...tting to a file, `quartz(file = 'test.pdf', type = 'pdf')`, it will produce horizontal reflections and ignore vertical ones. When the `xlim` or `ylim` is reversed, negative widths and heights are passed to the C function `device_Raster`, which is not a behavior documented in `R_ext/GraphicsDevice.h`. Also, the values of `x` and `y` passed to `device_Raster` will be shifted by the width or height of the image such that the coordinates no longer reference the bottom-left corner of the image as `R_ext/GraphicsDevice.h` says they should. Given the inconsistencies in documentation and behavior,...

Dear list, Whenever the flag "-Wstrict-prototypes" is set in gcc, compiling code that includes headers in lib/R/include generates often warnings (example with R-2.6.1: Rinternals.h:560: warning: function declaration isn't a prototype ). All such warnings I looked at were about functions with empty signatures declared as "bar foo();" rather than "bar

Partly about new features and partly about old features that are not being used. R_exts/GraphicsEngine.h says /* * The current graphics engine (including graphics device) API version * MUST be integer * * This number should be bumped whenever there are changes to * GraphicsEngine.h or GraphicsDevice.h so that add-on packages * that compile against these headers (graphics systems such as * graphics and grid; graphics devices such as gtkDevice, RSvgDevice) * can detect any version mismatch. * * Version 1: Introduction of the version number. * Version 2: GEDevDesc *dd dropped from...

Hello. I'm looking for documentation about the graphic device model in R. I would understand it in the details, but it seems a bit complex :) Thanks for any documents which will help me. Laurent

Hi, I read the 2000 thread on a MetaPost device in R. If I understand correctly, the main problem with the concept is that R wants the device driver to give back information on the size of strings/labels. To the bet of my knowledge, MetaPost _does_ make it possible to measure the bounding box of text (see section 7.3: Measuring text in the MetaPost manual). For example, one could get the size of
