Hi Geoff,

Thank you for the improvement, I'll include 1.85 for OpenJUMP 1.6 release.


On another topic, I don't know if you followed the topic on SVG export.

Andrei Nacu made some tests on svg printing with OpenJUMP Core and withJump printer

There were problems with the output resolution and with the output scale
I could solve some problems for OpenJUMP core svg export
(I temporarily change the output resolution and the decimation parameter) :

According to Andrei, scale problem also exist in JumpPrinter (and maybethe resolution problem too) :

Dear All

Re: Printer Plugin

I have found the problem with the colour patches in the Layer Legendwhen colour themeing is used, but not the reasons why it has occurred.

I have posted an updated JumpPrinter.jar that will now always solidfill the colour patches in the LayerLegend. I am not sure why I hadorginally allowed for a pattern fill, as if themeing is used then thefill might be expected to be a solid fill.

For some reason (which I don't fully understand) the"themeStyle.getAttributeValueToBasicStyleMap();" seems to return ahatched pattern (WKT type) from a layer with a themeing style. I amnot sure whether this has occurred with a recent release (I amcurrently using 1.5.2) or whether it has always been a bug and justnot reported/identified. It also occurs after the Properties dialoghas been used for the first time.


Please report any other bugs.

Hello Michael,

Hi,

Hello Emil,

You can edit the minimum and maximum values and the labels in the
table of color theming dialog. After that You choose the right
mouse click on the layer in the right layer panel, choose copy
style and than select the other layer which You want to style in
the same scheme and make again a right mouse click on the layer
and choose paste style. When You always work in project You do
not loose Your style and You can copy and paste styles between
different openend projects.

Good tip Arnd,

As I just realized in Your attached screenshot You also have a
problem with partially hachured legend. I often have the same
problem and I found no workaround for it. May be some others have
a solution.

Can you clarify what the problem exactly is, please,

Regards,

Michaël

Kindly regards
Arnd

*Betreff:* [JPP-Devel] Colourtheming problems
Dear all,

I'm doing a study of the geographic distribution of tuberculosis
in Indonesia, using OpenJump.

I've encountered a problem, and if you would have time to help it
would be greatly appreciated.

I want to make two maps with the case notification rate, from
year 2007 and 2011 to compare the progress.

However, when I do the colour theming, I can't find a way to set
my own values. To be able to get a clear impression of any
change, there should be the same colourtheming scale for both
years, otherwise it's not possible to interpret them by colour.
For instance, setting the colourtheming interval to 0-100,
101-200, 201-300 etc in both maps. With the methods I've tried,
for instance equal interval and Jenks optimal, the data is
divided so the maps looks almost exactly the same, even though
there are some substantial differences. I've attached two drafts
so you'll get an idea. As you can see they look very similar at
first glance, but when you look at the legend you can tell the
difference in colourtheming.

Is it a way to work that out, to set the colourtheming interval?

Kind regards

Emil Fast
