Mylistbox is defined earlier in the script and will have a file name in the format of
pic.jpg

I want to convert it to bmp and retain the original file name with the extension bmp. As in pic.bmp

I tried this
Code:
ConvertImage(mylistbox,"mylistbox.bmp")
this gave my converted picture the name
mylistbox.bmp


Code:
ConvertImage(MyListbox,MyListbox . ".bmp")
this gave my converted picture the name
pic.jpg.bmp


Code:
ConvertImage(mylistbox . ".jpg",mylistbox . ".bmp")
this gave my converted picture the name
pic.jpg

I was certain I could remove the extension from mylistbox because I read somewhere that convertimage() did not care what the original extension was.

I was hoping to avoid that.

thanks

lol, everyones disregarded that this function is old and rubbish :wink:

The gdi+ library will do this much better

Code:
#Include Gdip.ahk

pToken := Gdip_Startup()
pBitmap := Gdip_CreateBitmapFromFile("file.jpg")
Gdip_SaveBitmapToFile(pBitmap, "file.bmp")
Gdip_DisposeImage(pBitmap)
Gdip_Shutdown(pToken)


I know its longer, but that could all be wrapped into one function:

Code:
ConvertImage(sInput, sOutput)
{
   pBitmap := Gdip_CreateBitmapFromFile(sInput)
   Gdip_SaveBitmapToFile(pBitmap, sOutput)
   Gdip_DisposeImage(pBitmap)
}


Use that instead!

Thanks

Is it possible to convert an input image from memory instead of from file?

Is there a way to get a hold of this function because the link in the OP doesn't work?

A good idea would be a similar function for bitmaps stored in memory. For example using your GDI+ library. Not a convert image, but a simple resize.

Maybe there is one already, but I've not had much time to look. Then you could do:

Code:
pBitmap := ConvertImage(pBitmap, 200, 100)


See what I mean? If there is one already, I apologize.
