Convert webcam BMP to JPG

[vaibhavs]

Hi,

I am working on the Webcam snapshot AU3.

I am able to capture the photo in bmp.

Any way to convert it into JPG OR grab a picture in JPG format.

As a temporary solution I have found this free command line converter which converts it "bmptojpg.exe".

Please help!.

Thank you.

I guess the temporary option is the best one you have. Short of writing your own jpg to bmp conversion utility, which you don't want to do in autoit because of speed. Still you would have to either use other people's routines (check for open source image converter programs like there are for Linux if you want to do that) or write your own conversion routines which is hard work that's also already been done.

So if it's not your life mission to improve worldwide picture handling, I think you are way better off using something like your freeware app...

call a .dll

DllCall($dlldir & "\capture.dll", "int:cdecl", "capturewebcam", "str", $defaultdir & "\Full" & $pic & ".jpg", "int")

I recommend external commandline tol too. For example IrfanView.

Also Auto3Lib has capture functions also for JPEGs.

It also can convert to/from BMP, GIF, JPG, PNG and TIF.

Really powerfull library

Thanks for all the inputs.

To summarize, there are 3 options (a) Freeware tool (2) dll Call (3) AutoIT3 Library

I would like to avoid (1) Freeware Tool. The idea is to avoid having to carry an additional file.

Its best if 1 au3 file can handle it all.

C4NM7: can you help me with your dll call.

I am using this script: http://www.autoitscript.com/forum/index.ph...5&hl=webcam from rysiora.

Can you suggest where should I insert the line suggested by you.

I have installed the Library and will post the feedback on using the library.

Thank you.

Here's a little ditty that converts a BMP to JPG using Auto3Lib:

#include <A3LGDIPlus.au3>

Global $sImage, $hImage, $sCLSID

; Get BMP file to convert
$sImage = InputBox("BMP to JPG", "Enter File Name:", "C:\Image.bmp", "", 200, 130)
if @Error then Exit

; Initialize GDI+ library
_GDI_StartUp()

; Load image
$hImage = _GDI_LoadFromFile($sImage)

; Get JPEG encoder CLSID
$sCLSID = _GDI_GetEncoderClsID("JPG")

; Save image as JPG
_GDI_SaveToFile($hImage, "C:\Image.jpg", $sCLSID)

; Shut down GDI+ library
_GDI_ShutDown()
