How to display an in-memory jpeg (w/header) using jpeglib on Palm

Dear all, I am currently trying out jpeglib on decoding jpeg data on Palm, does any one know which function call I'll need to pass a chuck of memory (jpeg header + data) to jpeglib for decoding? I'd found the one reading from VFS, but my data is already loaded onto Palm memory (just like read

Re: sprintf override by StrPrintF. Why?

Give this a try. One caveat--it doesn't round up the least significant digit. Also, you can probably get rid of the overflow stuff at the end. Thanks Steve, I'm still searching for a "easier" solution, before I'll give your code a try, as I have somehow a problem in reimplementing a basic funtion

Re: How to display an in-memory jpeg (w/header) using jpeglib on Palm

I've been finding a free jpeg decoding library for several weeks but just jpeglib is available. Of course, it is ideal to get the library from Konstantin (http://www.absoluteword.com/jpglib/). That is wonderful with high speed decoding, However, if speed is not a concern and time is available to s

Re: Think first, then write

So another question for the experts: I've found out why sprintf() shows weird behaviour, and that is a "#define sprintf StrPrintF" in /Core/System/Unix/unix_stdio.h. So I never actually call the "real" sprintf(). Okay, sorry! I've found out that my previous post is false. I have not included any

Re: sprintf override by StrPrintF. Why?

The OS doesn't support sprintf so you must use StrPrintF. I assume the #define is to force you to use the supported routine. In fact, the Palm OS does not support most standard C API calls, so use the Palm version of them. - Original Message - From: "Jan Bandouch" <[EMAIL PROTECTED]> Ne
