It should actually save a character in the bitmap file rather its just outputting a black filled rectangle... pls advice me wats wrong in the code...i have also tried using lockbits and unlockbits to draw a string..CString szFile;m_edtFile.GetWindowText(szFile);Gdiplus::Status nResults = m_fontcollection.AddFontFile(szFile);if (nResults != Gdiplus::Ok){ MessageBox(L"Font add fails", L"Error");}CPaintDC dc(this);using namespace Gdiplus;Gdiplus::Bitmap bitmap(L"C:\\Users\\dc230\\Desktop\\New folder\\map.bmp");Graphics graphics(dc.m_hDC);graphics.FromImage(&bitmap);graphics.SetSmoothingMode(SmoothingModeAntiAlias); //sets the rendering quality of the Graphics objectgraphics.SetTextRenderingHint(TextRenderingHintSingleBitPerPixelGridFit); //method to specify the type of antialiasing (if any) applied to textSolidBrush brush(Color(255,255,255));FontFamily fontFamily;int nNumFound=0;m_fontcollection.GetFamilies(1,&fontFamily,&nNumFound);if (nNumFound > 0){ Gdiplus::Font font(&fontFamily,28,FontStyleRegular,UnitPixel); StringFormat strformat; strformat.SetAlignment(StringAlignmentCenter); wchar_t buf[] = {L"A"}; RectF therect; therect.Height = 10; therect.Width = 10; therect.X = 5; therect.Y = 5; Gdiplus::Status st =graphics.DrawString(buf,wcslen(buf),&font,therect,&strformat,&brush); graphics.Save(); Gdiplus::Bitmap b(100,100,&graphics); graphics.FromImage(&b); Gdiplus::BitmapData bmpd= {}; Rect therect1; therect.Height = 50; therect.Width = 30; therect.X = 20; therect.Y = 10; bitmap.LockBits(&therect1, ImageLockModeWrite,PixelFormat32bppARGB,&bmpd); ::glTexImage2D( GL_TEXTURE_2D,0,GL_RGBA ,50,50,0,GL_RGBA,GL_BITMAP,0); bitmap.UnlockBits(&bmpd); // Rotate bitmap 180 degrees b.RotateFlip(Rotate180FlipNone); if (b.GetLastStatus() == Ok) { EncoderParameters pEncoderParameters; pEncoderParameters.Count = 1; pEncoderParameters.Parameter[0].Guid = EncoderCompression; pEncoderParameters.Parameter[0].Type = EncoderParameterValueTypeLong; pEncoderParameters.Parameter[0].NumberOfValues = 1; // Save the image as a bmp ULONG compression = EncoderValueCompressionRle; pEncoderParameters.Parameter[0].Value = &compression; CLSID encoderClsid; GetEncoderClsid(L"image/bmp", &encoderClsid); b.Save(L"C:\\Users\\dc230\\Desktop\\New folder\\map1.bmp",&encoderClsid, &pEncoderParameters); MessageBox(L"Image Got Saved !"); } else { MessageBox(L"Unable to save the bitmap"); }}推荐答案 这篇关于Gdiplus抽绳到位图的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
