need help on image resize (don't crop, resize and keep ratio)

[Thomymaster]

Hi

 

I have a problem and i don't know how to solve it

 

I have lots of images (approx. 2000) which should be resized as follows (the aspect ratio should be kept at all times!):

-get the pixelsize of the longest side (width or height)

1. if the width is above 1000, resize it to 1000 (the height will be scaled accordingly without affecting the ratio)

or

2. if the height is above 1000, resize it to 1000 (the width will be scaled accordingly without affecting the ratio)

Currently i use a call to IrfanView for this, but its quite slow.

"i_view32.exe O:\pics\0001.jpg /resize=(1050,0) /aspectratio /resample /convert=O:\pics\0001.jpg

Is there a way to handle this using GDIPlus?

 

Cheers,

Thomy
