By default PETSc creates a separate color 35 for its windows, you must put the mouse into the graphics 36 window to see the correct colors. This options forces 37 PETSc to use the default colormap which will usually result 38 in bad contour plots. 39 . -draw_fast - Does not create colormap for contour plots. 40 . -draw_double_buffer - Uses double buffering for smooth animation. 41 - -geometry - Indicates location and size of window. 42 43 Level: beginner 44 45 Notes: 46 If `x` and `y` are both `PETSC_DECIDE` then PETSc places the window automatically. 47 48 When finished with the drawing context, it should be destroyed 49 with `PetscDrawDestroy()`. 50 51 Fortran Notes: 52 Whenever indicating null character data in a Fortran code, 53 `PETSC_NULL_CHARACTER` must be employed; using NULL is not 54 correct for character data! Thus, `PETSC_NULL_CHARACTER` can be 55 used for the display and title input parameters. 56 57 .seealso: `PetscDrawFlush()`, `PetscDrawDestroy()`, `PetscDrawCreate()`, `PetscDrawOpnOpenGL()` 58 @*/ 59 PetscErrorCode PetscDrawOpenX(MPI_Comm comm, const char display[], const char title[], int x, int y, int w, int h, PetscDraw *draw) 60 { 61 PetscFunctionBegin; 62 PetscCall(PetscDrawCreate(comm, display, title, x, y, w, h, draw)); 63 PetscCall(PetscDrawSetType(*draw, PETSC_DRAW_X)); 64 PetscFunctionReturn(PETSC_SUCCESS); 65 } 66
