## Description

## Details

### enum GnomePrintReturnCode

    typedef enum {
    	GNOME_PRINT_OK = 0,
    	GNOME_PRINT_ERROR_UNKNOWN        = -1,
    	GNOME_PRINT_ERROR_BADVALUE       = -2,
    	GNOME_PRINT_ERROR_NOCURRENTPOINT = -3,
    	GNOME_PRINT_ERROR_NOCURRENTPATH  = -4,
    	GNOME_PRINT_ERROR_TEXTCORRUPT    = -5,
    	GNOME_PRINT_ERROR_BADCONTEXT     = -6,
    	GNOME_PRINT_ERROR_NOPAGE         = -7,
    	GNOME_PRINT_ERROR_NOMATCH        = -8
    } GnomePrintReturnCode;

### GnomePrintContext

    typedef struct _GnomePrintContext GnomePrintContext;

### gnome_print_context_new ()

    GnomePrintContext *  gnome_print_context_new            (GnomePrintConfig *config);

Create new printing context from config. You have to have set all the options/settings beforehand, as changing the config of an existing context has undefined results.

Also, if creating the context by hand, it completely ignores layout and orientation value. If you need those, use GnomePrintJob. The later also can create output context for you, so in most cases you may want to ignore gnome_print_context_new at all.

`config` : | GnomePrintConfig object to query print settings from
Returns : | The new GnomePrintContext or NULL on error

### gnome_print_context_close ()

    gint                gnome_print_context_close           (GnomePrintContext *pc);

Informs given GnomePrintContext that application has finished print job. From that point on, `pc` has to be considered illegal pointer, and any further printing operation with it may kill application. Some printing contexts may not start printing before context is closed.

`pc` : | A GnomePrintContext
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_newpath ()

    gint                gnome_print_newpath                 (GnomePrintContext *pc);

Resets currentpath to empty path. As currentpoint is defined as the last point of open path segment, is also erases currentpoint.

`pc` : | A GnomePrintContext
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_moveto ()

    gint                gnome_print_moveto                  (GnomePrintContext *pc,
                                                             gdouble x,
                                                             gdouble y);

Starts new subpath in currentpath with coordinates `x`,`y`. Moves currentpoint to `x`,`y`.

`pc` : | A GnomePrintContext
`x` : | X position in user coordinates
`y` : | Y position in user coordinates
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_lineto ()

    gint                gnome_print_lineto                  (GnomePrintContext *pc,
                                                             gdouble x,
                                                             gdouble y);

Adds new straight line segment from currentpoint to `x`,`y` to currentpath. Moves currentpoint to `x`,`y`. If currentpoint is not defined, returns GNOME_PRINT_ERROR_NOCURRENTPOINT.

`pc` : | A GnomePrintContext
`x` : | X position in user coordinates
`y` : | Y position in user coordinates
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_curveto ()

    gint                gnome_print_curveto                 (GnomePrintContext *pc,
                                                             gdouble x1,

Draws RGB color image with transparency channel image into unit square (0,0 - 1,1) in current coordinate system. Image buffer has to be 4 bytes per pixel, order RGBA, with value 255 marking maximum and 0 minimum value. Alpha value 255 means full opacity, 0 full transparency.

`pc` : | A GnomePrintContext
`data` : | Pointer to image pixel buffer
`width` : | Image buffer width
`height` : | Image buffer height
`rowstride` : | Image buffer rowstride
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_beginpage ()

    gint                gnome_print_beginpage               (GnomePrintContext *pc,
                                                             const guchar *name);

Starts new output page with `name`. Naming is used for interactive contexts like GnomePrintPreview and Document Structuring Convention conformant PostScript output. This function has to be called before any drawing methods and immediately after each gnome_print_showpage albeit the last one. It also resets graphic state values (transformation, color, line properties, font), so one has to define these again at the beginning of each page.

`pc` : | A GnomePrintContext
`name` : | Name of the page, NULL if you just want to use the page number of the page
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_showpage ()

    gint                gnome_print_showpage                (GnomePrintContext *pc);

Finishes rendering of current page, and marks it as shown. All subsequent drawing methods will fail, until new page is started with gnome_print_newpage. Printing contexts may process drawing methods differently - some do rendering immediately (like GnomePrintPreview), some accumulate all operators to internal stack, and only after gnome_print_showpage is any output produced.

`pc` : | A GnomePrintContext
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_line_stroked ()

    gint                gnome_print_line_stroked            (GnomePrintContext *pc,
                                                             gdouble x0,
                                                             gdouble y0,
                                                             gdouble x1,
                                                             gdouble y1);

A convenience function to draw a line. Uses gnome_print_stroke to do the actual work.

`pc` : | A GnomePrintContext
`x0` : | X position of start point in user coordinates
`y0` : | Y position of start point in user coordinates
`x1` : | X position of end point in user coordinates
`y1` : | Y position of end point in user coordinates
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_rect_stroked ()

    gint                gnome_print_rect_stroked            (GnomePrintContext *pc,
                                                             gdouble x,
                                                             gdouble y,
                                                             gdouble width,
                                                             gdouble height);

A convenience function to draw a rectangle. Uses gnome_print_stroke to do the actual work.

`pc` : | A GnomePrintContext
`x` : | X position of origin of rectangle in user coordinates
`y` : | Y position of origin of rectangle in user coordinates
`width` : | Width of the rectangle
`height` : | Height of the rectange
Returns : | GNOME_PRINT_OK or positive value on success, negative error code on failure.

### gnome_print_rect_filled ()

    gint                gnome_print_rect_filled             (GnomePrintContext *pc,
                                                             gdouble x,
                                                             gdouble y,
