Add Clipping Mask on Pen Stroke Path

I have a text object with a white pen stroke running through it. I want to make that path a clipping mask, so that it would be a transparency instead of a white line, so that I can put it on any background.
When I do a Clipping Mask however, this is what I get:
My pen stroke is the top-most layer as well.
Assistance plz.
First you need to expand the stroke so it is a closed path: Object>expand
Next fill the new shape black place it where you want it. Copy it and delete it.
Now select the text object and create a new opacity mask. Paste your clipping shape in the opacity mask. uncheck clip.

Remove selected color from image (grayscale graphic)

Hi guys! I have the following task: I must paint the black and white house, leaning to a result as the colored one.
I figured out, there must be a way to somehow "remove" the white color, so there is only the black outlines left. From there I will make an underlayer and will insert color/materials etc.
The hard part and the essential in my question is: The black outlines are ranging from true black to very light grey. Is there a way I can somehow delete all white (0,0,0) pixels and for the others: the more "black" they have, the more opacity they get. So a grey pixel with a value around (126,126,126) will be left, but with a 50% opacity.
have you tried, copying the same image on top of the original image, change the copied image blending mode to overlay, use the select tool on the white area, and then click the select tab on top menu, from that tab click select similar,so you have all the white area selected, then select the original layer, and then erase, you can also erase delete the copied image. Good Luck!
Yes you can,
Open "Select" menu and choose "Color Range", it will open a dialog box, inside that box you can choose from the drop down at the top if you want to select Reds, Yellows, Greens, etc. or you can select Sampled Colors with the eyedropper tool, so you can select the white color from anywhere at the image then you can handle the color range sensitivity from the slide bar called Fuzziness, the lower number is the lower range of white color and vise versa :)
As Ahmed Alaa said, use the "Color Range" tool, but for coloring in black and white images, see if my Youtube tutorial can help.

labeling and saving transparent layer in photoshop

I am a newbie to photoshop. I have some images that I need to label by hand to feed to a machine learning algorithm for classification.
The labeling accepted by the code bundle I will be running on is supposed to depict the features I am interested in, and the other unlabeled pixels are to be black.
For instance, I have a picture of land, and I will have to paint on it with red to mark the rocks, and blue to mark the soil. The other regions in the picture will be black. SO my labeling image should have red (rock) and blue (soil) and black (unclassified).
I am told I need to do this with transparent layer on top of my actual picture, and I can paint on the transparent layer as I want, and save that transparent layer as my label image.
My questions are:
How do I draw on the transparent layer (I am reducing the opacity to
0 because I want a transparent layer, right?)
How do I paint the unlabeled pixels black? (because that is what the program recognizes
as unclassified)
How do I save the transparent layer as a 8-bit image?
Thanks!
1) Anything you draw on a layer with zero opacity will not show! You need an empty layer, not a zero opacity layer. To make this, ensure your Layers palette is visible by pressing F7. Then, at the bottom right corner of the Layers palette, beside the trashcan, select New layer.
2) To paint pixels black, press d for default colours since black is the default colour. Then press B for Brush. Now you can paint on the empty layer. Press [ to make the brush smaller and ] to make it bigger. Click the black foreground colour square on top of the square white background colour in the Tool palette (left side of my picture) to change colours.
3) To save the classification layer only, click on the eye icon in the Layers palette of the other layers that you don't want in order to turn them off. That way only the layer you want will be saved. Then click File->Save for Web and select a file format that supports transparency - i.e. PNG or GIF, but NOT JPEG or TIF.
I have marked in green, all the buttons I mention that you will need to click on.

photoshop foreground color of image cant be changed

I clicked on the foreground/background little square tool icons, selected the color I want and clicked ok. The small tool icon is showing the new color but the image itself hasn't changed the color. And yes confirmed that the mode is RGB.
You need to use a tool to apply the color as needed...
Did you use the paint bucket or brush to actually add the new color to the image?
Simply changing the color of this box does not change the foreground background color automatically

How does Photoshop show multi-layer in Normal Blend Mode?

I'm trying to understand how the normal blend mode works in photoshop.
http://www.pegtop.net/delphi/articles/blendmodes/normal.htm
As the webpage says,it just shows the color of the layer above.But when I copy the same layer and show them together,the color seems darker than just show one layer.And when I add more,the color remains at a particular value.
The normal blend mode shows the color of the topmost fully opaque layer, for transparent layers it will add from top down until fully opaque is reached.
This means that if you have a fully opaque red element over any, for example, blue element, the color red will be displayed. If you have a red element that's 50% transparent over a blue element, the color pink will be displayed.
If you have one black element that is 50% transparent it will appear as a medium gray, if you duplicate the layer, the two elements on top of each other will add up to display a complete black.
