How to copy pictures to clipboard

Hi,

Call TChromium.DownloadImage to download the image and implement the TChromium.OnDownloadImageFinished event to get the image data.

Then you only need to call TCefImageRef.GetAsBitmap to get the binary data and copy it to the clipboard.

The MiniBrowser demo uses TChromium.DownloadImage to download a sample image.

I mean: copy the picture from the right-click menu

You can add a custom context menu option called "Copy image to clipboard" that downloads the image and copies the image data to the clipboard.

See the MiniBrowser demo to know how to add a custom context menu option.

The MiniBrowser demo uses TChromium.DownloadImage to download a sample image.

TempBinValue :=image.GetAsBitmap(1,CEF_COLOR_TYPE_RGBA_8888, CEF_ALPHA_TYPE_OPAQUE, TempWidth, TempHeight );
TempBinValue :=image.GetAsBitmap(1,aTempTCefColorType ,aTempTCefAlphaType, TempWidth, TempHeight );
all of these cannot work.
image.GetAsJpeg(1,0, TempWidth, TempHeight); the quality is very poor!

The sample didn't have code for TCefImageRef.GetAsBitmap and copy it to the clipboard,
May you write some example code, thank you very much!

Use TChromiumCore.StartDownload with the image url and save it to a temporary directory.
That way you will have the original image without any quality loss due to compression.

Is this the only way? It may be possible to downto a stream then copy to clipbord?

There are several ways to get the images but this is the easiest method and it also gives the best image quality.

Thank you very much!

But how to download this?
