Lararus 0.9.24 is finally out so the new RawImage API is now used as default by Imaging.

I don't know how to detect the lazarus version at compile time, but some place I was reading about performing an {$IFDEF ProcName} or something similar.  I'll take a look around and see if I can find it.

I noticed the thread after you pointed it out, but the title threw me and didn't notice it when I was looking for a fix.

This Lazarus problem was already reported, but thanks anyway:

There should be comments how to get it working with new Laz
in SVN code.

I just hope they release Laz 0.9.24 soon. Until that time I have to
keep the old RawImage code active because I think that most people
use Laz 0.9.22. Or do you happen to know a way how to detect
Laz version during compile time? This would help a lot.

I just downloaded the latest snapshot of Lazarus only to find that it completely breaks when you try and install Vampyre.  The problem is that they (unannounced to anyone) have deprecated and removed CreateBitmapFromRawImage and a few others.

The fix is to open ImagingComponents and edit the following lines:
Change
Code Select
if CreateBitmapFromRawImage(RawImage, ImgHandle, ImgMaskHandle, False) then
to
Code Select
if RawImage_CreateBitmaps(RawImage, ImgHandle, ImgMaskHandle, false) then
and Change
Code Select
if GetBitmapRawImageDescription(Bitmap.Handle, @RawImage.Description) then
to
Code Select
if RawImage_DescriptionFromBitmap(Bitmap.Handle, RawImage.Description) then
and Change
Code Select
if GetRawImageFromBitmap(Bitmap.Handle, 0, Classes.Rect(0, 0, Data.Width, Data.Height), RawImage) then
to
Code Select
if RawImage_FromBitmap(RawImage, Bitmap.Handle, 0, Classes.Rect(0, 0, Data.Width, Data.Height)) then
and FINALLY Change
Code Select
FreeRawImageData(@RawImage);
to
Code Select
RawImage.FreeData;

Just thought others might want to know about this so that the next time you update you don't have to do the leg work yourself :).
