Directory & Image program..

Hi folks,

I have a lot of pictures (600+), and have to change the dimentions of them, from 1024*768 to 800*600, but I'm having some problems, and need some advise and/or help ;)

A console program is just fine, so I want it to check the folder the program is in, and then check for files with the extension .jpg/.bmp and then change the dimensions..

I've considered the header file dir.h and it's functions(not use the header file of course :p), BUT Microsoft Visual C++ 6 doesn't have the header file, is it possible to grab it from another compiler or does somebody have a better idea, to check the folder for files?? And if your suggesting dir.h and if your want, I would be happy if you would show me a little example.. I'm not that good at C++ yet :)

And on to my last problem, how do I change the image dimentions, I haven't found anything on changing that, so if would like some feedback on that to, if anybody knows how :D

All kind of help is appreciated very much :)

I don't think you can change the images resolution because I have been told that you can't even OPEN images in C++. Someone might suggest ios::bin, F-I/O but I think this would have to be done in windows.h.

I like Advanced Batch Converter for stuff like this. I once had to convert 770 png's to bmp's. This utility saved a ton of time.

I use this script for image resizing:

Code:

---

Const MAX_WIDTH  = 800
Const MAX_HEIGHT = 600

Set ImgIn = CreateObject("WIA.ImageFile")
Set IP    = CreateObject("WIA.ImageProcess")
Set FSO  = CreateObject("Scripting.FileSystemObject")

IP.Filters.Add IP.FilterInfos("Scale").FilterID
IP.Filters(1).Properties("MaximumWidth").Value = MAX_WIDTH
IP.Filters(1).Properties("MaximumHeight").Value = MAX_HEIGHT
IP.Filters(1).Properties("PreserveAspectRatio").Value = True

For i = 0 To (WScript.Arguments.Count - 1)

        ImgIn.LoadFile WScript.Arguments(i)

        If (ImgIn.Width > MAX_WIDTH Or ImgIn.Height > MAX_HEIGHT) Then
                IP.Apply(ImgIn).SaveFile FSO.GetParentFolderName(WScript.Arguments(i)) & "\" & _
                    "resize_" & FSO.GetFileName(WScript.Arguments(i))
        Else
                ImgIn.SaveFile FSO.GetParentFolderName(WScript.Arguments(i)) & "\" & _
                    "resize_" & FSO.GetFileName(WScript.Arguments(i))
        End If
Next

You'll need Windows XP and the free Windows® Image Acquisition Automation Library.
Save as a text file with .vbs as the file extension.
Drag desired files onto it.
It will handle BMP, JPEG, TIFF, GIF and PNG.

For use of WIA in C++, see this WIA sample.

Thx, I'll take a look of what you've posted :)
