MxHeppas New Gradientmap "tool" (does something what Native one does not) for Affinity Photo

[MxHeppa]

this is procedural texture preset. and what this does differently to included gradientmap:
you can do gradient map beetween two colours what have both own alpha value. this allow "remap" image for example beetween red and transparent what is impossible factory included Gradientmap. but limits you can use only two colours (what i you can select) and no swatches and you dont have blend modes with original image. and gradient position is average of original pixel RGB values. i try develop other useful ones allready have one idea another idea if develop many put them own thread. i soon when i have time upgrade variable names to better in this. to easier understand how this works even idea is very simple.

Could there something  be missing in you post (the preset file)?

besides the textual description, some screenshot how it works and an example document would help to understand.

[MxHeppa]

yes i can do. screenshot. and try i tell more there is eight sliders what define colours what used for gradient values are first colour red,green,blue,alpha

and second colour red,green,blue,alpha.
uinlike "factory" gradientmap there is also alpha values used colours. then you can do for example image beetween black and half drapsparent yellow fpr example.
ps. i develop soon example images.
there is three iamges one what shows gui. and one show orignal image and one show one gradientmap applied.

here i put this modified image top of project where i have simply word UNICORN. becouse image is partly transparent end looks this. normal gradientmap modified images are fully opaque. is both ends own alpha value. i hope these images help understand its idea.

[MxHeppa]

you can download this modified image and put top of any your document see what i mean. or of course i can do example document even. examples are ugly becouse i done them quickly.

there is example project in affinity photo. photo is processed using this procedural texture after this is putted this example and its partly transparent as you see. i used font Arial font for text becouse i understand is available at least pc/mac side i dont know ipad.
