Copy & Paste with transparent background

[handrawn]

I have to agree with acorn - this as far as I can see is an issue with the XDA that does not happen with [some] other apps, so the question still is, why ?

It appears to import two different image files. Copy & Paste from FF imports a 32bit image with an alpha channel. Copy & Paste from Edge or Chrome imports a 24bit image without an alpha channel.

so the browsers render the website differently

but it does not explain:

I can open the original https://www.techhunt.co.in/wp-conten.../Imoji-Wow.png in any browser, Copy image and Paste into MS Word.
I can then Copy from MS Word and Paste into my XDA. Staging like this keeps the Alpha channel and it is transparent on the XDA design page.

I have even dug out Safari and IE and tried.

Works into the older XPAs from a Safari Copy image.
Fails with IE & older XDAs' Preview.

It may be my XDAs all are x64(-bit) and have Paste Bitmaps with Alpha enabled.
Just checked with XaReg and only XWDPv12 was not so set. It FAILed when I set it.

Even tried with Xara Xtreme 5, that FAILed but I expected it to as it doesn't have an Alpha channel setting.

@Egg, all your Bitmap Properties views are demonstrating is that your XDA recognised FF but is rejecting the others' Alpha channel, thinking it garbage.
It looks like a refactoring exercise that failed to understand how the real world implemented the standard (badly) and that the prior iteration was more accommodating..

but it does not explain:

No it doesn't HD. Neither does it explain if I save the image from Chrome or Edge and import it into Xara it imports as a 32bit Standard Bitmap with an Alpha Channel but if I Copy & Paste it from either those two it imports as 24 bit JPG without Alpha Channel. I would think this is more a Windows issue than a specific browser issue.

EDIT: Cross-posting here Acorn. Googling this issue indicates it's far more widespread than XDA. It seems to occur within PS applications as well as others. Also whether Alpha Channels are being used (32bit) or Alphas are being applied to 24 bit channels.

I have noticed that if the pasteboard is colored black for instance and this image is then saved as a png to the desktop and opened with something like Irfanview there seems to be a very definite black background whereas if the pasteboard is not colored and remains white the image exports correctly with no background. please correct me if I am wrong.

[handrawn]

the black is when there is no alpha channel larry - without any information to define the transparency it defaults to black, ie 'no colour'

Thank you handrawn.
