I want to use a background image for a kivy button. I have used the following builder string:
<MenuScreen>:
BoxLayout:
Button:
background_normal: './Pictures/my_background.png'
The image is displayed, however, it is much darker than expected and partially inverted. What do I have to do in order to display my original image without changes?
The resulting button

I think your problem is that the two colors in your image are grey and transparent (the white appearing areas are actually transparent in your image). In a Button, the background_normal image is multiplied by the background_color which is also a shade of grey by default. So what you end up with is the background grey showing through your transparent areas (white areas above) and your grey appearing everywhere else. So there is not much contrast. See the Button Docs for more information.
You can modify your image (using something like Gimp) to replace the transparent areas with a white color, and perhaps change the grey colors in your image with black. The distortion of the image is due to Kivy fitting your image to the button size.
Here is your image edited as I described. You should be able to click on it and download it.
My requirement is to fill specific color on specific area of an image. But the image should be an image taken from iphone camera or photo gallery. For example, I could take a picture of me with a blue shirt, the app should allow me to change the color of the shirt to red.
Exactly the functionality of "Paint bucket" tool of the photoshop.
I found couple of approaches
1) Using MASKS with prepared images
color selected part of image on touch
Fill color on specific portion of image?
Scanline Flood Fill Algorithm

2) Using GLPaint (Actually this is NOT the solution I am running after)
My question is,
Is it possible to color specific area of a image WITH OUT having MASKS or with generating masks for the image on run time?
Scanline Flood Fill Algorithm does that in to a certain level. But when it comes to real time images(like selfie images) it wont work correctly?
I am developing a book app. Book pages are images. At a time one image is shown on iphone screen. Image contains lines(Paragraphs). I want to highlight the whole paragraph on touch on that. Is it possible to highlight the paragraph or make overlay on the whole paragraph or change the color of that paragraph. Any Help please?
As your book page is an image, the only way you can do it is to either change the image or add a view on top with a color and an alpha value. With the latter you also overlay the letters of course, so the effect will kind of blurry your text.
Next to that, recognising the paragraph won't be trivial, depending on your image quality. The same counts for changing the image - if your background is not a clean color you have to introduce some threshold for which color is the background color and should be changed to the highlight color.
For how to change the color of specific pixels in an UIImage see here:

How can we change the Hue and Saturation of an Image inside a PictureBox?
Below is a screenshot of an app I wrote for Windows Phone. The first image shows a blue note icon, the second, shows an orange-red note icon.
Basically what I am trying to accomplish is change the hue/saturation of certain UI elements (toolbar icons (with images)) when hovered-over. Instead of loading all these images and having 2-3 different color variations for each image. I would prefer to just have 1 image and just programmatically change the hue and saturation accordingly when the image is hovered over:
Original image:
Altered image (desired effect when changing hue/saturnation programmatically):
My base image is a complex shape with multiple colors and an alpha background.
My shimmer effect is a white slanted gradient with an alpha background.
My goal is to animate the shimmer image over top of the base image, but make the alpha values of of the shimmer match those of the base image.
I've only used layer masks to hide areas based on the color, not to both show AND hide parts of an image. Will I need to create multiple masks to achieve this? A white version of my base image that will show through the masked shimmer image, all on top of my colored base image?
Since your shimmer effect is created by moving a single image/layer over a base image, you only need one mask in the shape of the non-alpha values in your base image. You will likely need to use a container view for your shimmer image view/layer that you overlay onto of the base image, then set the image mask on the container.
