    CairoContext::copyPath -- cairo_copy_path — Creates a copy of the current path

    설명

    객체 기반 형식 (method):

    public CairoPath CairoContext::copyPath ( void )

    절차식 형식:

    CairoPath cairo_copy_path ( CairoContext $context )

    Creates a copy of the current path and returns it to the user as a CairoPath. See CairoPath for hints on how to iterate over the returned data structure.

    This function will always return a valid CairoPath object, but the result will have no data, if either of the following conditions hold:

    • 1. If there is insufficient memory to copy the path. In this case CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY.
    • 2. If context is already in an error state. In this case CairoPath->status will contain the same status that would be returned by cairo_status().
    In either case, CairoPath->status will be set to CAIRO_STATUS_NO_MEMORY (regardless of what the error status in cr might have been).

    인수

    context

    A valid CairoContext object created with CairoContext::__construct() or cairo_create()

    반환값

    A copy of the current CairoPath in the context

    예제

    Example #1 객체 기반 형식

    <?php

    $surface     = new CairoImageSurface(CairoFormat::ARGB32, 50, 50);

    $context = new CairoContext($surface);

    var_dump($context->copyPath())

    ?>

    위 예제의 출력 예시:

    object(CairoPath)#3 (0) {
}

    Example #2 절차식 형식

    <?php

    $surface     = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 50, 50);

    $context = cairo_create($surface);

    var_dump(cairo_copy_path($context));

    ?>

    위 예제의 출력 예시:

    object(CairoPath)#3 (0) {
}
