best regards,

D.Croe
