[Xweb-developers] preserve ratio in imageCopy

[Ralf P. <ra...@pu...>]

Hi,

creating thumbnails width the imageCopy-docstyle is a cool feature,
which could save me a lot of time. But for my galleries i need to
scale images with (max)height and (max)width where the width/height-
ratio should be kept:

<documentStyle type="image.thumb">
   <imageCopy width="135" height="135"/>
</documentStyle>

The code for scaling would be the following (ImageCopyDocType.java:113):

} else if (this.width != -1 && this.height != -1) {
     lastWidth = oldWidth;
     lastHeight = oldHeight;
     if (lastWidth > width) {
         lastHeight = (lastHeight * width) / lastWidth;
         lastWidth = width;
     }
     if (lastHeight > height) {
         lastWidth = (lastWidth * height) / lastHeight;
         lastHeight = height;
     }
}

Would iit be possible, to integrate this feature into XWeb?
Another possible solution would be adding new maxHeight and maxWidth
attributes to the imageCopy tag.

Ralf
