Convert PPTX slides to Images

We are trying your product as trail version to check whether we can convert PPTX slides to best quality images. As far we have try to use it with .Net core and with the package available for .net core there are no method as ChartToImageConverter().

And also, we try this on .net framework with the related package and also, we are getting error on “Creates an instance of ChartToImageConverter”.

1. We would like to know whether there is any possible way to fulfill our requirement using your product on .Net core. If you can provide us an example project that will be a great help.

Thank you!

Hi Harshana, 

Currently, we are implementing the chart support in PPTX to Image/PDF conversion in .NET Core application. This feature implementation will be included in our upcoming main release 2019 Volume 1 which is estimated to be available by March 2019. 

Regarding ChartToImageConverter initialization issue: 
We request to refer Syncfusion.OfficeChartToImageConverter.WPF assemblies and initialize ChartToImageConverter instance for converting chart in PPTX to Image which is explained detailly in the following link.

Thanks you for the information.

And i have try to convert PPTX to Image and PDF using global licensed version.

Then I found these problems which i like to resolve with the best way. Please kindly consider and reply ASAP.

1 ~ When we use custom slide size to our PPTX (Letter paper) and then the content will be overflow in the converted Images and PDF pages.
2 ~ When we have charts in our PPTX after converting, formatting and text alignments of those charts have been changed.

Thank you !

Hi Mariusz,

Thank you for your update.

We regret to let you know that, it’s not possible to change the size of the converted image directly by using Syncfusion Presentation library. Because, by default Presentation library uses a width and height of a PowerPoint slide that used to convert.

However as a workaround, you can achieve your requirement by creating the PowerPoint slides with desired size and then convert to image using Essential Presentation library. Based on this we have prepared the sample and It can be downloaded from the below link.

Please find the attached Core sample to generate the image in 150 x 100 pixel with Presentation library.

Please let us know if you have any other questions.
