Page 178 of 750
SI32 pdfCircleAnnot(
const PPDF* IPDF,
// Instance pointer
double PosX,
// y-coordinate of the annotation
double PosY,
// x-coordinate of the annotation
double Width,
// Width of the annotation
double Height,
// Height of the annotation
double LineWidth,
// Line width of the circle or ellipse
UI32 FillColor,
// Fill color or NO_COLOR. See description
UI32 StrokeColor,
// Stroke color or NO_COLOR. See description
TPDFColorSpace CS,
// Color space of the fill and stroke colors
const char* Author,
// Optional author
const char* Subject, // Optional subject
const char* Comment) // Optional comment
The function draws a circle annotation on the current open page. If the parameters Width and Height
are equal the function draws a circle, an ellipse otherwise. If the annotation should be drawn without
a border, set the parameter LineWidth to zero or StrokeColor to the special constant NO_COLOR.
If the interior should be transparent set FillColor to the special constant NO_COLOR.
Although the line width can be set to any positive floating point value, Adobe’s Acrobat or Reader
restrict the line width to 0 through 12 units. The line width should be restricted in the same way to
avoid issues in Adobe viewer products.
This function is implemented in an Ansi and Unicode compatible variant. Ansi strings are
interpreted in the Windows code page 1252.
Return values:
If the function succeeds the return value is the annotation handle, a value greater or equal zero. If the
function fails, the return value is a negative error code.
SI32 pdfClearAutoTemplates(
const PPDF* IPDF) // Instance pointer
This function deletes the array of templates which are automatically added to newly created pages.
See AutoTemplate() for further information.
Return values:
If the function succeeds the return value is 1. If the function fails the return value is 0.
