Is paint.net v4.0 still promising color and alpha channel editing / masking?
Â
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!
Â
I eagerly downloaded the 4.0alpha but see no sign of color channels to go with layers
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.Â
View 2 Replies View RelatedI am looking for a mean to edit (not create and then edit) an already existing alpha channel in a PNG file (for example). Here is the scenario: load a PNG file with a existing transparency layer created with some other application ( I see the usual checker board behind some transparent regions of the image)select a region ( lasso, rectangle, ....)change the transparency (alpha) of those pixels only, do not change anything else in the reste of the image (ex: make a region more transparent or more opaque). I do not want to edit the RGB content of the pixels, I want to edit their alpha value directly.save back the file to a PNG file with modified alpha value.
View 36 Replies View RelatedIs it possible to directly edit the alpha channel? I need to edit it for a 3D model I've made, and its showing up as too shiney (The engine is looking at the alpha for reflectivity).
However, I have yet to see a way to edit the alpha channel directly.
I've made a short animation that I want to use in my video project created in Final Cut Pro.
I need the video to have an Alpha Channel.
The animation is a Lower Third to put titles on.
how I do this.
and how do I export the file?
For years I've been using various image editors, often in combination. That is, I do simple stuff as copy / paste and repositioning of elements in one editor and subsequently open the image in a more advanced editor for proper paintwork. Currently I'm using the Gimp for the latter. Color layers work brilliantly. However, I have big problems with my alpha channel--I've found no way to edit it within Gimp and I've found no way to import a revised version that I've edited in another image editor. There must be solutions to both challenges.
The editing I require is piece-of-cake in basic image editors--I simply want to move a transparent region a bit to the left. That should be a simple rectangle selection and then shoving it (mouse or arrow keys) to where I want it. Alternatively I could import my edited alpha channel image as I'm used to doing in other editors. Well, the Gimp will accept the image as a layer all right but I haven't succeeded in making the Gimp import my grayscale image as an alpha channel. I get a grayscale non-transparent layer instead.
So, I've got a perfectly good alpha channel that needs a minor tweak. It loads as intended in Gimp. How to perform basic editing of this alpha channel layer or tell me how to import a revised version and tell Gimp that this image should be interpreted as an alpha channel?
I've seen instructions to use this but I'm not sure what its core purpose is and I can't seem to find a definition in the user manual, online or in this forum.

If not, what's the hard way?
I creat an alpha channel it shows up as white on my Photoshop Version 6 while my friend's alpha channel comes up in black on Photoshop CS. Obviously each is a default setting. How do you change the alpha channel color from white to black and vice versa.
View 5 Replies View RelatedI 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.
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.
Can you choose the type of Alpha channel that Paint.NET saves? Premultiplied or non-premultiplied/straight?
Otherwise, what is the type of alpha channel that Paint.NET saves by default?
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?
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.
I'm using the 3D render engine vray, using its multimatte render element which assigns mattes of certain materials (or objects) in the scene to a channel: R, G, or B.
Â
I'm curious about the best way to composite once I have this file rendered out. The simplest way I can think of is doing a color range selection on the matte channel's solid color, then using that selection to modify my image as necessary. But I have used After Effects to do this also, and there is a "channel select" effect that extracts the channel and converts it to an alpha mask in one step... makes me think there's a more elegant way in Photoshop as well.
Confirm that the alpha channel is not saving correctly for TGA files using PSPro X4?
1 Create an image with an alpha channel.
2 Save image as a TGA.
3 Close and re-open the TGA then load a selection from alpha channel.
I was simply wondering the best means in Paint.Net to use a black and white image and use it as the alpha channel of my image, with white being opaque and black being fully transparent. I looked through the plugins on the site and didn't see anything that seemed to resemble what I was after.
View 2 Replies View Relatedwhat 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.
View 3 Replies View RelatedPDN 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?
This question is more theoretical, as I have found a work around. On a layer, I have a gray color, which I sample, and it becomes the desired Foreground color.
Â
I would like to Fill a Selection in an Alpha Channel with this gray color.
Â
However, when I view the Alpha channel, my forground color is lost to black/white, which I understand, as the Alpha channel is a gray scale image.
Â
But, I am able to sample a gray Swatch to make a Foreground color, but how can I preserve my chosen Foreground gray selected from a Layer? The only way that I know would be to make a new Swatch, and then use that when I am in Channels.
There seems to be tons of threads on how to make a transparent image, but I haven't been able to fine one to do one specific thing.
How do I set the alpha channel to be black? I want to have a black background on a png file, but I need the black to be transparent to things behind it on a webpage.

View 6 Replies View Relatedany 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.
View 4 Replies View RelatedIt's not really related to Paint.NET usage, but how it calculate the resulting color:
Â
For example I make red background, call it C1:
Â
RGBA = 255, 0, 0, 255
Â
Then I place a yellow pixel, call it C2:
Â
RGBA: 220, 216, 0, 200
Â
Then I use the Color Picker tool on this pixel, I get C3:
Â
RGBA:Â 227, 169, 0, 255Â
Â
I already know how to calculate R, G, and B of C3
Â
R = ( (C2.A / 255) * C2.R ) + ( (1 - (C2.A / 255)) * C1.R ) = 227
G = ( (C2.A / 255) * C2.G ) + ( (1 - (C2.A / 255)) * C1.G ) = 169
B = ( (C2.A / 255) * C2.B ) + ( (1 - (C2.A / 255)) * C1.B ) = 0Â

But for the Alpha channel, it is different and I can't find how to calculate it!
