Use magick ++ 6.8.5 in MFC

Magick ++ is the c ++ encapsulation of the ImageMagick Image Library. ImageMagick is a software suite that allows you to create, edit, synthesize, and convert image formats.
Compilation steps:
1. Download the source code package from http://www.imagemagick.org/download/windows/imagemagick-windows.zip;
2. decompress the package to the folder and openConfigure.exeFile, press "Next" to enter the configuration interface, you can set the compilation type and compilation options, here I use the default compilation type, that is, dynamic multi-threaded DLL runtimes type, select the default compilation option, as shown in:

3. Click "Next" until "complete", and you can see that the system automatically generates the file in the ".. \ visualmagick" directory"Visualdynamicmt. sln"File (this name varies depending on different compilation types), open it with vs2008, right-click the" all "project in the solution, and select" clean ", then select "build ". After compilation, you can view the generated file in the "bin" folder under ".. \ visualmagick" and "lib" folder.
4. Open the "\ visualmagick \ bin" directory"Imdisplay.exe", Load any image (Chinese path not supported) to see if it can be properly displayed, as shown in:

The following describes how to use magick ++ in vs2008.
1. Create a Win32 console project, select "Empty Project", and remove "precompiled header". The project name is testmagick;
2. Add a new CPP file named test. cpp. The Code is as follows:

1 2 3 4 5 6 7 8 9 10 11

# Include <magick ++. h> Using namespace magick; Int main (INT/* argc */, char ** argv) { Initializemagick (* argv ); Image image ("100x100", "White "); Image. pixelcolor (49, 49, "Red "); Image. Write ("red_pixel.png "); Return 0; }

The code function is to create a x pixel white background image with the center pixel in red.
3. right-click Project → "properties" → "C/C ++", fill in "general" → "Additional include directories" to "X: \ ImageMagick-6.8.5"; "X: \ ImageMagick-6.8.5 \ magick ++ \ Lib "," Preprocessor "→" Preprocessor definitions "add fill"; _ VisualC _; _ crt_secure_no_warnings; _ crt_nonstdc_no_warnings ". "Linker", "general" → "Additional
Library directories "fill in" X: \ ImageMagick-6.8.5 \ visualmagick \ Lib "," input "→" additional dependencies "fill in" core_db_magick ++ _. lib ". "Debugging" → "working directory" fill in "X: \ ImageMagick-6.8.5 \ visualmagick \ bin ".
4. Compile and run the program. You can see the generated file in the ".. \ visualmagick \ bin" directory.Red_pixel.pngFile.

The following describes how to use magick ++ in MFC.
1. Create an MFC single-document application named testmagickmfc;
2. InStdafx. hFile, add the following code:

1

# Include <magick ++. h>

3. InTestmagickmfc. cppAdd the following code to the initinstance function:

1

Magick: initializemagick (null );

4. InTestmagickmfcview. hAdd the following code to the file:

1 2 3

Magick: Image m_pimage; CDC * moffscreendc; Void dodisplayimage (CDC * PDC );

5. InTestmagickmfcview. cppAdd the following code to file modification:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143
