"rgb" model fails, color opacity does not work on metapost graphic #542

Closed Cicorione closed 10 months ago

Cicorione commented 10 months ago

Hi @pgundlach

I don't know if this is a regression but rgb model is not working while RGB does; then I am not sure if opacity set on DefineColor is supposed to be read by a Metapost graphic, but it is not.

Not sure if this is useful by any means:

Opacity is not working on other element like frames or circles as well.

Unless I did not understand how opacity works on Publisher... :man_shrugging:

pgundlach commented 10 months ago

There is more than one bug in the implementation. I need to fix them before I can write a solution.

pgundlach commented 10 months ago

I've fixed a few bugs in version 4.15.15; your layout works with that version. (Now available)

Thank you as always for the valuable bug reports!

Cicorione commented 10 months ago

Hi @pgundlach FYI as for this version:

commit 97d8199bd09188c723664c0ce9981756af64aa9d (HEAD -> develop, origin/develop, origin/HEAD)
Author: Patrick Gundlach <gundlach@speedata.de>
Date:   Sun Nov 26 12:59:26 2023 +0100

Version 4.15.15

colors.accent does not apply any color and spcolor("@accent") causes Publisher to stop.

Thanks

I'll fix the other issue.

Cicorione commented 10 months ago

Hi Patric, your layout work here with the symbol @:

 <DefineColor name="@accent" model="spotcolor" colorname="Pantone 116 C" />

Instead in this way:

<DefineColor name="npyellow" model="cmyk" c="0" m="30" y="90" k="0" />

And assign it as attribute from data:

<section secname="HDMI"  accent="npyellow" xmlns:xi="http://www.w3.org/2001/XInclude">

And recall it as variable:

 <SetVariable variable="accent" select="@accent" />

with my graphic (actually your)

<DefineGraphic name="accentroundedcorners"> save corner; corner := 10; filldraw (0, box.height -
            corner ){down} .. {down}(0,corner) .. (corner,0) -- (box.width - corner,0) ..
            {up}(box.width, corner) -- (box.width, box.height - corner) .. {left}(box.width - corner,
            box.height) -- (corner,box.height){left} .. cycle withcolor spcolor("@accent"); </DefineGraphic>

For some reason fails:

I'm afraid I need some sort of value in order to continue,

delete this zero and insert something else;
see Chapter 27 of The METAFONTbook for an example.

pgundlach commented 10 months ago

This works as intended. There is no color @accent.

Next version will allow this:

<Layout xmlns="urn:speedata.de:2009/publisher/en"
  xmlns:sd="urn:speedata:2009/publisher/functions/en">

  <DefineColor name="npyellow" model="cmyk" c="0" m="30" y="90" k="0" />

  <SetVariable variable="accent" select="'npyellow'" type="mp:string" />

  <DefineGraphic name="r"> fill box withcolor spcolor( accent ); </DefineGraphic>

  <Record element="data">
    <PlaceObject>
      <Box height="5" width="1" graphic="r" />
    </PlaceObject>
  </Record>

</Layout>
Cicorione commented 10 months ago

Hi Patrick,

I am not sure I am doing this properly...

sp --version
Version: 4.15.16 (Pro)

However with data this way:

<section secname="Sec01"  accent="'npyellow'" xmlns:xi="http://www.w3.org/2001/XInclude">
[...]
</section>

The color declared at the beginning of the file

<DefineColor name="npyellow" model="RGB" r="255" g="178" b="25" alpha="100"/>

And the metapost graphic that should read the variable value from the data:

<DefineGraphic name="accentroundedcorners"> save corner; corner := 10; filldraw (0, box.height -
        corner ){down} .. {down}(0,corner) .. (corner,0) -- (box.width - corner,0) ..
        {up}(box.width, corner) -- (box.width, box.height - corner) .. {left}(box.width - corner,
        box.height) -- (corner,box.height){left} .. cycle withcolor spcolor( accent );
 </DefineGraphic>

And recalling it with:

<SetVariable variable="accent" select="@accent" type="mp:string" />

Does not compile:

pgundlach commented 10 months ago

Without testing: you should leave out the quotes with 

<section secname="Sec01"  accent="'npyellow'" xmlns:xi="http://www.w3.org/2001/XInclude">

so 

<section secname="Sec01"  accent="npyellow" xmlns:xi="http://www.w3.org/2001/XInclude">

should work.

Hi @pgundlach

I believe something is not quite working well.

A step back before. Since I don't find any method to change dynamically I am trying to use a barba trick

The trick is naming a color like "mycolor" + something; initially I used numbers but:

 Warning: [page 1] The color "test10" has characters in it that confuse
 the metapost interpreter, therefore I have renamed the color
 for metapost to colors.test
Defining color "test10" (152)

Therefore I changed numbers for letters and I made a test to see if the correct string is created:

<Layout xmlns="urn:speedata.de:2009/publisher/en"
    xmlns:sd="urn:speedata:2009/publisher/functions/en">

    <DefineColor name="test" model="RGB" r="0" g="255" b="0" alpha="10" />
    <DefineColor name="testA" model="RGB" r="255" g="178" b="32" alpha="100" />

Unfortunately something is going wrong: opacity.pdf

Color is red when should be green, opacity is not applied. However I moved forward the same with the tests.

However colors and opacity were applied properly, so the barba-trick this time worked... :man_shrugging:

opacity2.pdf

pgundlach commented 10 months ago

The publisher complains because the variable 'special' is only defined for metapost.

Gotcha!

Did you read this? https://github.com/speedata/publisher/issues/542#issuecomment-1842104739

Color came out red instead of green, and opacity wasn't applied at all.

pgundlach commented 10 months ago

Color is red when should be green, opacity is not applied. However I moved forward the same with the tests.

I think it works as intended. You select graphics "r" which uses a fixed color colors.test which has been previously defined with

 <DefineColor name="test10" model="RGB" r="255" g="32" b="32" alpha="10" />

alpha gets ignored in fixed colors (I need to document that). And the color test10 looks red to me.

Cicorione commented 10 months ago

I repeated the test, and perhaps it was another pebcak of mine... 😓
