LucidSurf Posted October 29, 2018 Share 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 Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted October 30, 2018 Staff Share 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!

Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible. Many thanks!

Fixx Posted October 30, 2018 Share 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.

mrv Posted January 18, 2019 Share 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.
