Dear all, I noticed in the latest R version (R.2.12.1) that the readPNG gives following warning when running the example code in the help file (or when using any other png for that matter) :
50: In rasterImage(img, 1.2, 1.27, 1.8, 1.73) : Per-pixel alpha not supported on this device No picture is shown, and code I used to be able to run, doesn't run any more. > sessionInfo() R version 2.12.1 (2010-12-16) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C LC_TIME=English_United States.1252 attached base packages: [1] grDevices datasets splines graphics stats tcltk utils methods base other attached packages: [1] png_0.1-2 svSocket_0.9-51 TinnR_1.0.3 R2HTML_2.2 Hmisc_3.8-3 survival_2.36-2 loaded via a namespace (and not attached): [1] cluster_1.13.2 grid_2.12.1 lattice_0.19-13 svMisc_0.9-61 tools_2.12.1 -- Joris Meys Statistical consultant Ghent University Faculty of Bioscience Engineering Department of Applied mathematics, biometrics and process control tel : +32 9 264 59 87 joris.m...@ugent.be ------------------------------- Disclaimer : http://helpdesk.ugent.be/e-maildisclaimer.php ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
