new altResizeImage Library available

[Chipp Walters]

I've recently finished a new library control which allows you to resize 
and save images in different file formats. It's all in transcript and 
can be found at the bottom of page:

http://www.altuit.com/webs/altuit2/RunRev/Downloads.htm

It uses the little known bilinear interpolation algorithm built into 
RunRev-- property called 'resizeQuality', to create a very nice resized 
image.

You could use this control for instance to build a program that 
automatically made thumbnail files for a folder full of images, or to 
convert PNG's into JPEGS. I've tested in only on WinXP for now. If you 
find a problem, please email me offlist.

best,

altResizeImgLib
by Chipp Walters, Altuit, inc.

This library allows you to resize and save an image with the 'best' 
resizeQuality of the engine while maintaining the aspect ratio. It can 
save in PNG, JPEG or GIF formats (if you have purchased the GIF unlock 
code from RR).

This DEMO stack
Press the Resize Image button and you are prompted for an image to open. 
Then you are asked for a filename to save as. Next, the altResizeImage 
command is called with the parameters specified by Maximum 
Height/Maximum Width and the pixel value.

If you set the control to Maximize Height, then the image height will be 
set to the height value specified with the width being whatever it needs 
to be to maintain proportions. If you set the control to Maximize Width, 
then the image width will be set to the width value specified with the 
height being whatever it needs to be to maintain proportions.

You can press the Open Viewer button to browse for and view the newly 
resized image.

How to install
Make the stack "altResizeImg" as a substack of your main stack.

Then use the commands:

start using stack "altResizeImgLib"
altResizeImage tFilePath,tFilePathToSave,tSize,tMode,tJpgQual
stop using stack "altResizeImgLib"

Where:
tFilePath IS THE ORIGINATING IMAGE FILEPATH

tFilePathToSave IS THE DESTINATION FILEPATH
NOTE: THIS HANDLER WILL LOOK AT THE EXTENSION OF THE FILE IN 
tFilePathToSave TO DETERMINE WHAT FILE TYPE TO SAVE AS. IF NO EXTENSION 
THEN DEFAULT IS "JPEG"

tSize IS THE MAXWIDTH OR MAXHEIGHT IN PIXELS. ALL IMAGES ARE RESIZED 
PROPORTIONALLY

tMode IS EITHER "MaxHeight" or "MaxWidth" AND TELL THE HANDLER WHICH ONE 
TO OPTIMIZE

tJpgQual IS OPTIONAL AND TELLS WHAT JPEGQUALITY TO SAVE AS. DEFAULT IS 90
