34 Read the current settings of a RastPort into variables.
35 The ti_Tag field specifies the attribute to read and the
36 ti_Data field points to an address where to store the result.
37 All results are stored as IPTRs!
40 rp = pointer to a RastPort structure
41 tags = pointer to a taglist specifying the attributes to read and
42 the addresses to store the results
45 RPTAG_Font (UBYTE) - Font for Text()
46 RPTAG_APen (UBYTE) - Primary rendering pen
47 RPTAG_BPen (UBYTE) - Secondary rendering pen
48 RPTAG_DrMd (UBYTE) - Drawing mode (graphics/rastport.h)
49 RPTAG_OutlinePen (UBYTE) - Area Outline pen
50 RPTAG_WriteMask (ULONG) - Bit Mask for writing
51 RPTAG_MaxPen (ULONG) - Maximum pen to render (see SetMaxPen())
53 MorphOS-compatible extensions:
55 RPTAG_FgColor (ULONG) - Primary rendering color in A8R8G8B8 format.
56 Only working on hicolor/truecolor bitmaps/screens.
57 RPTAG_BgColor (ULONG) - Secondary rendering color in A8R8G8B8 format.
58 Only working on hicolor/truecolor bitmaps/screens.
60 AmigaOSv4-compatible extensions:
62 RPTAG_RemapColorFonts (BOOL) - Automatically remap colorfonts to their color
63 on hicolor/truecolor screens.
65 AROS-specific extensions:
67 RPTAG_ClipRectangle (struct Rectangle *) - Rectangle to clip rendering to. Rectangle will
69 RPTAG_ClipRectangleFlags (LONG) - RPCRF_RELRIGHT | RPCRF_RELBOTTOM (see <graphics/rpattr.h>)
74 RPTAG_ClipRectangle and RPTAG_ClipRectangleFlags must not be
75 used on manually inited or cloned rastports. Instead the rastport
76 must have been created with CreateRastPort() or CloneRastPort().
81 RPTAG_SoftStyle and RPTAG_DrawBounds are not supported yet.
