特性

  • Background Bitmap and Transparency Mask - PDF supports transparency masks, background isolated and knockout group features while rendering images in PDF. GcImaging now also includes the above features through a new API added to BitmapRenderer class to draw graphics, text and images to GcBitmapGraphics objects.
  • Blend Mode - While earlier versions of GcImaging supported blend modes when combining images (i.e. the GcBitmap.CompositeAndBlend() method), users can now set a blend mode on GcBitmapGraphics or BitmapRenderer. That blend mode will affect all bitmap, including drawing graphic primitives, images, and text. In total, there are 16 types of Blend Modes supported in GcImaging.
  • Background Bitmap - When drawing semi-transparent graphic objects, the resulting color of a pixel is a combination of the target bitmap pixel's color and the color of the graphic object's pixel. If the new BackgroundBitmap property is set on the BitmapRenderer, the pixels of that bitmap will be used instead of the target bitmap's pixels to determine the color. Use background bitmaps to support isolated and knockout transparency groups (as defined in the PDF specification) when rendering PDFs to images.
  • Transparency Mask - Another object added to BitmapRenderer class is the TransparencyMaskBitmap object, which provides a transparency mask for all drawing and filling operations. This helps you apply transparency together with other effects, such as blend mode or opacity.
