Module draw Methods

AcquireDrawInfo() returns a DrawInfo structure properly initialized.

The format of the AcquireDrawInfo method is:

  DrawInfo *AcquireDrawInfo(void)

CloneDrawInfo() makes a copy of the given draw info structure. If NULL is specified, a new image info structure is created initialized to default values.

The format of the CloneDrawInfo method is:

  DrawInfo *CloneDrawInfo(const ImageInfo *image_info,
    const DrawInfo *draw_info)

A description of each parameter follows:

image_info

the image info.

draw_info

the draw info.

DestroyDrawInfo() deallocates memory associated with an DrawInfo structure.

The format of the DestroyDrawInfo method is:

  DrawInfo *DestroyDrawInfo(DrawInfo *draw_info)

A description of each parameter follows:

draw_info

the draw info.

DrawAffineImage() composites the source over the destination image as dictated by the affine transform.

The format of the DrawAffineImage method is:

  MagickBooleanType DrawAffineImage(Image *image,const Image *source,
    const AffineMatrix *affine)

A description of each parameter follows:

image

the image.

source

the source image.

affine

the affine transform.

DrawClipPath() draws the clip path on the image mask.

The format of the DrawClipPath method is:

  MagickBooleanType DrawClipPath(Image *image,const DrawInfo *draw_info,
    const char *name)

A description of each parameter follows:

image

the image.

draw_info

the draw info.

name

the name of the clip path.

DrawImage() draws a graphic primitive on your image. The primitive may be represented as a string or filename. Precede the filename with an "at" sign (@) and the contents of the file are drawn on the image. You can affect how text is drawn by setting one or more members of the draw info structure.

The format of the DrawImage method is:

  MagickBooleanType DrawImage(Image *image,const DrawInfo *draw_info)

A description of each parameter follows:

image

the image.

draw_info

the draw info.

DrawGradientImage() draws a linear gradient on the image.

The format of the DrawGradientImage method is:

  MagickBooleanType DrawGradientImage(Image *image,
    const DrawInfo *draw_info)

A description of each parameter follows:

image

the image.

_info

the draw info.

DrawPatternPath() draws a pattern.

The format of the DrawPatternPath method is:

  MagickBooleanType DrawPatternPath(Image *image,const DrawInfo *draw_info,
    const char *name,Image **pattern)

A description of each parameter follows:

image

the image.

draw_info

the draw info.

name

the pattern name.

image

the image.

DrawPrimitive() draws a primitive (line, rectangle, ellipse) on the image.

The format of the DrawPrimitive method is:

  MagickBooleanType DrawPrimitive(Image *image,const DrawInfo *draw_info,
    PrimitiveInfo *primitive_info)

A description of each parameter follows:

image

the image.

draw_info

the draw info.

primitive_info

Specifies a pointer to a PrimitiveInfo structure.

GetAffineMatrix() returns an AffineMatrix initialized to the identity matrix.

The format of the GetAffineMatrix method is:

  void GetAffineMatrix(AffineMatrix *affine_matrix)

A description of each parameter follows:

affine_matrix

the affine matrix.
