NAMEpaint - Paint on an Image
SYNOPSISMagickBooleanType ColorFloodfillImage( Image *image, const DrawInfo *draw_info, const PixelPacket target, const long x_offset, const long y_offset, const PaintMethod method ); MagickBooleanType MatteFloodfillImage( Image *image, const PixelPacket target, const Quantum opacity, const long x_offset, const long y_offset, const PaintMethod method ); MagickBooleanType OpaqueImage( Image *image, const PixelPacket target, const PixelPacket fill ); MagickBooleanType TransparentImage( Image *image, const PixelPacket target, const Quantum opacity );
FUNCTION DESCRIPTIONS
ColorFloodfillImage
By default target must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. The fuzz member of image defines how much tolerance is acceptable to consider two colors as the same. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color for the purposes of the floodfill. The format of the ColorFloodfillImage method is: MagickBooleanType ColorFloodfillImage ( Image *image, const DrawInfo *draw_info, const PixelPacket target, const long x_offset, const long y_offset, const PaintMethod method ); A description of each parameter follows:
MatteFloodfillImage
By default target must match a particular pixel transparency exactly. However, in many cases two transparency values may differ by a small amount. The fuzz member of image defines how much tolerance is acceptable to consider two transparency values as the same. For example, set fuzz to 10 and the opacity values of 100 and 102 respectively are now interpreted as the same value for the purposes of the floodfill. The format of the MatteFloodfillImage method is: MagickBooleanType MatteFloodfillImage ( Image *image, const PixelPacket target, const Quantum opacity, const long x_offset, const long y_offset, const PaintMethod method ); A description of each parameter follows:
OpaqueImageOpaqueImage() changes any pixel that matches color with the color defined by fill. By default color must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. Fuzz defines how much tolerance is acceptable to consider two colors as the same. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color. The format of the OpaqueImage method is: MagickBooleanType OpaqueImage ( Image *image, const PixelPacket target, const PixelPacket fill ); A description of each parameter follows:
TransparentImageTransparentImage() changes the opacity value associated with any pixel that matches color to the value defined by opacity. By default color must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. Fuzz defines how much tolerance is acceptable to consider two colors as the same. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color. The format of the TransparentImage method is: MagickBooleanType TransparentImage ( Image *image, const PixelPacket target, const Quantum opacity ); A description of each parameter follows:
