My program is as following:
GLuint LoadGLTextures(const char *filename)
{
int status=FALSE;
AUX_RGBImageRec TextureImage=NULL;
GLuint texture=0;
ZeroMemory(&TextureImage,sizeof(void)*1);
// Load The Bitmap, Check For Errors, If Bitmap’s Not Found Quit
if ( TextureImage=LoadBMP( filename ) )
{ status=TRUE;
glGenTextures( 1,&texture);
// Typical Texture Generation Using Data From The Bitmap
glBindTexture( GL_TEXTURE_2D, texture );
glTexImage2D( GL_TEXTURE_2D, 0, 3, TextureImage->sizeX, TextureImage->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage->data );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR );
if ( TextureImage) {
if (TextureImage -> data) {
free( TextureImage-> data );
};
free( TextureImage);
};
};
glEnable( GL_TEXTURE_2D );
glBindTexture( GL_TEXTURE_2D,texture);
glMatrixMode(GL_MODELVIEW);
glTranslatef(0.0f,0.0f,-0.2f);
glBegin(GL_POLYGON);
glTexCoord2f( 0.0f, 0.0f );
glVertex3f( -0.6f, -0.5f, 0.5f );
glTexCoord2f( 1.0f, 0.0f );
glVertex3f( 0.6f, -0.5f, 0.5f );
glTexCoord2f( 1.0f, 1.0f );
glVertex3f( 0.6f, 0.5f, 0.5f );
glTexCoord2f( 0.0f, 1.0f );
glVertex3f( -0.6f, 0.5f, 0.5f );
glEnd();
glLoadIdentity();
return texture;
}
AUX_RGBImageRec * LoadBMP(const char *Filename)
{
FILE *File = NULL;
if ( !Filename ) {
return NULL;
};
File = fopen( Filename,“r” );
if ( File ) {
fclose( File );
return auxDIBImageLoad( Filename );
};
return NULL;
}
