Paint.NET :: Adding Alpha Channel For Transparent Backgrounds?

Jan 15, 2014

what I have been doing to work with transparency: bring up GIMP to add an alpha channel and set part of an image to transparent. Save and use in Paint.net.Today, for example, I wanted to create a M + W logo, and the result looked like this:I set the font to Engravers MT, put a red W on an image.Selected "All", copied to clipboard, then pasted to a new image.Vertically flipped the new image, making it an M, changed color to blue using Recolor tool. Saved it as PNG, closed image.Started GIMP, opened the blue M image.On GIMP menu, selected Layer --> Transparency --> Add Alpha ChannelUsed Fuzzy Select Tool to select the area outside the blue MHit delete key to remove color of fuzzy selection (converting it to transparent)Save image as PNG and exit GIMP.Back in Paint.net, open the M image.Select All of Image, copy to clipboard.Paste into New Layer of W image.Adjust position of this transparent selection layer to achieve desired resutl as above.Save the completed image.I find GIMP to be very hard to work with, and prefer working with Paint.net. It would be so nice to be able to create an alpha channel and make a transparent area of an image inside of Paint.net.

Photoshop :: Alpha Channel Issue For Making Transparent Image

Jul 2, 2005

I have an image and i'd like to turn that into a transparent gif/png file for a website (has a changing bg color at random). The thing is i don't know how do this, and could use some help. What I tried so far is that I add to the original image an alpha channel which is the original image inverted, but that did not show me the checkered bg.

Anyway I added a faked impression of what i want to achieve. Thanks for any tips on how to make this work.

Paint.NET :: Color And Alpha Channel Editing In V4.0?

Oct 23, 2013

Is paint.net v4.0 still promising color and alpha channel editing / masking?
 
I'm sure I read this in the roadmap feature list years ago, though I can't find the place to reference it. In fact this is my favorite anticipated feature for which I've been checking paint.net every month for the last five years!
 
I eagerly downloaded the 4.0alpha but see no sign of color channels to go with layers

Paint.NET :: Adjusting Alpha Channel Levels?

Mar 10, 2012

I have an image I want to edit. It is a png tileset for a game, with opaque icons with semi-transparent background (yep the result in game is just as annoying as it sounds).

I'm not satisfied with background and want to make it more transparent (or maybe completely transparent). How do I do that?

There are adjustment tools in PDN that can modify separate channels; AFAIK alpha is technically identical to color channels but these tools only let me edit RGB.

how to specify a layer as alpha mask either.

Paint.NET :: Load DDS File With Alpha Channel

Feb 19, 2011

Is there anyway at this point in time to load a DDS file with alpha set to something other than 100%, alter the alpha channel, and save it back out again?

My situation is this. I'm currently working on a module for a game called Mount and Blade Warband and have created quite a few textures using Paint.net and never had any issues previously with any textures I've created and saved as DDS. However recently I found a texture file that I need to replace with my own version which has it's alpha channel set to something other than 100%. It's used to blend with another texture to give an aged appearance to hair.

Now this texture when loaded into Paint.net appears as a mostly transparent texture, which I cannot make any darker using the layer transparency slider which is set to maximum. i.e. The texture is loaded and displayed with transparency on, but the layer transparency slider in Paint.net is set at maximum opacity as if there is no transparency -- so the only thing I can do is make it even more transparent rather than make it darker. So when I tried to make my replacement for this particular file I created my texture, set transparency for the layer to about 20%, then saved as a DDS file -- however when I load it into the BRF game editor it displays as a completely black texture, while the original file displays fine.

EDIT: Also does it actually create mipmaps when you ask it to when saving? I just noticed that my textures don't seem to have them.

I should point out that while I'm very experienced with programming, 2D etc. I'm pretty new to 3D programming (not that I'm doing so on this project of course -- thought it might be easier working out how to create 3D objects while using someone elses engine to start with) and 3D object creation -- so things like DDS texture formats still create a lot of head scratching.

Paint.NET :: Choose The Type Of Alpha Channel?

Paint.NET :: Add Black Alpha Channel To DDS File

Apr 9, 2011

In photoshop there is a tab beside the layers tab, that allows you to add a shaded alpha channel to a .dds file.

I need to add a black alpha channel to a .dds file.

I've tried every alpha pluggin I can find but cannot replicate this effect.

And if I open a .dds file created in photoshop with a black alpha channel it is completely invisible in paint.net.

Why is it completely invisible in paint.net but not in photoshop?

How can I add a black alpha channel to a .dds file in paint.net?

Paint.NET :: Pasting Normal Map Into Alpha Channel

Nov 18, 2013

If I have two images, one is a texture map and the other is a normal map, how do I essentially paste the normal map into the alpha channel?

The stuff I am importing into (OpenSimulator) uses a single image to put texture and normal map information onto an object but so far I can't see anywhere to create the alpha channel.
 
I am not using the alpha channel for transparency, which seems to be a source of confusion (elsewhere). The thing is I CAN use it for that (transparency I mean) simply by making part of my image transparent (This is splendid by the way, and is yet another reason why I adore Paint.Net), this implies to me there are alpha channels or that the transparency thing is something different.

Paint.NET :: Black And White Image - Use As Alpha Channel

Paint.NET :: Proper Alpha Channel To Eliminate Border

Apr 13, 2011

PDN is an amazing tool. The issue I'm having is that when I try to create a partially transparent texture for use in Unity 3D, I get a gray border inside of Unity that is not visible in Paint.net. It appears to be a well-known issue, and there are lots of instructions, video tutorials, etc. for how to deal with the problem when using Photoshop.

See the following post for more information: [URL] .....

The basic theme of the solution is that you need to create a "proper" alpha channel and not rely on the "checkered background" that exists in Photoshop. Is it possible to achieve the same thing with Paint.net?

Paint Shop Pro :: Transparent GIF And Web Page Image Backgrounds

Aug 19, 2012

I just purchased Paint Shop Pro X4, and do have one question about making transparent images.

I’m designing a simple, basic text-only logo for my web site. I know how to make the image transparent. That’s not a problem, if I'm using a plain solid color as the background of the page.

What I would like to know is this: How do I make the text logo transparent if the page background of my web site is an image, such as a photograph, or textual wallpaper. I’ve never tried that, and am wondering if that will make the creation of a transparent GIF more difficult.

Is the procedure for making a transparent GIF different in this case? If so, what steps should I take?

Paint.NET :: Unable To Make Photo Backgrounds Transparent

Dec 12, 2012

I have been removing photo backgrounds, saving them as .png and using them in a Power Point Project. Apparently when I reopened that PowerPoint project to add more photos, Libre Office's Impress  opened the .ppt file rather than PowerPoint. When I had added all of the png photos and saved the ppt file again I saw that it was "Impress" not PowerPoint that was saving he file, but it still saved it as a ppt file.

I was not concerned until I went to open the ppt file with PowerPoint and discovered that PowerPoint could not open that ppt file. I decided that I had to start fresh and add all of the png photos in a new Pow1erPoint Project. Then I found that he transparent background ol all of the png files had been changed to black. I must have transparent backgrounds. So I took each photo back into Paint.Net and used the Magic Wand to remove the backgrounds, then saved them as png files. When I sent to use those edited .png files the backgrounds were still black. I have tried removing those black backgrounds several times but they continue to have black backgrounds.  what I can try to get the transparent backgrounds back?

Photoshop :: Alpha Layer Vs Alpha Channel

Sep 5, 2013

any difference between alpha layer and alpha channel? I mean has to be right? I just don't know what exactly that would be if there is. I'm trying to figure out some more stable uses for computer graphics when building textures with alpha layer or alpha channels. So far I get a flicker from opengl bug when using alphas. So I'm wondering if I use Alpha layer and something with a solid color underneath the geometry if I could achieve a more stable result where alpha sorting. Possibly clearing it up where my alpha layered geometry stays on top vs bleeding through at times it seems.

Photoshop :: Alpha Channel

Jul 28, 2006

I have created two masks with channels to use on an image. Now I want to combine the two channel masks into one to use. I made a new layer in channels of the composite masks which gave me an Alpha channel. The Alpha channels show the solid black paint lines where I filled in the selection voids. These solid lines affected the adjustment layers so I ended up doing some erasing at 50%. Not the shortest workflow direction. How can I combine two channel masks (selections) into a common selection and save as a new Channel?

Photoshop :: Alpha Channel

Nov 25, 2004

I created an alpha channel with marquee tool on a colored backgound, by using "select > save selection", the alpha channel appeared at the bottom of the channel palette. I know the white part should represents transparency and the black part is opaque. But when I import this into the Adobe premiere6.5, the thing is reversed, I have to use "alpha channel" plus "reverse" option to get what I want - see through the "white" part. I heard there is an option in the photoshop with which you can define whether you want "white" is transparent,black is opaque or vice versa,

Photoshop :: Alpha Channel Even Though It Isn't Used At All

Oct 1, 2005

I have an image that I want to have an alpha channel even though it isn't used at all. Even if I save the image with transparency flag in "Save for web" (as PNG), Photoshop doesn't include the alpha channel with image because it's not been used. Is there a way I can overcome this (other than adding a single transparent pixel to image or using another program)?

GIMP :: How To Add Alpha Channel To 24 Bit PNG

Aug 12, 2013

I have a 24bit PNG image to be used as a texture in my little game. I want to blend this texture with other colors which require it to have an extra alpha channel. I did some search online and tried some methods including add another layer and add transparency to the image, but neither worked(after I exported the image to png and reopened it, it still only contains 24 bits for every pixel).

Photoshop :: CS5 - Editing Alpha Channel

Aug 3, 2013

Once I create an alpha channel, how do I edit it?  I have tried selecting and clicking the alpha channel, and then using the paintbrush tool.  I understand that if I have a white foreground, painting should remove some of the mask, while a black background should result in the painting adding to the mask.  But often nothing seems to happen when I paint.  Or, at other times, the painting results in paint marks on my image but doesn't affect the "marching ants" and therefore doesn't affect the mask. I have already checked that my K setting in Color is at 0 for white and 100 for black.  Using CS5 version 13.0 x64 with Windows 7.
