I want to make a red texture image buffer. Would anyone help me to make it in right way. I have tried following:
std::vector<BYTE> redTexture(w*h*4);
const auto stride = w * 4;
BYTE* buf = redTexture.data();
for (int i = 0; i < h; ++i)
{
const auto redValue = Gdiplus::Color::Red;
memcpy(buf, &redValue, stride);
buf += stride;
}
I have solved the issue by doing the following:
CImage m_cImage;
// create a test image
m_cImage.Create(w, -h, 8 * 4); // 8 bpp * 4 channel
auto hdc = m_cImage.GetDC();
Gdiplus::Graphics graphics(hdc);
// Create a SolidBrush object.
Gdiplus::SolidBrush redBrush(Gdiplus::Color::Red);
// Fill the rectangle.
Gdiplus::Status status = graphics.FillRectangle(&redBrush, 0, 0, w, h);
TRY_CONDITION(status == Gdiplus::Status::Ok);
....
// Then saved the m_cImage.GetBits() to bmp file using Gdiplus::Bitmap
// and my expected texture is found
