A screenshot on the clipboard didn't paste everywhere: - macOS: the Paste menu item (which takes Cmd+V there) was enabled for text only, so with nothing copied in the app Cmd+V did nothing; and arboard reads the pasteboard's TIFF only. The pasteboard's types now enable Paste, and its PNG, else TIFF, pastes as it is. - Windows: bitmaps came through CF_BITMAP and GetDIBits, which drops alpha. Paste now reads PNG, else CF_DIBV5, else CF_DIB, decoded with their colour masks and tables (a BMP file header in front, which image's headerless decoder gets wrong for masks after a BITMAPINFOHEADER), opaque when the alpha is zero throughout as screenshots leave it, capped at 32768 px a side. - Web: only SVG text pasted. The page's paste event now hands the first picture or file that is art to the app (VectorcraftApp::paste_from_host), pasted with the chord held, like the desktop's paste keys. - Linux reads image/png already; its Paste menu item still waits for text (no cheap way to ask arboard for a bitmap), the paste keys take one. Bitmaps paste as embedded images at the view centre, as before. Co-Authored-By: Claude Opus 5.5 <[email protected]>
