Hey all,<br>
<br>
I've got new interesting findings :-)<br>
<ul>
<li>The error of the height of the image does<u> not appear at all</u>
when I zoom <b>three </b>times.</li>
<li> When I zoom <b>twice</b>, the error appears<u> only in the
middle </u>of the image, but not when I see the background of
the Map! I cannot say exactly,... </li>
<li> But when I does not zoom or<i><b> only once...or four times
or more</b></i>... the image is<u> not resized </u>I
think...it is the original ratio....</li>
</ul>
I have got some screenshots, so that you might understand it better
:)<br>
<br>
Perhaps, it is a graphical bug? I don't know...perhaps, somebody's
got an idea? would be cool to be fixed!<br>
<br>
<br>
Regards,<br>
<br>
Marcel<br>

Thanks for the explanation.<br>
<br>
As I said, the ImageExt values are correct...(y is calculated by
_y + _h, I think) .....I have debugged the data flow and
everything is understandable up to this function (and afterwards.
What the function is doing might be clear, and even the values of
the viewRect, too,...after your little explanation, what should be
self-evident :-) <br>
<br>
However, the final lower/left edge of the picture is not shown at
53.475096504° where it should be, but somewhere at 53.464...and I
cannot find the code where this is calculated...(but better to say
that I have given up because of so many steps...)<br>
<br>
Best regards,<br>

<div>that method computes the extent of the view when you add
the first layer. The app knows the size of the screen and
the extent of the layer, and their ratios are different, so
you have to do a simple computation to find out the extent
of the new view.</div>
<div> </div>
<div>Maybe you have misunderstood the extent of a layer and
the extent of the view?</div>
<div> </div>
<div>When you add the first layer, the extent of the view is
the smallest rectangle which contains the extent of the
layer and, at the same time, respects the width/height ratio
of the screen, of course.</div>

<div>well, I think the main problem of understanding is in
function MapContext.<b>getExtentFromFullExtentAndImageSize</b>()
... I think the new height etc are calculated there? <br>

<blockquote>Hello, <br>
<br>
I have tried to load a raster image (had to try jpg, because
*.png did not even load), but I am getting a wrong position
of the extent. Anybody got the same error? <br>
<br>
I have tried the debug mode, but there are too many
functions to catch on. Perhaps anybody can help? <br>
<br>
Somewhere the map origin is changed from the upper edge to
the lower edge, that far I could follow, but then the image
extent (height) and the origin coords (of Y) has been
changed. Why? it seems to be very hard to understand the
whole way of building the image at the right place. <br>
<br>
However, in attachment the original rectangle and the
changed one are shown with their values while debugging... <br>
<br>
The lower edge of the final image is positioned between
those Y values (@ 53.464) but it needs to be positioned at
53.475.... <br>
<br>
what is getRasterTansformation() actually doing? <br>
<br>
<br>
Thanks in advance, if anybody can help. However, that issue
should be fixed, I think. The import of PNG is not even
possible, as I mentioned before.. <br>
<br>
Regards <br>
