Windows Resource Reader

[JeffM2501]

Returns the raw data for a resource embedded in a windows resource. does not need Windows.h so it can be used in any raylib file

C++ version (it uses a reference)

#include "resource.h"   // your resource header

#if defined(__cplusplus)
extern "C" {            // Prevents name mangling of functions
#endif
	void* FindResourceA(void* hModule, const char* lpName, const char* lpType);
	unsigned long SizeofResource(void* hModulhModule, void* hResInfo);
	void* LoadResource(void* hModule, void* hResInfo);
	unsigned char* LockResource(void* hResData);
#define MAKEINTRESOURCEA(i) ((const char*)((unsigned long*)((unsigned short)(i))))
#if defined(__cplusplus)
}
#endif

unsigned char* ReadResource(int resourceId, const char* resourceType, int& dataSize)
{
	void* hRes = FindResourceA(nullptr, MAKEINTRESOURCEA(resourceId), resourceType);
	dataSize = SizeofResource(nullptr, hRes);

	void* hResData = LoadResource(nullptr, hRes);
	return LockResource(hResData);
}

Example Usage

int resourceSize = 0;
Image img = LoadImageFromMemory(".png", ReadResource(IDB_PNG2, "PNG", resourceSize ), resourceSize );

C version (uses a pointer)

#include "resource.h"   // your resource header

#if defined(__cplusplus)
extern "C" {            // Prevents name mangling of functions
#endif
	void* FindResourceA(void* hModule, const char* lpName, const char* lpType);
	unsigned long SizeofResource(void* hModulhModule, void* hResInfo);
	void* LoadResource(void* hModule, void* hResInfo);
	unsigned char* LockResource(void* hResData);
#define MAKEINTRESOURCEA(i) ((const char*)((unsigned long*)((unsigned short)(i))))
#if defined(__cplusplus)
}
#endif

unsigned char* ReadResource(int resourceId, const char* resourceType, int* dataSize)
{
	void* hRes = FindResourceA(nullptr, MAKEINTRESOURCEA(resourceId), resourceType);
	dataSize = SizeofResource(nullptr, hRes);

	void* hResData = LoadResource(nullptr, hRes);
	return LockResource(hResData);
}

Example Usage

int resourceSize = 0;
Image img = LoadImageFromMemory(".png", ReadResource(IDB_PNG2, "PNG", &resourceSize ), resourceSize );
