Aspose Cloud December Pricing Update

Simplifying Pricing for New Customers

We have updated the Aspose Cloud pricing structure to simplify it for new customers. Previously some API calls were “chargeable” while other API calls were not. If an API call created a document or meaningful result, then it was chargeable. If an API call did not create a document or result, then it was not chargeable. However, there were some ‘grey areas’ with certain Aspose Cloud products where customers were confused about whether they should be charged for some calls.

To resolve this issue we have updated our pricing to now charge for every API call made, regardless of what the API call does. At the same time, the cost of each API call on the new pricing scheme has been reduced by 1/3.

How does this affect Existing Customers?

Since the effect of this change is different for every customer we have not automatically switched existing customers to the new pricing. Instead as with every pricing change we have “grandfathered” existing customers who will continue to be charged based on the pricing when they signed up.

If you are an existing customer who wishes to switch to the new pricing, you can do this by visiting the “Buy Now” page within your Aspose Cloud account.

You can find more information on the new pricing here:

Aspose.Storage Cloud has been Discontinued

Aspose Storage Cloud

Aspose is glad to share with you that Aspose.Storage Cloud API features are now more simplified. Files and folders storage and their manipulation are no more dependent on the separate Aspose.Storage Cloud API, however, these features have been integrated within every Aspose Cloud API. To be very precise, “Aspose.Storage Cloud has been discontinued as a separate product”.

What existing users can do?

Aspose.Storage Cloud API and following SDKs will remain available on the public repositories like GitHub, NuGet, etc for the existing customers until 31.12.2020:

  • Aspose.Storage Cloud SDK for .NET
  • Aspose.Storage Cloud SDK for Java
  • Aspose.Storage Cloud SDK for PHP
  • Aspose.Storage Cloud SDK for Python
  • Aspose.Storage Cloud SDK for Ruby

Therefore, we recommend updating your applications to the latest versions of SDKs / Endpoints as soon as possible.

Aspose.Storage Cloud will neither be available for purchase separately nor as a part of Aspose.Total Cloud Product Family any more. However, the technical support welcomes you for any further queries about the migration to the latest versions.

How to work with new APIs?

The below sample shows how you were using Aspose.Storage Cloud API to upload the file to Cloud Storage:

// cURL example to upload file to Cloud Storage
curl -v "" \
-X PUT \
-T sample.docx \
-H "Content-Type: multipart/form-data" \
-H "Accept: application/json" \
-H "Authorization: Bearer <jwt token>"

Now you can achieve this using any of the Aspose Cloud APIs. Below sample shows Aspose.Words Cloud API to upload the file to Cloud Storage:

// cURL example to upload file to Cloud Storage
curl -v "" \
-X PUT \
-T sample.docx \
-H "Content-Type: multipart/form-data" \
-H "Accept: application/json" \
-H "Authorization: Bearer <jwt token>"

The most notable change is the Base URL of the API.

With the introduction of new property now you can specify to show data labels over the maximum of the chart in that case.

For example, in following chart maximum value of the vertical axis is 6 but Column 04 in Category 2 has value 7, so the data label is not reflected in this case.

Now starting from this release, you can control the Data Labels appearance in discussing scenario. You can set ShowDataLablesOverMaximum to true and get the data labels in the chart:

A cURL example to update the Chart properties:

How to Add Checkbox Field in PDF?

While working with PDF forms, you need to create checkboxes for data collection when there are lists of options and the user may select any number of choices, including zero, one, or several. In other words, each checkbox is independent of all other checkboxes in the list, so checking one box doesn’t uncheck the others. In this release, Aspose.PDF Cloud introduced support of checkbox field. Now you can add, update and get checkbox from PDF document or specific page or by checkbox field name.

Follow these steps to add a pre-selected checkbox field in a PDF document:

How to Add Radio Button Field in PDF?

A radio button is a very common control used in the forms. These are used when there is a list of two or more options that are mutually exclusive and the user must select exactly one choice. In other words, clicking a non-selected radio button will deselect whatever other button was previously selected in the list. Now you can add, update, and get radio buttons from PDF document or specific page or by radio button field name.

Here we demonstrate how to add a radio button into a PDF document using C#:

Repeat 1-3 steps from above example if required and use following code snippet to add radio button option in PDF document.
