The user interface will be built entirely with AVD and the coding will be written in C++. It will need to carry out the following operations: Image loading 1) Detect File Type 2) How to open a requester, listing filtered by support image types above 3) Load PNGs, GIFs or JPG... WebP would be nice also. 4) Load image into an object 5) Scale image/object XML Handling 1) Read a plain text file/xml file 2) Parse the XML file into an array or structure so I can... a) Address tag data b) Manipulate and add new tag data into the structure 3) Write the plain text file/xml file back to disk. Nb: Projects will be created in PROGDIR: So a nice example of how to open/close files would be useful as well. GUI I guess AVD will format the code so I can act on user interaction. Eg. Able to read a slider to get the value, set minimum and maximum of a slider in C++ - just one example. Upload Does AmigaOS4 come with a Curl command as standard? Curl method: 1) How to call an external command using C++? 2) Act on its result If not implement this myself, which will require routines for: 1) Check an internet connection is available 2) Reach an FTP Site 3) Upload a file 4) Provide a progress bar 5) Check file has finished uploading 6) Error handling
