## dds-ktx: Portable single header DDS/KTX reader for C/C++ [@septag](https://twitter.com/septagh) - Parses from memory blob. No allocations - No dependencies - Single-header for easy integration - Overridable libc functions ### Build Example (ctexview) [**ctexview**](ctexview/ctexview.c) is a tiny ddx-ktx viewer that can be built on linux/mac and windows. To build it just compile the single file with your compiler. **Windows:** ``` cl ctexview.c /O2 ``` **Linuxx** ``` gcc ctexview.c -O2 -lGL -ldl -lX11 -lXi -lXcursor -lm -o ctexview ``` **MacOS** ``` clang -framework Foundation -framework CoreServices -framework CoreFoundation -O2 -fobjc-arc -x objective-c -fmodules -x objective-c ctexview.c -o ./ctexview ``` to view images just provide the image path as an argument: ``` ctexview [dds_or_ktx_image_file_path] ``` Used open-source libraries for app creation/graphics: [**Sokol**](https://github.com/floooh/sokol) **Keys:** - UP/DOWN: change current mipmap - Apostrophe: change text color - F: Next cube-map face - R: Toggle Red channel - G: Toggle Green channel - B: Toggle Blue channel - A: Toggle Alpha channel ### Usage In this example, a simple 2D texture is parsed and created using OpenGL ```c #define DDSKTX_IMPLEMENT #include "dds-ktx.h" int size; void* dds_data = load_file("test.dds", &size); assert(dds_data); ddsktx_texture_info tc = {0}; GLuint tex = 0; if (ddsktx_parse(&tc, dds_data, size, NULL)) { assert(tc.depth == 1); assert(!(tc.flags & STC_TEXTURE_FLAG_CUBEMAP)); assert(tc.num_layers == 1); //Create GPU texture from tc data glGenTextures(1, &tex); glActiveTexture(GL_TEXTURE0); glBindTexture(img->gl_target, tex); for (int mip = 0; mip < tc->num_mips; mip++) { ddsktx_sub_data sub_data; ddsktx_get_sub(&tc, &sub_data, dds_data, size, 0, 0, mip); // Fill/Set texture sub resource data (mips in this case) if (ddsktx_format_compressed(tc.format)) glCompressedTexImage2D(..); else glTexImage2D(..); } // Now we can delete file data free(dds_data); } ``` ### Links - [DdsKtxSharp](https://github.com/rds1***3/DdsKtxSharp): C# port of dds-ktx by [Roman Shapiro](https://github.com/rds1***3) ### TODO - Write KTX/DDS - Read KTX metadata. currently it just stores the offset/size to the metadata block ### Others - [stb_image](https://github.com/nothings/stb/blob/master/stb_image.h) - Single header library that loads images (.png, .jpg, .bmp, etc) - [bimg](https://github.com/bkaradzic/bimg) - Extensive C++ image library **NOTE**: Many parts of the code is taken from _bimg_ library.
