win32 – use GDI+ to play gif pictures

I encountered such a problem when I was doing a case today, so I recorded it. Codeproject has a similar case, but it is compiled using the MFC template. Because we only need win32 programs, so…. the code is as follows: CodeProject: Play GIF using GDI+ The other is implemented using double buffering, I have […]

Use GDI+ (WIC) to load 32-bit bitmap or PNG image (with transparency channel)

#include <windows.h> #include <gdiplus.h> HBITMAP LoadBitmapFromResource(DWORD ResourceID, bool transparent = true) { HANDLE hGlobal = NULL; ULONG_PTR GDIToken = 0; Gdiplus::Image* Img = NULL; Gdiplus::GdiplusStartupInput GDIStartInput = NULL; Gdiplus::GdiplusStartup( &GDIToken, &GDIStartInput, NULL); HRSRC hResource = FindResource(NULL, MAKEINTRESOURCE(ResourceID), “BINARY”); if (!hResource) {<!– –>return NULL;} HGLOBAL hFileResource = LoadResource(NULL, hResource); if (!hFileResource) {<!– –>return NULL;} LPVOID lpFile […]

Win32 – Use of GDI+ Gaussian Blur

However, the relevant documentation of GDI+ has some API instructions about Gaussian blur, see the link below: Blur class (gdipluseffects.h) Using the Blur class, you can apply a Gaussian blur effect to a bitmap and specify the nature of […]
