I'll investigate the UpdateData() idea.
See my last post to Mark with regard to more explanation on the problem.
Thanks!

Is there any simple way of reading JPEG and TIFF images without using all those big libraries?? My images are no more than 512x512, so the images are pretty small. I would like to know a easy way to read the height, width and pixel data of the image nothing more than that.
Any suggestions??
-thanks

Read the documentation on the File Formats and implement your own code to obtain the width and height and pixel data, if you call that "simple"? Or were you looking for the "Magic" solution?

I know from experience how many trips to McD's THAT project takes!

Why didn't you just use the "magic" solution? You could call yourself "The Great Salsbery"

You mean such like SetDIBitsToDevice?

Now why would you give away secrets like that on a public forum like this??

Would you prefer to answer questions in Mark's forum all alone?

Nah. It's just those magic solutions are scary...luckily I have the worm's wart, frog's breath,
and chicken feet nearby...

Last time I checked that was part of big library.

I would say the least amount of work and impact on your projects would be to use GDI+.
It comes with recent Windows versions and you can load images with a couple lines of code.

I read your message as decoding an image format into raw RGB values. If you for example take uncompressed TIFF files (see Google), it's a rather simple parsing of file header and reading binary data. For a more complex format like JPEG you would need to implement the complete algorithm for decompressing/transforming... or just use a free library.
Btw, Windows GDI allows you to draw JPEG/PNG image data without manual decoding, see SetDIBitsToDevice. Easy peasy.
Hope it helps.

GDI+ is the easiest option here. But, the point of libraries is to MAKE it easy, by stopping you from having to write the code yourself.

You're going to need a big library if you want to draw TIFF images because there is no code built into MFC or Windows to load TIFF images. I recommend FreeImage. It has all the best features, and even works on mobile devices. You can (with a little programming ability) even reduce the "big library" down to the absolute minimum that only supports the image types you intend to load.

Is there a C/C++ function that will tell how many bytes are valid in a buffer?
|
|
|
|
|
not in general.
if it was allocated with GlobalAlloc/HeapAlloc, you can get the size with GlobalSize/HeapSize.

Of course not. That can only be determined by the code that placed those bytes in the buffer to begin with.
