Need assistance to get webp image into libreoffice impress with impress adding a background to it

[hansonrichardj]

hello,
I insert an image (webp) into impress black image with transparency and it will flip it, transparency is now black and the black image is now transparent.

I thought I was doing something wrong but the image opens in gimp, firefox, exactly like is should.

I also opened the image in Draw and the image is flipped just like impress

I converted the file to png and impress does not change it.

I read that libreoffice was suppose to support webp, but either I misread the info or …

I do not want to convert tons of images to png just to use in impress, so what am I doing wrong?

Thanks

would not allow me to upload webp file, even tried to trick it with “.png” still would not allow it.

Who knows?

Please attach a sample of the webp image, and the Impress sample file, without private information,
and paste the information in Menu/Help/About LibreOffice, there is a copy icon.

I can’t see any difference in Impress, Draw and GIMP. See attached file.
Transparent text in black rectangle.

EDIT
I have to correct myself. I downloaded the following image (colored dice):
URL: WebP-Bildgalerien  |  Google for Developers
Download link: https://www.gstatic.com/webp/gallery3/3_webp_ll.webp
Results:

• Chromium/Chrome/Edge/Firefox: grey background, seems to be sort of transparent (same as png)
• LibreOffice (Impress/Draw/Writer): realistic preview, defectively displayed
• GIMP: well displayed, can compress when exporting
• Xviewer: well displayed

Hello Grantler,
The real issue is, the text is black and the background is actually transparent. When you pull the image from libreoffice it changed it.

I have attached my copies of the original webp in firefox, gimp, image view (Ubuntu), and Inkscape

[Grantler]

You are right: I produced a webp Image and inserted it in Draw: properties changed dramtically!
As stated in my last comment: The import of webp images in LibreOffice is not correct. Only the preview is okay.
