Notes
As is obvious, the focus of this release has been Window Level & Window Width manipulations since this was a frequently asked for feature.
For performance & bandwidth reasons we had to make the following compromises.
- Oviyam retrieves a new image only on mouse button up, based on the delta of mouse movement, not on mouse move as in Xero. In plain words, Oviyam fetches a new JPEG image with the changed WL/WW only after the mouse button is released, based on the distance the mouse button has been clicked and moved. Xero continuously fetches new JPEG images as the mouse is clicked and moved over the image.
- DICOM images larger than 1024 pixels in width are proportionately scaled down to 1024 pixel width.
At present we're using the standard WADO service of dcm4chee. Bill has implemented a faster and more optimized version called WADO2 in his Xero project which we would like to move to in future.
Thanks to Justin who contributed code from one of his projects for WL/WW presets.
