32 Bit Color at RRD-Graphs

[mojiro]

Since that it is fully supported, why not be implemented to cacti ?

With 2 fast modifications, can be supported... it is tested and it is working nice

MySQL Table
database->table->field->property=value
cactidb->colors->hex->length=8

PHP Code
cactidir/include/config_form.php

original

Code: Select all

/* file: color.php, action: edit */
$fields_color_edit = array(
        "hex" => array(
                "method" => "textbox",
                "friendly_name" => "Hex Value",
                "description" => "The hex value for this color; valid range: 000000-FFFFFF.",
                "value" => "|arg1:hex|",
                "max_length" => "6",
                ),
        "id" => array(
                "method" => "hidden_zero",
                "value" => "|arg1:id|"
                ),
        "save_component_color" => array(
                "method" => "hidden",
                "value" => "1"
                )
        );

What are we talking about here, could it be:

Looks pretty good.

I actually had that coded up for both rrdtool 1.2.x and rrdtool 1.0.x. Of course, this does not work with RRDtool 1.0.x..

where I can find 32 bit color list?

where I can find 32 bit color list?

the difference between 24bit color and 32bit color is the Alpha Channel
also known as Transparency level.

if a 24bit color code looks like #ff0000 (red) then ff = 255, 00 = 0, 00 = 0.
adding two more hex digits at the end of a 24bit color code it is being
converted to 32bit color code, that supports Transparency.

Transparency level, takes values from 00 to ff, where 00 is invisible
and ff is visible.
