I would like to know the image data file. is it png raw or raw binary?
Your question is a little vague. Haiku understands png files, yes. But maybe you mean if exporting to png from some application is possible ? In that case, which application do you have in mind ?
If you’re referring to the icon format, no. The icon format is a vector image format called HVIF (Haiku Vector Icon Format). It’s designed to be smaller than SVG while maintaining the scaling properties and fine detail.
Screenshots are typically PNG though.
I can’t think of any other image formats you could be referring to in the operating system.

how could you convert it to hvif
You could try with Icon-o-matic. It has received a lot of improvements recently.
But some ( many ? ) parts of the picture will need to be redrawn in Icon-o-matic.
The 2-step method may be better. Use Inkscape to convert from PNG bitmap into SVG vector image. From there convert to HVIF by loading the SVG into Icon-o-Matic. That way, the source can be edited as a vector image before the new and lightly tested code of the improved Icon-o-Matic is as heavily relied upon.
Image files in Haiku can be of any type. We do not use file endings, but instead have the mime-type as metadata on the file. The mime-type specifies the type of image like png, gif, jpeg or so.
We use plugins to decode and encode image files, which we call translators. So to support a new image format all you need is to have a translator that understands that image format.
