# Ifndef ULONG_PTR# Define ULONG_PTR unsigned long *# Include "GdiPlus. h"Using namespace Gdiplus;# Pragma comment (lib, "gdiplus. lib ")# Endif
The following member variables are defined in the Class header file to initialize the usage and end use of GDI +.
GdiplusStartupInput m_gdiplusStartupInput;ULONG_PTR m_gdiplusToken;

A short time ago, we found that an open-source Apache tool could convert PDF files into images. Without a jar package that directly transforms HTML into images, we could only save the country by curve.I forgot to introduce it. The package for converting PDF files to images is called apache product_box. The right side is the official website of product_box.The following code is directly pasted:[Java]Public void convertToTiff (String pdfFilePath, String character filename)Throws Exception {PDDocum

Create an all-empty graphic. Draw a graphic on it. Use black as a transparent color.
This new shape will be the same size as the original, the absolute position is the same, put it above
In the previous article, we talked about the implementation of HTML-to-PDF conversion. In another aspect of that requirement, the project requires page-to-image conversion, mainly JPG, Tiff, PNG format. I was a little confused, but it was never done last time. No suitable tool was found for conversion.
