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 12426 Jul 23 10:22 Bobomb.bmp -rw-r--r-- 1 westlund2 45916 27786 Jul 23 10:22 Boo.bmp -rw-r--r-- 1 westlund2 45916 25482 Jul 23 10:22 BulletBill.bmp -rw-r--r-- 1 westlund2 45916 10890 Jul 23 10:22 DoomMarineFace.bmp -rw-r--r-- 1 westlund2 45916 4746 Jul 23 10:22 Doomhelm.bmp -rw-r--r-- 1 westlund2 45916 22410 Jul 23 10:22 Exploder.bmp -rw-r--r-- 1 westlund2 45916 4746 Jul 23 10:22 Floater.bmp -rw-r--r-- 1 westlund2 45916 10122 Jul 23 10:22 Goomba.bmp -rw-r--r-- 1 westlund2 45916 3210 Jul 23 10:22 LinkCactus.bmp -rw-r--r-- 1 westlund2 45916 4746 Jul 23 10:22 LinkSkullBouncer.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.bmpAll 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?
I think the issue might be the filename I’m using for the strip — is it just a single file named 0.bmp?
