OK... let me see...

I've downloaded GIMP 2.8
Installed the full installation
Dragged the image to the program
Clicked on File > Export As
...

Here there is no advanced tab or anything like that. If I click Export, then there is an Advanced Options tab to click on, but it is greyed out as if not available...

Any ideas?

Here's a screenshot of the issue... this is with BMP chosen in the export option, and you only see the Advanced Options in the popup once you click on export, but as you can see, it's greyed out so you can't choose anything, and I've tried activating the other options to get that to open.

ahh, quick question also... I read someone mention the images had to be 96x96, but this was for the 6S... is it the same for the 7E?

Just to let anyone else know in case they encounter this issue, after a lot of looking around, I found that I needed to also download a script and a palette package, then after go to IMAGE->MODE->DITHER RGB565. Then use the export option on the newly opened image, now allowing to make advanced adjustments, saving in RGB565, and it worked.

It's important to note that there are two different kinds of icons used on these Devos, as the two branches under the "Model Icons" branch shows:
  • Color icons for DEVO 6, 8, 12
  • BW icons for DEVO 7E, 10
...and the requirements for each type are different. This thread so far seems to discuss almost exclusively the color icons. The BW icons for DEVO 7E, 10 need to be smaller and use only two "colors," black and white. Here's what the Devo 7E/10 manual says on the subject:

All available model icons (must be 52x36 pixels). Model icons must be saved as 16-bit BMP files in either RGB565 (non-transparent) or ARGB1555 (transparent) format.


The 52w x 36h size is different/smaller than mentioned most times in this thread, i.e. it is NOT 96x96. And while these images must also be 16-bit BMP files in one of the above mentioned formats, only two of the available ~67,000 colors get used. Every pixel is either white or black (I think the white ones could also be set as transparent). So you need to use a few image editing features (you figure out which, depending on which software you use, e.g. PhotoShop, GIMP, etc.) to help you get the image:

  1. sized to dimensions with a 13:9 (52:36) aspect ratio (makes scaling easier in later steps)
  2. in grayscale ('desaturate' is your friend ;-) )
  3. scaled down to 52x36
  4. all the grey pixels changed to either white or black

It helps to tweak that final image a bit since it's so small and blocky, and the conversion to B&W may be less than ideal. That is, you may manually change some dots from one "color" to the other. It's hard to simulate any detail as this low resolution.
I wanted to see something here about the unique requirements for the small B&W icons.

P.S. I suggest you Google for tips on how to use your particular image editor to do the things mentioned above. It would be a lot to try to describe here. Plus it would repeat what others have described better on web sites devoted the subject. And I don't want to assume you use one program or another. I use GIMP, but PhotoShop is great to. In theory, these icons could be drawn in a vector program like InkScape, then exported as a BMP file. That again is beyond the scope of this post.

Ok guys I've downloaded the GIMP app and got in installed (not easy for someone like me who refuses to use torrents).

The issue is now that I dont understand how to draw an image from scratch. I setup my image at 52x36, grayscale and set transparency then I select the line tool and try to draw a line but just a single dot takes up 2/3 of the canvas. I looked around and found where I could change the type of line its drawing and I can get it to make a pre-drawn straight line that's skinny enough to work but then I cant change it's length and it can only be exactly horizontal or exactly vertical.

Do I have to start with a different image from something else (say MS Paint) or can I somehow draw the image from a blank canvas? Note other than playing around with Paint this is literally the first simple 2D drawing program I've ever had a need to try and use so at this I'm a total noob,

I use MS Paint to get the size and icon down to the 52x36, but leave it as color. I then use GIMP to change the colored pixels black (with the Colors->Threshold function) and then export the icon to bmp with the correct export settings. I can't figure out how to size stuff in GIMP... so I just do it how I know. :blush:
