IIRC it was in Smalltalk-80: the language and its implementation from the 1980s. Or perhaps one of the other two books in that series.

  Yup, there it is. (Pages 430-432 of that PDF file, figures 20.8 through 20.10) So I guess that 1983 is the earliest year found so far.

      A decade? That reference gives a date of 1981 for the bitmap-rotating algorithm: > The Byte article on “The Smalltalk Graphics Kernel” [Ingalls 1981] details Smalltalk methods that, with BitBlt at their core, can lay out and display text, draw lines, and magnify and rotate images—each in little more than a dozen lines of code. […] > Daniel H. H. Ingalls. 1981. The Smalltalk Graphics Kernel. Byte 6, 8, 168–194. https://archive.org/details/byte-magazine-1981-08/page/n181/mode/2up https://archive.org/details/byte-magazine-1981-08/page/n181/... In that reference, the bitmap rotation is on page 188 in the original publication (page 202 of the archived document).

        That's because the Byte issue was the "coming out" for Smalltalk -- a description of their work but not necessarily new work. Bitblt was first implemented in Smalltalk-74 I believe (meaning ~1974)

        Do you have a reference to show that image rotation using BitBlt was written any earlier than 1981?

        page 28 '… when I gave a demo at one of the CSL “Dealer” meetings at Parc that featured overlapping windows with BitBlt in Smalltalk-74.'

        They only write that BitBlt was demonstrated, not image rotation with BitBlt. So as far as we know currently, the 1981 article was the first mention of image rotation.
