Looks like smoothing is not working or something is missing in the code. Maybe Matrix should have something more?</p> <p>Original image:</p> <p><a href="http://imageshack.us/a/img28/4784/dc7f2ec4b0f3323cdc4e01e.jpg" rel="nofollow">http://imageshack.us/a/img28/4784/dc7f2ec4b0f3323cdc4e01e.jpg</a></p> <p>and it's result:</p> <p><a href="http://imageshack.us/a/img855/4784/dc7f2ec4b0f3323cdc4e01e.jpg" rel="nofollow">http://imageshack.us/a/img855/4784/dc7f2ec4b0f3323cdc4e01e.jpg</a></p> <p>I can link a bunch of others images. Some strange pixel disposition exist. Can it be fixed somehow?</p> <p>I have tested jpeg quality 100% and stage.quality='best', but none of them give the required quality outcome.</p>

    2. COIt's working fine for me, and your code seems ok... don't really know what to tell you (as this shouldn't be affected by platforms or any other scenarios or external configurations). Are you sure you are adding the correct BitmapData to stage?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
