Set transparent background when background is not constant color in irfanview - colors

I have a photo, and I attempted to set the background to transparent. However, the background is not a constant color, that is, there are slight variations in it. I went through the process of setting the background to transparent, by selecting the transparency color upon saving as a GIF. But as you can guess, only a few pixels in the background were made transparent.
So I do I select a range of pixels for transparency, in irfanview?

Try using the Paint Bucket to fill the area with white. Play with the Tolerance value till it fills the area you want. (Use [Ctrl]Z to undo it till you get it right.) Then set the white area to transparent.

Android Studio automatically adjusted contrast now all of my buttons are light, text color changed to black, how to change it back?
ALL of my buttons were the default blue and they still show up blue in my xml/design window however when I run the app all the buttons are light grey (I think, I'm colorblind, could be teal), my text has turned to black. At one point AS asked me if I wanted to let it adjust the contrast. Now nothing I change seems to change any button color.
Thoughts?

Yellow Text in Solidworks, Can't Change

I'm working on a SolidWorks mechanical drawing generated from a 3-D model I created. I added ordinals to the drawing and text for the sheet title, but all of my text is coming out in yellow:
I've checked that the layer is set to 0, and that the color for layer 0 is set to black. I've also gone through the Options-->System Options-->Colors screen but it did not help me figure out why everything is yellow. It must be a local setting somewhere, because when I try opening the files on another computer it works fine. It's just a pain right now, though, because I need to export to PDF and it shows up as yellow in the PDF instead of black. Is there a setting somewhere that I may have missed?
I would personally go to the settings to determine what type of dimensions SolidWorks assigns the yellow color to.
Tools Options -> Colors -> Color Scheme
By doing that, you will able to figure out what's wrong with the dimension.
Generally speaking, yellow is assigned to dangling dimensions (Dimensions of parts they were modified or deleted).

Custom drawing MT.D borders

I've been playing around with MT.D a bit and love the simplicity of it all.
I have now been working on a completely owner drawn cell using a UIView to do all the drawing and an Element that allows me to use it with MT.D.
Now the only thing I seem to be missing is the ability to control how borders are drawn (or not drawn). If I set the mode to Grouped then I get the indented and rounded borders and Plain I get the simple horizontal border.
But lets say I want to use an image or thicker border for my borders, how do I go about customising this?

How do I change the drawing setting to show the objects filled?

When I create drawing shapes I cant see any color or fill. I know there is a setting that need to be changed so I can see them. Here is a pick of what is happening on my screen:
I draw the shape and all I see is the green outline, any suggestions?
At the bottom of the screen on your timeline there is a green square on your layer, from the looks of it you have click that. This shows layers as outlines.
