It depends only on the IM main library. It is usefull for testing the drivers.</p> + <p>You can view the source code here: <a href="../download/im_copy.cpp">im_copy.cpp</a></p> + +<h3><code>proc_fourier</code></h3> + + <p>This is another command line application that process an image in the Fourier Frequency Domain. In this domain the + image is a map of the spatial frequencies of the original image. It depends on the IM main library and on the IM_FFTW + library. The FFTW is a very fast Fourier transform, but is contaminated by the GPL license, so everything must be also + GPL. To use it in a commercial application you must contact the MIT and pay for a commercial license.</p> + <p>Se also <a href="doxygen/group__transform.html)">Reference / Image Processing / Domain + Transform Operations</a>.</p> + <p>You can view the source code here: <a href="../download/proc_fourier.cpp">proc_fourier.cpp</a></p> + +<h3><code>im_view</code></h3> + + <p>This application uses IUP and CD to create a window with a canvas and draw the image into that canvas. It is a very + simple application, no zoom nor scrollbar management. The image is obtained from a file using the IM I/O functions, + but using the <b>imImage</b> structure to make the implementation easier.</p> + <p>For more IUP <a target="_blank" href="http://www.tecgraf.puc-rio.br/iup">http://www.tecgraf.puc-rio.br/iup</a> and + more CD <a target="_blank" href="http://www.tecgraf.puc-rio.br/cd">http://www.tecgraf.puc-rio.br/cd</a></p> + <p>You can view the source code here <a href="../download/im_view.c">im_view.c</a>, or download it with some makefiles + <a href="../download/im_view.zip">im_view.zip</a>.</p> + +<h3><code>glut_capture</code></h3> + + <p>This application uses GLUT and OpenGL to create a window with a canvas and draw the image into that canvas. But the + image is obtained from a capture device. The image can be processed before display and a sequence of captured images + can be saved in an AVI file during capture.</p> + <p>You can view the source code here: <a href="../download/glut_capture.c">glut_capture.c</a></p> + +<h3><code>iupglcap</code></h3> + + <p>This application uses IUP and OpenGL to create a window with two canvases and draw a video capture image into one + canvas. A processed image can be displayed in the second canvas. It can also process frames from a video file. It is + very usefull for Computer Vision courses..</p> + <p>You can download the source code and projects for Visual C++, Borland C++ Builder X and Dev-Cpp, here: + <a href="../download/iupglcap.zip">iupglcap.zip</a> You will need to download IUP, CD and IM libraries for the + compiler you use</p> + +<h3><code>IMLAB</code></h3> + + <p>If you want to see a more complex application with all the IM features explored the IMLAB is a complete example. It + displays each image in an individual image with zoom and pan capabilities. All the IM processing operations are + available together with some extra operations.</p> + <p>For more IMLAB go to <a href="http://www.tecgraf.puc-rio.br/~scuri/imlab"> + http://www.tecgraf.puc-rio.br/~scuri/imlab</a>.</p> + +<h3>Lua Samples</h3> + + <p>To retreive information from an image file:</p> + + <pre>require"imlua" +local ifile, error = im.FileOpen(file_name) +local format, compression, image_count = ifile:GetInfo() +local format_desc = im.FormatInfo(format) +for i = 1, image_count do + local width, height, color_mode, data_type, error = ifile:ReadImageInfo(i) +end +ifile:Close() </pre> + + <p>To edit pixels in an image and save the changes:</p> + + <pre>require"imlua" + +local image = im.FileImageLoad(filename) + +local r = image[0] +local g = image[1] +local b = image[2] + +for row = 0, image:Height() - 1, 10 do + for column = 0, image:Width() - 1, 10 do + r[row][column] = 0 + g[row][column] = 0 + b[row][column] = 0 + end +end + +image:Save("edit.bmp", "BMP")</pre> + + <p>To render noise:</p> + + <pre>require"imlua" +require"imlua_process" +local image = im.ImageCreate(500, 500, im.RGB, im.BYTE) +im.ProcessRenderRandomNoise(image) +image:Save("noise.tif", "TIFF") </pre> + + <p>To render using the CD library:</p> + + <pre>require"imlua" +require"cdlua" +require"imlua_cd" + +local image = im.ImageCreate(500, 500, im.RGB, im.BYTE) +local canvas = image:cdCreateCanvas() -- Creates a CD_IMAGERGB canvas + +canvas:Activate() +canvas:Clear() +canvas:Font("Times", cd.BOLD, 24) +canvas:Text(100, 100, "Test") +canvas:Line(0,0,100,100) +canvas:KillCanvas(canvas) + +image:Save("new.bmp", "BMP") </pre> + + <p>Check the file <a href="../download/samples_imlua5.tar.gz">samples_imlua5.tar.gz</a> + or <a href="../download/samples_imlua5.zip">samples_imlua5.zip</a> for several samples in Lua.
