That is good. Just two comments: - in the patch 'redoSmooth' is incorrectly indented, that may indicate tab (which we do not want). - It makes sense to keep various graphics fixes together and do not split them into several tiny commit. In particular there is significant duplication and almost duplication in the code, so there is good chance that fix for one problem is also applicable in different place (or at least suggests a solution). Smaller number of bigger commits makes search to chanes easier. > However, if you save the image by clicking buttons in > the control panel, you can have the black and white image. > > As you can see that in process3d.c (responsible for the button > to save PS file): > > redoSmooth = yes; > drawViewport(PSoption); /* draw picture in PS; create ps script file > */ > > - Qian > > diff --git a/src/graph/view3D/write3d.c b/src/graph/view3D/write3d.c > index ac5a1210..9ccd4c32 100644 > --- a/src/graph/view3D/write3d.c > +++ b/src/graph/view3D/write3d.c > @@ -199,6 +199,7 @@ writeViewport (int thingsToWrite) > "/fricas3D.ps"); > if (PSInit(viewport->viewWindow,viewport->titleWindow) == psError) > return(-1); > + redoSmooth = yes; > drawViewport(PSoption); /* write new script file in /tmp */ > if (PSCreateFile(viewBorderWidth,viewport->viewWindow, > viewport->titleWindow, viewport->title) == > psError) > > -- > You received this message because you are subscribed to the Google Groups > "FriCAS - computer algebra system" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/fricas-devel/28e84d63-3d81-4be9-b89d-61501723828d%40gmail.com. -- Waldek Hebisch -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
