It also has individual format functions such as IMGisPNG and IMGLoadPNGRW. That way I can keep up with IM and not have to wait for MacPorts to catch up. SDLSurface IMGLoad(const char file) More precisely, it loads ICO(Icon)/CUR(Cursor)/BMP, PNM (PPM/PGM/PBM), XPM, LBM(IFF ILBM), PCX, GIF, JPEG, PNG, TGA, TIFF, and XV thumbnail formats. My issue is that the portions that were transparent in the original image are colored in the clipped image. PNG Sort of like a texture unpacker, if you will. I import the image into resource file and then call it directly. I have tried setting various parts of the control to transparent but nothing seems to work. I have all my delegates installed by MacPorts, but I install IM manually to /usr/local/bin. Basically clip a rect area of the original and save the result as another. I can get this image to display properly in a picturebox or a Listview but in the DataGridView the image loses quality. This is working fine for all images that dont have transparency (all alpha values are 1.0). Alternatively you can use GDI+ but that’s pretty old technology and doesn’t work nearly as well. I already have all the code to load PNGs as OpenGL textures and render them. In order to simplify the code, I only support 32 pixel depth PNG images. But, it does not deal with transparent PNGs. Searching with the keyword 'PNG' in CodeProject, I found a demo named PNGView. You can use it to load a PNG image into your application. Some days ago, I needed a component to display a transparent PNG image in my code. Signature: f8a5c34c72b7e0291fe6f83ef6cac05b58a7b9e4c54684a1f173eefbfbee1c03Īs I said there have been changes in the last number of releases to the PNG format (still a work in progress to fix all the bugs), so as this works in 6.6.7.4, perhaps you should upgrade (though I don't know what version IM MacPorts is using). The Windows Imaging Component (WIC) is the primary API for native code that provides the ability to encode and decode various image formats.
