Is there a way to transform an image a have on imagekit to black and white via the API?
Something like this https://ik.imagekit.io/demo/tr:oi-logo-white_SJwqB4Nfe.png/medium_cafe_B1iTdD0C.jpg but for black and white.
You can use e-grayscale transformation on your image like this - https://ik.imagekit.io/demo/tr:oi-logo-white_SJwqB4Nfe.png,e-grayscale/medium_cafe_B1iTdD0C.jpg

I have images of human face features like eyes,nose, mouth and i want to re color them in different skin tones. I tried colorBlendMode but that is not giving expected output. So, i wanna know that is there any library or method that can help me to change the color ?
This is how image looks like i want to blend them into single color so that it should look like an actual image
I am working on a simpleITK Image Registration method using Regular gradient descent method. I was interested to know how does the simpleITK able to highlight differences between the Fixed image and Moving images.
For example below is one of the tutorials which shows different coloring with Pink & green colors:
Fixed Image - Red
Moving Image - Green

I want to be able to layer images(PNG) with blank space over other images and have the images underneath still partly visible. right now my Image loading function will prints black space where it should have the background image.
As Noah mentioned, if your PNG images don't have an alpha channel, you can use LÖVE's blend modes.
https://love2d.org/wiki/BlendMode
Try displaying your image with "premultiplied", for instance.
love.graphics.setBlendMode("premultiplied")
love.graphics.draw(myImage)
love.graphics.setBlendMode("alpha")
"alpha" being the default blend mode.
I am trying to build a windows phone live tile. I want some text on the tile that is the accent colour. What this means is that I need to draw some text on the tile that is transparent. I don't seem to be able to write in the transparent colour.
I have a User Control which is 173 by 173 pixels which I save as a png file. I use this png as the image for the live tile. The transparent bits of the image come out in the current accent colour.
Any ideas how to write in the transparent colour in xaml?
This behaviour is to be expected. In your original question you are effectively saying "Write invisible text on top of the image", and that's what you're getting (imagine writing in invisible ink on a photograph). You effectively need to do one of two things.
1) Figure out which pixels are part of the text you're writing, and "remove" them from the image so the background colour shows through, or
2) Write text in the background colour ({StaticResource PhoneAccentBrush})
EDIT
You can probably achieve what you need using an Opacity Mask. Apologies for only providing that as a link as I haven't done this myself.
I would like to make a reflection to an image - like this:
Is that possible in Monotouch?
Thanks!

It is possible, considering that you have full access to CoreGraphics.
There are too many ways of skinning that cat though.
Say you have the top image in "image", I would do something like:
Create a graphics context
Draw the image
Create a bitmap context for the inverted image, with alpha transparency
Render the image invertd
Render a gradient that has been configured to go from 0.5 opaque to 0.2 opaque
Render that on the bottom of the image
Get an image out of the second context
Draw the extracted image into the first context, inverted.
