PgContrastBevelBox(), PgContrastBevelBoxCx()

Draw a beveled box with gradients and a given level of contrast

Synopsis:

int PgContrastBevelBox( PhPoint_t *ul,
                        PhPoint_t *lr,
                        PgColor_t flat_color,
                        int contrast,
                        short depth,
                        short width,
                        PgColor_t outline_color,
                        PgColor_t inline_color,
                        int flags );

int PgContrastBevelBoxCx( void *dc,
                          PhPoint_t *ul,
                          PhPoint_t *lr,
                          PgColor_t flat_color,
                          int contrast,
                          short depth,
                          short width,
                          PgColor_t outline_color,
                          PgColor_t inline_color,
                          int flags );

Arguments:

dc

PgContrastBevelBoxCx() only. A void pointer to any type of draw context. Examples of draw contexts are:

• a PhDrawContext_t returned by PhDCCreate()
• a PmMemoryContext_t returned by PmMemCreateMC()
• a PpPrintContext_t returned by PpCreatePC()
• a PdOffscreenContext_t returned by PdCreateOffscreenContext()

ul, lr

Pointers to PhPoint_t that define the upper left and lower right corners of the beveled box.

flat_color

A PgColor_t that defines the middle/neutral color in the bevel-gradients, and the box's fill color if you set Pg_BVB_FILL in the flags.

contrast

The contrast in the light-to-flat and flat-to-dark gradients, in the range 0 (low/no contrast) to 255 (high/max contrast).

depth

The number of isochrome lines in the light-to-flat and flat-to-dark bevel gradients. The sign of the depth controls the location of an (imaginary) light source:

• Positive depth -- illuminated from the top left.
• Negative depth -- illuminated from the bottom right.

width

The width of the bevel, not including outlines and inlines.

outline_color

The color of the outline rectangle.

inline_color

The color of the inline rectangle.

flags

Flags that affect the appearance of the beveled box:

• Pg_BVB_FILL -- fill the beveled box with flat-color.
• Pg_BVB_FULL_GRADIENTS -- each bevel has two gradients: light-to-flat and flat-to-dark. If this isn't set, the bevels have only one gradient; see the illustration above.
• Pg_BVB_DRAW_LEFT -- draw the left edge of the beveled box.
• Pg_BVB_DRAW_RIGHT -- draw the right edge of the beveled box.
• Pg_BVB_DRAW_TOP -- draw the top edge of the beveled box.
• Pg_BVB_DRAW_BOTTOM -- draw the bottom edge of the beveled box.
• Pg_BVB_DRAW_ALL -- draw all edges of the beveled box.
• Pg_BVB_DRAW_BITS -- turn on all of the above flag bits.

Library:

ph

Description:

These functions draw a beveled box with gradients and a given level of contrast. PgContrastBevelBox() works on the current draw context, while you can specify the draw context for PgContrastBevelBoxCx().

Returns:

0

Success.

-1

An error occurred.

Classification:

Photon

Safety:
Interrupt handler	No
Signal handler	No
Thread	No
