Hi..!
I need to save immage file types like original size and also like Thumb...!
I need to Reduce it about to 20% of original size.
I use this way to easy show the pic in form, and if i need to enlarge i
use the original size.
All is needed in a Immage Database sistem.....!

Alessandro,

Why would you want to do all of that? You can show samples
any size you want directly from the original, without
saving thumbs... just add an Image box on your form and
set the Size Mode in properties to either Zoom or Stretch
(try both to see what they do) and you're done!

Yes, right, but i use very Hight_Resolution image, so using
wideOriginal i need to load some Mb in Jpeg, and you know
that Access transform "ON THE FLY" in bmp format....!
So the program is very slow to movenext record.....!
The only way to resolve this truble is save the same Picture
in Thumb format and use the Thumb to move trought the
recordset...., when i need to enlarge for Zoom effect, i load
the Hight_res.

Have you any more idea....?

Thanks.
@Alex.
 
Loading the full res image will take longer to read from disk, much longer to decode, and give poor display
quality (compared to a thumbnail resampled to the correct resolution). Furthermore, since the Access Image
Control can cause the application to crash if records are scrolled while the control is still decoding,
reducing this time may be desirable when using that control.

I can't think of any good reason to display the full res image as a thumbnail, in much the same way as
it's such bad practice to do so on web pages (unless you consider "it's easy" as a good reason).

Right.., i'm to obtein WebPages effect..... to easy show my pic with no
crash problem.
I need a way to do this.
I look in http://www.ammara.com/ and it's OK OCX, but i prefer do it OCX
Free.
My Application will be a free application, i'll send it in Access Italian
SITE, so use
OCX for many people(me to) is not good idea.

I try to use GDI but i'm not very hard experience with API, so........!

Thanks.
