Dear gang, It seems that ConTeXt does not currently implement optical scaling for Latin Modern -- at least not by default. For example: ======= \startTEXpage[offset=1em] Test {\tfa Test} {\tfb Test} {\tfc Test} {\tfd Test} {\tfx Test} {\tfxx Test} \stopTEXpage ======= In the log we have ======= mkiv lua stats > loaded fonts: 2 files: latinmodern-math.otf, lmroman10-regular.otf ======= Is this behavior intentional? The needed sizes are certainly available (/texmf/fonts/data/gust/lm). This issue came up while trying to test/implement something else. Although Computer Modern / Latin Modern is perhaps hardly popular for contemporary publication work, a full implementation of the full palette of optical sizes is still useful as a benchmark, etc. Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523
