runcommand launching images for ANY theme

meleu

Hello friends.

I'm very very busy currently but have found some time to work on this code.

I made available many options from the command line, no need to edit the script anymore (oh, and speaking about the code, it is much more clear and organized now. Hey bash hackers, feel free to edit and improve the script).

There is space to new features (such as a semi-transparent belt behind the logo), but I don't have time to look at it currently.

Have a look at the help message to have an idea of the features:

USAGE: generate-launching-images.sh -t theme-name [options]

Use '--help' to see all the options

-h, --help                   Print the help message and exit.
-t, --theme THEME            Create launching images based on THEME. This is
                             the only mandatory option in order to generate
                             the images (see --list-themes).
--list-themes                List the available themes and exit.
--extension EXT              Set the extension of the created image file
                             (valid options: png|jpg).
--no-ask                     Do not show the created images and ask for
                             confirmation (blindly accept the created images).
--loading-text "TEXT"        Set the "LOADING" text (default: "NOW LOADING").
--press-button-text "TEXT"   Set the "PRESS A BUTTON" text (default:
                             "PRESS A BUTTON TO CONFIGURE LAUNCH OPTIONS").
--loading-text-color COLOR   Set the color for the "LOADING" text
                             (default: white).
--press-button-text-color COLOR  Set the color for the "PRESS A BUTTON" text.
                                 (default: gray50).
--no-logo                    Do not put the system logo on the created image.
--destination-dir DIR        Put the created images in DIR directory tree
                             (default: /opt/retropie/configs/).
--system SYSTEM              Create image only for SYSTEM (the default is
                             create for all systems found in es_systems.cfg).
--show-timeout TIME          Show the created image for TIME seconds before
                             ask if the user accept it (see --no-ask).
--solid-bg-color [COLOR]     Use a solid color as background. If COLOR is
                             omitted, use the color specified by the theme.

Some tips about specific themes:

material

Use --solid-bg-color and omit the COLOR.
Use --press-button-text white.

tronkyfran

Use --extension jpg (smaller file size but the image is still beautiful).
Use --no-logo (most of the background images already have the system logo somewhere in the picture).

io

Currently the script is unable to create launching images for the io theme (due to xml peculiarities), but if you run the script with the material theme and --solid-bg-color black option, it'll generate some neat images that match fine with the io theme! ;-)

luminous

Use --loading-text-color black.

general tips

If you don't like the generated image for a specific system, you can run the script experimenting other options and using the --system SYSTEM option. It creates an image only for the system specified.

If don't want "LOADING" or "PRESS A BUTTON" text, use the options omitting the text. Like this:

./generate-launching-images.sh -t tronkyfran --no-logo --loading-text --press-button-text

As a limitation, the "LOADING" and "PRESS A BUTTON" text can't start with -.

That's it. I hope you enjoy. Let me know if you find some problem.

Cheers!

@daeks Would you know how to put a semi-transparent belt behind the logo?

Look at this image and you'll see how a semi-transparent white belt behind the logo can be useful.

tg16

I know the Image Magick docs are very rich, but if you already know the trick it would be greatly appreciated. :-)

BTW, I think it's something with the -draw 'rectangle ...' option.

meleu

F#CK YEAH! I've implemented the "semi-transparent white belt behind the logo" option!

--logo-belt                  Put a semi-transparent white belt behind the logo.

Example:
Command:

./generate-launching-images.sh -t clean-look --extension jpg --logo-belt --system pcengine

Generated image:

Update your script:

wget https://raw.githubusercontent.com/meleu/share/master/generate-launching-images.sh

@meleu
Awesome! Works great but I should note something...

./generate-launching-images.sh -t clean-look --extension jpg --logo-belt --system pcengine

The "clean-look" doesn't have art for "pcengine" so if you type the above in exactly, you get an error.

meleu

@backstander said in runcommand launching images for ANY theme:

The "clean-look" doesn't have art for "pcengine"

It's not true on my RetroPie:

prompt$ ls -l /etc/emulationstation/themes/clean-look/pcengine/
total 8
drwxr-xr-x 2 root root 4096 Jan 10 14:54 art/
-rw-r--r-- 1 root root 3300 Jan 10 14:54 theme.xml

Maybe there's something with you customized ~/.emulationstation/es_systems.cfg file...

EDIT: I think I need to improve the errors feedback to the user...

meleu

@backstander could you run it again redirecting the stderr to a file and then post the content of the file here?

Step 1
Run the following command:

./generate-launching-images.sh -t clean-look --extension jpg --logo-belt --system pcengine 2> error_msgs.txt

Step 2
Paste here the content of error_msgs.txt file.

backstander

@meleu
error_msgs.txt

WARNING: failed to prepare the background image for "pcengine" system!
WARNING: The launching image for "pcengine" was NOT created.

It does have art but on ES, I get the white screen for "pcengine"...oh wait! I'm asking it for the "tg16" art!

ls -l /etc/emulationstation/themes/clean-look/tg16
ls: cannot access /etc/emulationstation/themes/clean-look/tg16: No such file or directory

Sorry, forgot that detail ;-)

meleu

@backstander the tg16 logo seems to be the default on clean-look (rather than pcengine).

Could you please execute this:

bash -x ./generate-launching-images.sh -t clean-look --extension jpg --logo-belt --system pcengine 2> error_msgs.txt

And then paste the error_msgs.txt in ghostbin.com? (it'll be a big file this time)

meleu

@backstander Oh! Now I've got what's the problem in your system. Your es_systems.cfg has this config:

    <platform>pcengine</platform>
    <theme>tg16</theme>

And the clean-look has no tg16/theme.xml.

Here is the workaround for it:

cd /etc/emulationstation/themes/clean-look/
sudo ln -s pcengine tg16

In other words, create a symbolic link to pcengine theme directory named tg16. It worked fine here. ;-)

backstander

Thanks @meleu
I just tested this with the link and it works great!

meleu

Update:

added --list-systems option to List the installed systems on your RetroPie (get this info from es_systems.cfg).
added more info about the errors found while trying to create the images. Example:

Any feedback is welcome. :-)

meleu

UPDATE
Added the --all-systems option to Create image for all systems of the chosen theme. I think it can be useful for theme makers who want to release a launching images pack for his/her theme.

@meleu

How do you install scripts?

backstander

@FlyingTomahawk
It's on the first post

wget https://raw.githubusercontent.com/meleu/share/master/generate-launching-images.sh
chmod +x generate-launching-images.sh

meleu

There's a hope to see it as a part of RetroPie-Setup: https://github.com/RetroPie/RetroPie-Setup/pull/1881

:-)

@backstander

Are you following me? Hehehe...
It's the second time that you helped me out.
Thanks! ;)

@meleu
That would be really awesome. It's a very nice feature and looks waaaaaaay better than that ugly interface.

backstander

@FlyingTomahawk

Are you following me? Hehehe...

Haha, I just happened to be "Watching" a couple of the same threads that you've been posting on and I just happened to be on when you posted that ;-)

@meleu

Finally I got it working. Had a bit trouble with all those commands. Linux is very new to me.
I had trouble to use this with my Futura theme but that is my fault. I had a space in the theme name Futura 10px that is not good, something that I have to change in the next update.
It should say futura-10px then I can run the linux command to create the images.
It worked great even with my custom systems like CPS or Psikyo.

Thanks again for all the work. Now I just wished the roms would take longer to load. Haha... before I was always happy if they loaded fast so that I don't have to see that ugly grey box.

@FlyingTomahawk Is your theme available somewhere?
