Can NvMedia's 2D really do image scaling?

Autonomous Vehicles DRIVE PX 2 DriveWorks

I refer to the following documents.

(Conntents = Multimedia Programming → NvMedia Image Domain → Image 2D)

---- Excerpt ----
The NvMedia Image 2D component supports image surface processing features such as image copy, image scaling, image cropping. It operates on YUV/RGB input and output surfaces. It also performs format conversion to/from YUV to RGB and supports aggregated image handling.

So,I have read the description about the API of image2D.

(Conntents = API Modules → NvMedia API for Tegra → Image API)
I also checked the links of “Data Structures” and “Modules”.
But I could not find a description about the image scaling and API information

I will ask you 5 questions.
I want an answer as soon as possible. I hope that you will answer even one of them.
However, I would like you to finally answer everything.

Question 1. Can NvMedia’s 2D really do image scaling?
Question 2. If the answer to question 1 is Yes Please tell me which document to read.
Question 3. If the answer to question 1 is No, please tell me where the scaling is done and which document to read.
Question 4. I would like to specify the parameters for scaling and cropping. Is that possible?
Question 5. Are the documents I should read in DevZone and Vibrante SDK?

Notice
I do not have permission to refer bin files and documents yet in DevZone.

Best regards

I am sad that there is no answer.
When can you respond?

For example, it seems that NvMedia2DBlit API is able to scale images…

Thank you.

Dear atsutaka.

Suppose I want to doubles image horizontally and vertically.
Which of the NVMedia 2 DBlit APIs is the relevant API parameter?
Please also answer to question 4.

Best regards.

Dear atsutaka

I have read the following documents.

“If the dimensions of the source rectangle do not match the dimensions of the destination rectangle, pixels are scaled to fit the destination rectangle.”

I understood as follows.
・source rectangle = NvMediaImage * srcSurface,
・destination rectangle = NvMediaImage * dstSurface
Scaling is performed automatically if the above parameters are compared and mismatch.

Therefore I will close this question.
If I am wrong please tell me the correct answer.
Thank you very much for your support.

Best regards
