[DUG] Image manipulation

[Conor Boyd]

I've used a mixture of GraphicEx and Graphics32 for a Delphi screensaver
I've written (http://gloss.ildica.com) which can handle most of those
formats, plus high-quality resampling/resizing and saving, so yeah, it's
possible.

IIRC I use GraphicEx for actually knowing how to load various image
types and then assign the image to a Graphics32 object for resampling
etc before saving.

http://www.graphics32.org/wiki/

It's open-source, works well for me under D2007, dunno about any later
versions.

If you have specific questions about using it for resampling, drop me a
line, and I'll look some code out.

Cheers,

C.

Hi

We want to do some basic image manipulation.  Specifically the following

1) open and dipslay Gif, jpg, and png image formats.
2) Resize the above file format
3) Save file back in resized format.

Does anyone have or recommend any code for doing such?

I have seen GraphixEx but it states it does not support saving of
images.

Cheers
Rob
