loading BMP in Micro-8

Here is a routine to read a BMP image directly on the Micro-8. Make sure the BMP file is max 16 colors, max 400x240 resolution.

Here is how to convert the image in the correct BMP format using GIMP.

• Open the image in GIMP.
• Go to Image → Mode → Indexed...
  • Set Maximum number of colors to 16.
  • (Optional) Enable Color dithering for smoother gradients.
• Adjust the image size if needed:
  • The Micro-8 loading routine supports images up to 400×240 pixels.
  • If your image is larger than this, use Image → Scale Image... to reduce it to 400×240 or smaller before exporting.
• Go to File → Export As..., and choose a filename ending with .BMP
  • When exporting, check “Ignore alpha channel”.
  • Make sure RLE compression is unchecked.
  • Then click Export.

 


 

Awesome, thanks @David.
Just to clarify, this routine will load the PC Image format known as BMP into the bitmap memory. Not to be mistaken with Micro-8's native BMP (bitmap) files produced by the Image Editor.

Update 0.9 :

- fix in loading picture 
- better palette conversion
 

Here is a modified version that prompts the user for the name of the BMP file to convert (Windows BMP, 16 colors, 400×240), and then converts it to the Micro-8 format, generating CONVERT.BMP and CONVERT.PAL.Tip: To convert an image to a 16-color BMP file, you can use the online converter available here: online-converting.com/image/convert2bmp/
