I got a "Wrong indexed palette" error when I trying to import a BMP picture. What conditions is needed on a BMP to import on AIS?

I have the same problem.

 

I found some way, but i don't know if could be better.

 

1. Create a New blank picture on AIS

2. Export as BMP picture

3. Use a external editor to load the blank saved picture

4. Save the palette

5. Load your own BMP picture and reduce the colors at 8-bit density

6. Load the saved palette

7. Save the modified BMP

8. Load with AIS the modified BMP

 

But, it could be better to find a good software that allow to use all the palette to get a good conversion.

Allas, congratulations, you are smart guy

 

it's correct way, i use similiar with TIMANTHES v3.0

 

1. Create a New blank picture on AIS

2. Export as BMP picture

3. Use a external editor like TIMANTHES v3.0

4. Load AIS BMP, save palette from BMP (TIMANTHES - Menage color palettes)

5. Load your own BMP picture and select saved AIS palette, TIMANTHES remaping colors

6. Save as GIF (TIMANTHES save BMP as 24bit)

7. Convert GIF to BMP

8. Load with AIS the modified BMP

 

p.s.

TIMANTHES v3.0

You can use Photoshop or GIMP to create your indexed bmp in one step.

Why not use simple effective GrafX2 editor instead of those huge apps? :o

It's freeware, fast, portable (seems to be), works in indexed palette and also use pixel ratio 2x1 (!!!) :)

Interesting, thanks Dracon, I'll take a look at that now, I've not heard of it. You're right that the large apps are a bit ott for 8-bit work really. I tend to use Photoshop primarily for everything because it's fully featured, I know it very well and use it daily in my work. GIMP is a good free alternative too. It has some handy features with regard to working with index palettes.

AIS 1.1.3

 

add import file GIF, PNG (same restriction for palette as BMP)

Great :)

Tebe, is it supposed to be possible to edit the palette in cin mode? or are the 64 colours fixed? As we were discussing on Kaz's page, editing the palette is only corrupting the picture for me.

i editing CIN, CIN palette, saving/loading CIN and all is OK

I'm confused if it is working on your system because I've tried it on several systems here and different os's and I get the same problem. When I edit the cin palette and save the picture, reloading the picture the palette is back to default and the picture is coloured differently than it was saved?

To illustrate the problem, I made some screen grabs to show an example of what is happening..

 

Example 1:

I create a quick test picture in AIS cin mode 64 colours, I draw the first 16 colours in a row.

I save this file in cin format and all is ok. The file loads back with no problem

 

Example 2:

I edit the palette and change 3 colours to grey

 

Example 3:

I save the new test picture in cin mode

 

Example 4:

This is how the new test picture loads after I edited the palette.

The palette is back to default and the picture is incorrect.

you broke AIS :) Tezz

 

p.s.

GRAPHICS 10 it's 9 color (704..712), possible next CIN variation, then 4 colors GRAPHICS 15 mix with 9 colors GRAPHICS 10

Thanks for the explanation of the mode Tebe :) I can see why this happened now.

I will need to prepare my colour mapping in advance with the colours available.

The next CIN variation will be good. I used to use the standard mode 10 a lot. Maybe I can convert some old pictures I did from disk

Hmmm, I am still having problems with the import function of the latest AIS version:

 

1) Created a blank picture with AIS 1.1.3.

2) Exported it as BMP file

3) used XnView to load the BMP file

4) used XnView to save the palette of the BMP file

5)a) instead of BMP I first loaded a GIF-87a picture, so I already had 8bit colours

(no need to reduce colours, at least I think so)

b) just for testing I also loaded a BMP file which had been reduced to 8bit colours

6)a)loaded the AIS palette (64-colour CIN) with XnView => now the former 256-colour GIF looked extremely awful and unrecognizable; b) the same happened to the BMP pict., it looked extremely awful

7) I did not want to save this awful looking pic with XnView, but to show an example here, I did

8 ) errm, I didn`t know if AIS 1.1.3 import GIF into CIN-mode shows something good, I had my doubts... and like I thought, it showed the same awful picture as before and I have no clue how to change that...

 

So at the moment I cannot use the AIS import function to import or convert GIF/BMP/PNG into A8 formats (CIN, etc.) - because after doing so, the pics look extremely awfull... attached you find a picture in GIF-87a format before (256-colours) and after the conversion with AIS (64-colours CIN palette).

 

Any ideas what I did wrong or hints what I can do to get better results ?!? -Andreas Koch
