shen Posted December 16, 2019 Posted December 16, 2019 Hi Does anybody know how to change the black scanned text into another colour ? file included as uploaded image Is this possible in photo or publisher ? Quote
GarryP Posted December 17, 2019 Posted December 17, 2019 Welcome to the forums. A simple Recolour Adjustment could be what you want and that function is available in all Affinity apps. Quote
v_kyr Posted December 17, 2019 Posted December 17, 2019 Even easier to use and much more versatile, if you vectorize the bitmap text and use that then instead afterwards. vanhetalledaagse.afphoto screencast.mp4 Quote ☛ Affinity Designer 1.10.8 ◆ Affinity Photo 1.10.8 ◆ Affinity Publisher 1.10.8 ◆ OSX El Capitan ☛ Affinity V2.3 apps ◆ MacOS Sonoma 14.2 ◆ iPad OS 17.2
GarryP Posted December 17, 2019 Posted December 17, 2019 One issue with vectorising is that you might lose some detail. For example, the last “s” on the right has some artefacts on it – top-left – which could be of importance but may be lost during vectorisation. These artefacts could be on the original or they may have come from the digitisation process. If they are on the original they may be a result of using a particular combination of pen+ink+paper where the ink hasn’t affected the paper in quite the same way as in other areas, especially on older documents using rough paper written on with quill using certain kinds of ink. This may, or may not, be important – it depends on what you want. Vectorising is probably the best way to go in this instance – it looks much smoother than the raster version – but it’s worth checking the detail and making a decision. Quote

The whole is smoothed for edges during my vectorization, one can customize the degree of smoothness and rounding etc. for vectorization since the shown bitmap original was extremely pixelized (stair steps) for the scanned letters. Further one can adjust the nodes for that if wanted/needed, I didn't since its a quick turn and not my own personal work here.

GarryP Posted December 17, 2019 Posted December 17, 2019 If you supply a link to the vectoriser you used then shen can give it a try and see what they prefer. Quote
v_kyr Posted December 17, 2019 Posted December 17, 2019 I doubt that, since I used my own custom one for that which is not public available ... Further I don't know which OS the OP uses. - However the OP can try out one of the common commercial, freeware, or online tools instead ...

walt.farrell Posted December 17, 2019 Posted December 17, 2019 In Photo you could nest a Fill layer into that pixel layer: (This probably also works in the Photo Persona of Publisher, but additional steps may be needed, such as rasterizing the layer.)

GarryP Posted December 17, 2019 Posted December 17, 2019 Also, in any of the applications, you can add a Colour Overlay Effect. walt.farrell 1 Quote
v_kyr Posted December 17, 2019 Posted December 17, 2019 Well even if in this specific case many roads lead to Rome here, maybe we should also note, that a color fill clipping/color overlay etc. will only work for separate bitmap objects with a transparent bitmap image background here. For non transparent rect bitmap text (on white or whatever) those things won't work at all.

Even if I make the background white (create white fill layer below the text layer, merge down) the recolor adjustment approach still works: Quote -- Walt Designer, Photo, and Publisher V1 and V2 at latest retail and beta releases PC: Desktop: Windows 11 Pro 23H2, 64GB memory, AMD Ryzen 9 5900 12-Core @ 3.00 GHz, NVIDIA GeForce RTX 3090 Laptop: Windows 11 Pro 23H2, 32GB memory, Intel Core i7-10750H @ 2.60GHz, Intel UHD Graphics Comet Lake GT2 and NVIDIA GeForce RTX 3070 Laptop GPU.

Probably. - I meant the general behavior of raster graphics vs vector graphics here. For raster/bitmap graphics recoloring works, if (-like in this case-) scanned text is on a transparent or even colored rectangular area without any other pixels having the same color as the text then has. - But as far as there are maybe other pixels of the same as the text color inside the bitmap area those are always too affected then by recoloring (suppose text on a pattern rect or the like), as far as these are not masked out accordingly. For the OP's sample what I meant in general is visable here, see the other leftover raster scan pixels ...
