Description sergey_feo 2005-02-16 18:05:06 UTC
Sorry for my bad english :-)

IMHO this feature may be usefull: printing of presentations in inverse colors.
The reason is: ~ 30 % of presentations what I seen was on dark background. And 
peoples printed such presentations "as is"; results was not very good: great 
toner/inc requerements and great presentation of all printer defects :)

Of course, many printers have option "inverse colors", but not all. Especially 
network printers...

OK, I provide feedback on this automatic request now :-)
I will attach an example presentation slide. How should it printed from
OpenOffice without this feature?
Yes, other way is exists: it is the option for disable background pictures as in
MS Office. I think this option mean also auto-changing all font colors to
appropriate values.
I can't find such option in OpenOffice 3.0 beta.

P.S. Negatives may be different. We may do "classic" inversion. And Sun n
attached slide will be blue. Or we may do brightness inversion. Sun will be
yellow, only shadows will be strange. I will attach example screenshot of
brightness inversion. It can be important if we use colour printer. By the way:
standart "brightness inversion" command in the GIMP works bad for example
picture. I use the next method: break picture to 3 layers with YCbCrITU 709, 
model, inverse "luma-y 709" layer, make some correction by brightness curve and
finally put this 3 layers back in one by YCbCrITU 709 model.

Nicolas Garcia – 6/5/2010
I check this feature in a laptop with the following characteristics:
Soy Vaio VGN- CS320J
Widows Vista 64 bits
Ooo version: OOo-dev 3.3.0 DEV300m77 (Build:9496)

This report is divided in the following sections:
A) Why black backgrounds are important and widely used in presentations.
B) Why customers need paper copies of their presentations
C) What are the problem when printing black background presentations
D) What are the current solutions for customers.


I think that this feature would be important because many people prefer to use 
black background on their presentations for the following reasons:

1)Black background in business presentation has an important roll. Black is 
knowing by its characteristics as a color that transmit security, formality, 
trust, and it's also used for describe high technical issues. All these black 
color emotional characteristics lead to this color to become very important and 
widely used in business presentations. In addition, dark gray  is commonly used 
as well. 

2)It also preferred by people who use projectors in their presentations. People 
mention that using a black background removes the frame, and a image can be made 
larger and thus more visible. This is important specially if the image doesn't 
have the same proportion as standards slides. I.e., 2:3 for film slides; 3:4 for 
computer screens.

3) Black background is also recommended when presenting on places with low 
light. The reason of this is because several researches affirm that the stress 
on the eyes of the audience is much less when using dark background on low 
illuminated places. 
Additional Comment: Youtube add a function on its webpage called “turn off the 
lights” which  basically makes the background dark when watching a video, 
removing the bright white and giving less strees to the eye of the viewer.

5)Black background (or black big images) are tend to use in presentations of 
many topics/areas like: aerospace, meteorology, medical researches (x rays, 
ecography, MRI), high tech companies (black is also synonym of innovation and 

For all these reasons black background are  widely used in presentations.


Reasons of why people want to make paper copies of a presentation: 

1- Paper copies are commonly distributed among audience before, during or after 
the presentations to remember highlights issues of the speak.

2- Many companies/presenter distribute paper copies to people who could not 
attend to the presentation.

3- Students tend to print presentations before class to take notes during 

4- Many organizations, like educational or research institutes, tend to publish 
paper copies of interesting presentations on hallway whiteboards, where people 
have easy access to them.


Main Problem when printing presentations:

1- Much ink required to print paper copies.

2- Quality of the copies. 
White on black background is not very legible for the human eye when reading on 
paper, unless using a good printer with high resolution (which means a lot of 
ink wasted). Besides, when trying to photocopy the original handout (to cut 
costs) the quality of the outcome is affected considerably, resulting in 
unreadable material.

Current Solution:
Manually change the background and the text color of each slide. This is a 
tedious process which waste a lot of time and patient for the customer. If 
presentation uses dark pictures, customer would have to use an additional 
software to inverse the colors of each of the images. Then, when saving the 
file, customer has to decide either loose the original digital copy of the 
presentation or keep two copies of the same file (one with colors inverted). All 
these process would be very unpractical and uncomfortable specially for people 
who does many presentations like teachers or public speakers.  

General Comments:
Microsoft Power Point doesn't include this feature on the software so it would 
be a good opportunity to offer something extra above the competition. 

Adding a negative color feature will save time, effort, and money (saving ink) 
to the customer.
