Separation Space
Hallo there,
I am trying to define a Separation color space but get the following
error message if I try to run the program posted beneath. The error
seems to be quite local; coming only from the setAlternateColorSpace.
What is going on here? I am using
org.apache.pdfbox:pdfbox:app-1.8.10-20150327.210556-4 (in this version
DeviceN is working) and java version 1.8.0_40-ea.
Have a nice day,
Floris

Hi,
I have done a first fix. Wait some time until it will be available at
the bottom of
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/1.8.10-SNAPSHOT/
and tell me if it works, or what "bad things" happen.
Btw I still like to have a workable version of your test code. (I'm
lazy, last time I added all the spaces myself)

I am mistaken. The "g" operator also sets the colorspace to DeviceGray.
From the spec:
G: Set the stroking colour space to DeviceGray (or the DefaultGray
colour space; see 8.6.5.6, "Default Colour Spaces") and set the gray
level to use for stroking operations. gray shall be a number between 0.0
(black) and 1.0 (white).
g: Same as G but used for nonstroking operations

Hmm, you're right there, but the javadoc says that the command is for
DeviceGray.
I looked in the source code, you have to use the command you used for
DeviceN, this one uses the correct command.
/**
* Set the color components of current non stroking colorspace.
*
* @param components The components to set for the current color.
* @throws IOException If there is an error while writing to the
stream.
*/
public void setNonStrokingColor(float[] components) throws IOException
{
for (int i = 0; i < components.length; i++)
{
appendRawCommands(components[i]);
appendRawCommands(SPACE);
}
if (currentNonStrokingColorSpace instanceof PDSeparation ||
currentNonStrokingColorSpace instanceof PDPattern
|| currentNonStrokingColorSpace instanceof PDDeviceN
|| currentNonStrokingColorSpace instanceof PDICCBased)
{
appendRawCommands(SET_NON_STROKING_COLOR_COMPLEX);
}
else
{
appendRawCommands(SET_NON_STROKING_COLOR_SIMPLE);
}
}
I'll think about whether to make a check for the current colorspace in
the other setNonStrokingColor methods if needed.

Re: Separation Space

I tried version pdfbox-app-1.8.10-20150401.225545-14 and the separation
color space is created properly. The color setting operator is wrong
though. I get:
stream
/Cs3 cs
1 g <--------------------- This should be
a 'scn' according to the PDF specifications. g is used with DeviceGray only.
10 10 20 20 re
f
BT
10 10 Td
/DeviceGray cs
/F0 10 Tf
0.5 G
(Hello World!) Tj
ET
endstream
It also seems that in the separation channel 255 bit is mapped to 1
while in the DeviceN case the recipe is specified directly (in the range
of [0,1]): to obtain the above code I used
'contentStream.setNonStrokingColor(255);'. Is this intentional?

I just fixed a second bug, so you'll have to wait again.
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox/1.8.10-SNAPSHOT/
Your version should be one higher than 11.
I was able to create a PDF, it has a black rectangle and "llo" in black.

Re: Separation Space
Posted by Tilman Hausherr <TH...@t-online.de>.
Hi,
There's obviously a bug in the initialization without parameters. The
array should be filled more / or the set method should fill what is
needed. I'll investigate and fix this and come back to you.
Btw, your test code, could you please post it again and so that the
space between "new" and the rest is there? It is missing. Maybe it is a tab?
