Save hbitmap to jpg file

Uncover what the passengers are hiding and write the grisly conclusion of its final hours in an open-ended, player-driven adventure. Dave Hunt Adam Hamilton I found this link with a jpeg library for you Click Me!!! It wasn't meant to answer his question. It was meant to get an idea of where the poster is coming from.

If it was just a one-shot deal where he's got some BMPs and wanted to save them a JPGs, then my suggestion isn't all that bad. If it's more extensive, then my follow-up response would have directed him to other sources. Well, converting a BMP into jpeg manually wouldn't bother me, but I am not making the program for myself. I want it to save the bitmap that it works on as a JPEG for convenience reasons. Quote: Click Me!!!

I am having a real hard time trying to get just the bits I need from it. You should just need the headers and. You'll need jpeg There are examples for using the API in libjpeg.

What error are you getting.

Just saying you are getting an error doesn't help and on my end at least that code works. Wednesday, January 27, PM. Thursday, January 28, AM. Thursday, January 28, PM. Thank you very much. Wednesday, September 29, PM. Try This code.

Compressed data handling source and destination managers The JPEG compression library sends its compressed data to a "destination manager" module. The default destination manager just writes the data to a stdio stream, but you can provide your own manager to do something else.

Similarly, the decompression library calls a "source manager" to obtain the compressed data; you can provide your own source manager if you want the data to come from somewhere other than a stdio stream. In both cases, compressed data is processed a bufferload at a time: the destination or source manager provides a work buffer, and the library invokes the manager only when the buffer is filled or emptied.

You could define a one-character buffer to force the manager to be invoked for each byte, but that would be rather inefficient. The buffer's size and location are controlled by the manager, not by the library. For example, if you desired to decompress a JPEG datastream that was all in memory, you could just make the buffer pointer and length point to the original data in memory. Then the buffer-reload procedure would be invoked only if the decompressor ran off the end of the datastream, which would indicate an erroneous datastream.

On a machine where char is not exactly 8 bits wide, you must define JOCTET as a wider data type and then modify the data source and destination modules to transcribe the work arrays into 8-bit units on external storage.

The manager is expected to remember the buffer's starting address and total size in private fields not visible to the library. In most applications, this must flush any data remaining in the buffer. If you want the destination manager to be cleaned up during an abort, you must do it yourself. March 5th, , PM 6. I'll see what I can do, I don't work with this type of code alot. To start off with, I didn't have the header files, so I downloaded them, but now have a bunch of linker errors.

What library do I have to add to my project? Does every computer have this library? March 6th, , AM 7. Join Date Nov Posts March 6th, , AM 8. Ovidiu "When in Rome, do as Romans do. March 6th, , PM 9.
