I cut the black marge with Photoshop and when I put the file on the Internet
it says me that the area is more than 1/25 of the main image area.
What's the problem? Must I reduce the resolution of the image with Photoshop
to arrive at the same resolution of the main image?
That's the code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55"
Thanks,
Oleguer

Note that I personally favour BMP for output. The main reason is that images
of this size take ages to save in PNG in the image editing program I'm using
(and in the other I tested), so working on large PNG files can be really
painful. Saving and loading BMPs is extremely fast in comparison.
Also, while partial BMP files seem to be fool-proof, partial PNG files can
be a problem (my editor don't open them for instance), so I don't think it's
advisable to use PNG as an output format in this case (converting the BMP to
PNG after the render is advisable). Of course, these PNG-related issues may
not exist with the image editor Oleguer is using, so your mileage may
vary...

Please carefully read the rules and check out and also carefully read the
notes how to compute the detail image area on the sample page at
<http://www.povcomp.com/samples/>. These two pages explain in great detail
how the detail image area is computed and what the requirements are.
The message you get tells you that the area you entered as the area of the
detail image within the main image exceeds 1/25 of the total area of the
main image. The area of the detail image is what you entered on the upload
page of the detail image, in pixel coordinates within the main image. This
has nothing to do with the size in pixels of the detail image.

But, if I put this code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55"
For the detail image 1 it tells me that "Size: 2877x957, Main Area: 0/0 to
0/0 461 KB "
What is wrong? Is my code wrong? I must select an smoller space?
Yes Gilles, I get a BMP and then I cut it with Potoshop, no problem with the
size. The next time I will render it directly on PNG and it will be smoller
and easier to work with it.
Thank you very much,
Oleguer

If that's indeed your parameters then it's wrong since you didn't provide a
+EC value. The detail view goes up to the right border so it's larger than
the 1/25 required in this case. Just check the size of the image you
submitted. It shouldn't be larger than 1280 x 960 in your case. If it is,
cut some margins it until it fits. I don't know about Photoshop, but the
editor I use has a feature that lets you cut out a precise area.

Ok, now I rendered with this code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55
+EC0.75" and the image is very big, I cut all the black marge and I only
have my portion of the image and when I upload this portion of the image it
gives me the same advertisment.
I think the problem is I did the portion of the image very big, is it right?
Thanks,
Oleguer

Oh, yes, I have to reduce the portion of the image to 960x1800, like the
main image. Is it?

What is the size, in pixels, of the image you're trying to send?

That's it: Size: 2877x957, Main Area: 0/0 to0/0 461 KB.

Well, as you can see it's too big as you made a mistake while passing the
partial render parameters. Remove parts of it until it fits in 1280 x 960
(or 1280 x 957).
