LucidSurf Posted October 29, 2018 Posted October 29, 2018 Hello, I'm sure it is out there in this forum but spent 10 min searching with no results. I have a photo of a face that I would like to get laser engraved. How to you take this photo and turn it into a "bitmap" image as I am reading to do? Or at least turn a photo to a true B&W photo with dots? Thank you
Dan C Posted October 30, 2018 Posted October 30, 2018 Hi LucidSurf Affinity Photo can't currently export to the .bmp (bitmap) format, however the phrase 'bitmap' is occasionally used to describe a raster image of a different format, such as .JPEG. What specific file type does the laser engraver require? In terms of a B&W photo 'with dots' you can use the halftone effect under Filters>Colours>Halftone. I hope this helps!
Fixx Posted October 30, 2018 Posted October 30, 2018 Affinity Photo does not really handle 1-bit bitmap format. It is possible to simulate 1-bit appearance in RGB and it is possible to export 1-bit GIF or PNG, but results are always dithered and can be unpredictable.

How do I do that then? I scan a lot of black-and-white images. VueScan scans them as a B/W tiff but they load into Affinity as 8-bit RGB. I convert them to greyscale and apply a severe S-curve (essentially a single step) and have to save as png-8. John Windows 11, Affinity Photo 2.4.2 Designer 2.4.2 and Publisher 2.4.2 (mainly Photo).

mrv Posted January 18, 2019 Posted January 18, 2019 I have been using affinity photo to do this. I'm not that great with the program. only about a week. i have taken the pic to black & white then resided it export out as a jpeg then input it into the laser printer software. works good so far. still needs so work but i think its on the laser printers side.
