BMP is not shown on export options


Recommended Posts

Hi all.

On Windows and Photo 2.

I have a 4bit bmp image, indexed as shown in Photoshop, which I want to do a small amend and then save it as it is.

Specifically, I want to move the text on the top and save.

Don't want to change anything in it's properties.

When I go to the export option, the BMP is missing from the format list.

Any idea what I can do? Example attached.

In Photoshop for example, I just move the text and hit save and it's done.

Thank you.

If you have imagemagick available you can open the file in Photo
make the edit
copy to clipboard
in a cmd or Ps window do
magick clipboard: -colors 4 bmp3:test2.bmp

A bit oddly "Save" command is left non-grayed for opened files which is very misleading since for certain formats saving vs. exporting is actually available and the command should clearly indicate ability or inability to save to the opened native format by using enabled / grayed out menu command, instead of just automatically showing the Save As .aphoto dialog box when saving back cannot be done (the price is that if "Save As" fallback is always assumed, then the user might actually save back and inadvertently overwrite the original file in cases where saving back is actually supported). But Affinity apps do this for other file formats, too, e.g. SVG, so I guess this is "by design".

Save is enabled for raster formats that you've Opened, and for PSD if you've Opened one and you have the "Save over PSD" option enabled in Settings. And for the Affinity file types, of course.

why force colors to four instead of allowing the maximum of 16 (in a 4-bit image)?

magick identify -verbose test.bmp
reports 3 colors so I used 4 but yeah 16 won't do any harm

it also shows uncompressed so I left that alone. If you add say
-compress RLE
then the file size reduces dramatically but maybe the OP's program won't handle it, Photo can't although Photoshop, Photos, Irfanview and Chrome can

BMP isn't in the list of supported formats that can be opened although it does work.

wow, thank you all for your help with this!

It's a pitty Photo cannot open such a simple format that has been around since day 0!

I have the alternative of creating tiff's instead so I think I will go that way.

Thank you all!
