[vox-tech] Success with fltk and SDL_image

[Jan W]

Hi all:

Just a question:

Has anyone used SDL_image to do scaling and rotation?  If so, is there anything
that I could use to do basic image manipulations?  I am looking for code
examples/basic theories so that I can start off down a (more or less)
reasonable path...

I had an application that used fltk_images and libtiff to open images.  It was
large, unwieldy, and unfortunately, a bit slow.  SDL_image was a bit faster b/c
(at least, this is what I _think_... I'm still such a noob) of the way that I
allocated the buffer for the image:
(img_w)*(img_h)*(sizeof(current_color_depth)).  So if you had a 24bit depth
color display, and a B/W image, I allocate enough space for a 24bit color...
not the right thing...  It would have been tough to recode (for some reason
that I can't recall), so I decided to try something different...  

Now, SDL does the work for me, and just leaves me with a surface... awesome.

So if anyone has any hints/tips/tricks/caveats on SDL surface manipulation, I
would love any tidbits that might float my way...  and if anyone is interested
in seeing my code (yea, I have the coding style of an 8 year old), just don't
laugh when you do.... (write me off list and I'll send a copy)

--thanks
