JvImagesViewer - WEBP
« on: December 20, 2020, 06:41:42 am »
Hi All,

can a TJvImagesViewer be made to display WEBP images?

If so how?

Thanks in advance.

In principle, yes. JvImagesViewer can display all image formats registered. You must provide and register a corresponding image class plus a reader for the WEBP format. Study the code of TJpegImage or TPortableNetworkGraphic.

Here is the implementation of the reader in BGRABitmap:

You can probably adapt it to run without BGRABitmap.
