Hello, I was wondering if any of you guys out there knew how to make a simple graphics program. Nothing advanced like a drawing program, just a program that will allow me to convert popular graphics types like .gif/.jpg/.bmp/etc. and optimize them and save them. Thanks.
Sorry Dear friend,
I have tried many ways to do the Graphic Converting. But in VB, I can say this is VERY VERY Hard. almost impossible, so forget it.
Thanks guys.
If it is hard in VB, it is either hard in ANY language, or you are doing something wrong. From what I have heard, jpg conversions are hard, while there are easier formats out there. All you need to know is Binary file IO, which anyone can pick up in a few hours, and the file format. At that point, it is just implementing read/write algorithms. Simply read the image data into an intermediary format (stored in memory), that you can pass to a function that will write into the specified format.
Z.
But when you do this, all advantages of VB over other languages like C/C++ are lost. The whole UI of such an app would be a dialog, which is easy even in C. Compression algorithms like the one for JPEG would be a lot faster then (but in reality, it doesn't matter because File I/O is always slow).
Problem with VB in this case is that it is very hard to use third person libraries such as Intel's JPEG library (very fast, especially on a Pentium :D)
