freeimage

问题 I have a list of .png (PIL) images I want to string together into an animated gif To do this, I am currently using the imageio library However, I cannot find a way to do this to produce good quality gifs As far as I know, there are two types of settings I can change. The imageio.imread() settings for reading .pngs, and the imageio.mimwrite() settings for writing gifs. According to imageio.help() , imageio.imread() has one read paramter only for PNG-PIL , ignoregamma which takes a boolean.

问题 I was advised by some of you not to long ago to use FreeImage as a library for image processing in C++. I now have some trouble in getting the library to work (still relatively new here). I've tried loading the various vcxproj and sln tiles and they gave me a blank project. Since there isn't any installation instructions provided for that, I gave up on making it a visual studio solution. I next tried the old-fashion way of compiling the source code using the Makefile and then adding

问题 I'm trying to load an image because I have to apply an algorithm on it. If I load an 8 bit-per-channel image there are no problems, but if I load a 16bpc image then it get "ruined". Unfortunatly, since I don't have enough reputation I can't uplad images. Those are the links to them: Either the source and the 8bpc processing result http://postimg.org/image/gc0zf2lp5/ ..result if I process the same image saved as 16bpc http://postimg.org/image/5nnwee7df/ And this is the code: FreeImage

问题 I need to exchange data between FreeImage (FIBITMAP) and OpenCV format (IplImage and/or Mat). I'm fine with getting data from a FIBITMAP into an IplImage or Mat since FreeImage gives you a function FreeImage_GetScanLine which you can set the OPenCV imageData ptr equal to. However, I'm stuck on how to do the reverse, i.e. once I have an OpenCV image, how do I get its data into a FreeImage image? 回答1: You have to be a little careful just copying the data pointer, a lot of image formats have

问题 I've downloaded the latest compiled version of FreeImage, then build FreeImageNet wrapper. Put FreeImage.dll and FreeImageNet.dll on the same folder as my executable (the sample code). But everytime I run it, it says freeimage.dll is missing. I modified the code on FreeImageWrapper.cs and remove the exception handler public static bool IsAvailable() { /*try {*/ // Call a static fast executing function Version nativeVersion = new Version(GetVersion()); Version wrapperVersion =

问题 I tried this code with FreeImage to load my tif, and i get no error, but also no output. It works just fine if the input is a jpg. My tiff input is 16-bit greyscale. public void OpenRotateSave() { // load image, 16-bit tif FIBITMAP dib = FreeImage.Load(FREE_IMAGE_FORMAT.FIF_TIFF, "Mytif.tif",FREE_IMAGE_LOAD_FLAGS.DEFAULT); // save image FreeImage.SaveEx(dib, "MyTifOut.jpg"); // unload bitmap FreeImage.UnloadEx(ref dib); } I tried to Load without the modifiers, using just the filename, the

问题 I am currently trying to create a multiplatform application (targets are Windows and Android via ndk). So the problem is in textures (as in topic of this post). It works great on windows, but in Android FreeImage_GetFileType returns FIF_UNKNOWN , despite the fact that I can read part of .png file manually from same file path (only PNG file magic, beceause then it contains some null bytes). I use them this way (only part connected to this issue): Texture::Texture(std::string fpath) :Resource

问题 I'm having a lot of trouble linking my project with FreeImage library with VSE 2013 I've followed this answer for VS2010 to no avail: Linking FreeImage as a static library in VS2010? I am getting LNK2019 errors when calling FreeImage functions. I've linked the library just as I would any library. Below are the following steps I made: Download FreeImage Source. Open the 2008 Solution (converted to 2013) and changed Code Generation to /MDd for all projects Attempted to build project but for

问题 I'm learning OpenGL in C++ using NeHe tutorials, but I'm trying to do them with FreeImage library, instead of Glaux or SOIL. The good point I see in using FreeImage is thar it's last update was in October last year, while SOIL hasn't been updated in 5 years. The problem I have is that I'm not able to load textures correctly. Here is my code: static GLuint texture = 0; if (texture == 0) { FIBITMAP* bitmap = FreeImage_Load( FreeImage_GetFileType("textures/test/nehe_06.png", 0), "textures/test
