Re: [Imtoolkit-users] Draw line on a image

[Antonio S. <sc...@te...>]

 Hi,

 Using the CD library. You can create a CD_IMAGERGB canvas using the
existing image buffers.

 Here is a sample in C:

imImage* image = *imImageCreate*(width, height, IM_RGB, IM_BYTE);
// Can also call *imImageAddAlpha* if alpha support is wanted
cdCanvas* canvas = cdCreateCanvasf(CD_IMAGERGB, "%dx%d %p %p %p",
width, height,
                                   image->data[0], image->data[1],
image->data[2]);cdCanvasLineStyle(canvas, CD_DASHED);
cdCanvasLine(canvas, 10, 10, 50, 50);
cdKillCanvas(canvas);
*imFileImageSave*(file_name, "PNG", image);*imImageDestroy*(image);

Best,
Scuri
