How can i create .jpg file programatically

PankajB

Hi there. I want to create jpg file programmatically. Lets say I have some text "Hello", Now I want to create a jpg file that contains this text. Thanks PanB

So have you bothered to study the JPG file format?

Two steps: 1. Draw your text to a bitmap. 2. Compress it to JPEG.

Not yet. I was mainly looking for some sample code that can do the trick. Can you please provide some pointers to do the same?

I want to do this programatically. I think you have suggested using some tool may be mspaint. If you are talking about through the cose itself, then please provide more details in raegrd to the sugegsted steps. Thanks.

Have you searched the internet and CP? Usually, nobody feels like offering any help to people who are not willing to help themselves. Not to mention you're asking for "the code" to do something that's extremely trivial. Like I said, in my other reply to you, there are two steps to it. Go ahead, give it a try and come back with a specific question if at all.

I knew you wanted to do it programmatically. Have a look at Drawing lines, shapes, or text on bitmaps[^] and then you'll be left with compressing a bitmap to JPEG. A search must bring up an example, if you ask me.

Have a look at the jpeglib[^] stuff. IMO, it's not an easy task if you want to do it completely manual. Like other said, create an in-memory bitmap and save-as jpg with a known API like CImage or something similar.

If you like to see more info about jpg format see CXImage article on the codeproject it has helpful info for you.
