By default PETSc creates a separate color 36 for its windows, you must put the mouse into the graphics 37 window to see the correct colors. This options forces 38 PETSc to use the default colormap which will usually result 39 in bad contour plots. 40 . -draw_fast - does not create colormap for countour plots 41 . -draw_double_buffer - Uses double buffering for smooth animation. 42 - -geometry - Indicates location and size of window 43 44 Level: beginner 45 46 Note: 47 When finished with the drawing context, it should be destroyed 48 with PetscDrawDestroy(). 49 50 Note for Fortran Programmers: 51 Whenever indicating null character data in a Fortran code, 52 PETSC_NULL_CHARACTER must be employed; using NULL is not 53 correct for character data! Thus, PETSC_NULL_CHARACTER can be 54 used for the display and title input parameters. 55 56 Concepts: X windows^drawing to 57 58 .seealso: PetscDrawSynchronizedFlush(), PetscDrawDestroy(), PetscDrawCreate(), PetscDrawOpnOpenGL() 59 @*/ 60 PetscErrorCode PetscDrawOpenX(MPI_Comm comm,const char display[],const char title[],int x,int y,int w,int h,PetscDraw *draw) 61 { 62 PetscErrorCode ierr; 63 64 PetscFunctionBegin; 65 ierr = PetscDrawCreate(comm,display,title,x,y,w,h,draw);CHKERRQ(ierr); 66 ierr = PetscDrawSetType(*draw,PETSC_DRAW_X);CHKERRQ(ierr); 67 PetscFunctionReturn(0); 68 } 69 70 71 72 73 74 75 76 77 78
