#include <PDFDraw.h>
List of all members.
Utility methods are provided to export PDF pages to various raster formats as well as to convert pages to GDI+ bitmaps for further manipulation or drawing.
Sets the output image resolution.
DPI stands for Dots Per Inch. This parameter is used to specify the output image size and quality. A typical screen resolution for monitors these days is 92 DPI, but printers could use 200 DPI or more.
if you would like to rasterize extremely large bitmaps (e.g. with resolutions of 2000 DPI or more) it is not practical to use PDFDraw directly because of the memory required to store the entire image. In this case, you can use PDFRasterizer directly to generate the rasterized image in stripes or tiles.
Selects the page box/region to rasterize.
Flips the vertical (i.e.
Y) axis of the image.
Sets the rotation value for this page.
Enable or disable annotation and forms rendering.
By default, all annotations and form fields.
A utility method to export the given PDF page to an image file.
By default, the function exports to PNG.
Gets a GDI+ bitmap for the given page.
this method is only supported on Windows platforms. If your application is running on a Windows platform, you can select GDI+ rasterizer with SetRasterizerType() and e_GDIPlus type.
Gets the raw rasterized image data for the given image.
Sets the error handling function to be called in case an error is encountered during page rendering.
