GdiPlus Library

[JohnF]

Here's a tip when using images with GDI+.

GDI+ Bitmaps and GDI+ Images are interchangeable so if you want to save a HBITMAP to disk as a JPG use something like the following.

(EDIT: By Bitmaps and Images are interchangeable I should qualify that. Interchangeable for API's I have tried.)

Use GpBitmap_FromHBITMAP(HBITMAP hbm, HPALETTE hpal) to convert your HBITMAP to a GDI+ Bitmap then use one of the routines linked to above on my web site. Parameter hpal is NULL for a Device Independent bitmap.

You will need to cast the GDI+ Bitmap to GDI+ Image

(GP_IMAGE*)

Hallo,

I am playing a little with the projects in GdiPlus.zip

The first I looked at was GdiPlusDecoders.

Can you tell me what the file GdiplusImageCodec.c is for and why not call the gdiPlus functions directly?

It's the way M.S. arranged things.

It's up to you if you want to call the functions directly - I just translated the CPP files into C.
