Converting GIFs to Game Frame BMPs

[john]

I threw together a quick shell script to convert people’s GIFs to Game Frame BMPs:

#!/bin/bash

GIF="$1"

TMPDIR=$(mktemp -d 2>/dev/null || mktemp -d -t 'gifconvert')

# Get frame count for gif - last frame is n-1
#FRAMES=$(identify -format %n "$GIF")

# Pull full frames from gif
convert "$GIF" -coalesce $TMPDIR/%d-"$GIF"

montage $TMPDIR/*.gif -mode concatenate -type truecolor -tile 1x "$(echo "$GIF" | sed 's/\.[gG][iI][fF]$/\.bmp/')"

ls -l "$(echo $GIF | sed 's/\.[gG][iI][fF]$/\.bmp/')"

Depends on ImageMagick. I’m at work so I haven’t had a chance to test the results out on my frame yet. Still a lot of polish that should go into it. For example it assumes all frames have the same delay. Will add some logic to try and account for that.

Here’s what I converted so far:

-rw-r--r--  1 westlund2  45916   1674 Jul 23 10:22 BlueKeyCard.bmp

-rw-r--r--  1 westlund2  45916   3210 Jul 23 10:22 MarioBlock.bmp
-rw-r--r--  1 westlund2  45916  30858 Jul 23 10:22 MarioCapeGuy.bmp
-rw-r--r--  1 westlund2  45916   6282 Jul 23 10:22 MarioCoin.bmp
-rw-r--r--  1 westlund2  45916   6282 Jul 23 10:22 MarioCoin2.bmp
-rw-r--r--  1 westlund2  45916   3210 Jul 23 10:22 MarioShell.bmp
-rw-r--r--  1 westlund2  45916   7818 Jul 23 10:25 Space-Invader.bmp
-rw-r--r--  1 westlund2  45916   6282 Jul 23 10:22 Walker.bmp

All appear to be under the max resolution – with MarioCapeGuy.bmp coming the closest.

I’ve attached a couple of my first passes. I’ll report back on their functionality when I get home.

I couldn’t get the filmstrips working so I switched to the format that all the animations on the micro SD currently have. Updated script:

#!/bin/bash

GIF="$1"

TMPDIR=$(mktemp -d 2>/dev/null || mktemp -d -t 'gifconvert')

# Get frame count for gif - last frame is n-1
#FRAMES=$(identify -format %n "$GIF")

# Pull full frames from gif
#convert "$GIF" -resize 16x16\! -coalesce -type truecolor $TMPDIR/%d.bmp
convert "$GIF" -coalesce -type truecolor $TMPDIR/%d.bmp

#montage $TMPDIR/*.gif -mode concatenate -type truecolor -tile 1x "$(echo "$GIF" | sed 's/\.[gG][iI][fF]$/\.bmp/')"

mkdir "$(echo "$GIF" | sed 's/\.[gG][iI][fF]$//')"

cp $TMPDIR/*bmp "$(echo "$GIF" | sed 's/\.[gG][iI][fF]$//')"
ls -l "$(echo $GIF | sed 's/\.[gG][iI][fF]$//')"

I’ve attached a few sets up bmp files I’ve put together so far.

Nice work, John! What was the problem with the filmstrip versions? Was there an issue reading the files, or writing the correct CONFIG.INI file?

[john]

I think the issue might be the filename I’m using for the strip — is it just a single file named 0.bmp?

[Jeremy Williams]

Yes, for a filmstrip it’s just be a single 0.bmp (maximum x/y resolution of 32,000). If you want to attach the file you made here, I can take a look.
