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'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.

View 1 Replies View RelatedI have a series of files in which I improperly modified the selection set prior to saving the selection, and now around the intended viewable area there is a hazy artifact that seems to correspond to where I manually edited the selection using Quick Mask (prior to saving).
In other words, within the area of the alpha channel that should be invisible, there is actually a visible, unwanted grey-ish artifact, and I think it's related to how I was using the brush to edit the selection in Quick Mask before saving.
Now I am unable to edit the alpha channel, although Adobe's own website says that in order to edit an alpha channel, all I need to do is select the alpha channel (which I am doing) and then paint at 100% black or white with a brush to either include or exclude parts of selection set.
When I choose the brush and start painting at 100% black or white, nothing happens and I can't figure out what is happening.
The exact steps that I'm taking are below:
1) click on alpha channel (visible and ready for editing), all other channels only visible not active.
2) selecting the brush at either 100% black or white
3) attempting to paint to alter the alpha channel (I've tried painting on the actual alpha channel in Channels, and I've tried painting on the alpha channel as it appears in Layers, and neither works for me).
CLARIFICATION:
I actually am able to "edit" the alpha channel HOWEVER I cannot remove the hazy artifact. I can use 100% black or white to remove the pink/light red areas on either the actual alpha channel (in the Channels area) or as it appears in Layers, but I cannot remove the areas that are grey-ish (well I can paint them white but I can't paint them black, i.e. fully pink).
A teacher showed me a quick fix process that basically involves activating the alpha channel, inverting the selection, and then deleting everything outside of the alpha channel, and then resaving the file. That worked at one point, but now that quick fix is not working either (I am just ending up with a completely visible, white space around the intended visible area, rather than an invsible area).
EDIT (07:22 3.20.13) Also, if you look at what Photoshop is registering as the actual alpha channle, it doesn't match with what I'm seeing above, that is the black and white alpha channel appears to be as expected, and there is not the weird distortion that I'm seeing above in the pink/grey image.
Saving selections and alpha channel masks?
View 2 Replies View RelatedWhen I save a render as PNG and then open it in Photoshop, it doesn't have the alpha channel, just R,G & B channels. The PNG Configuration Setup when saving the image has of course Alpha channel box checked, but is not available when I open the file in Photoshop.
Note: I was able to do this in 2008 version.
I thought that I could just use Quick Mask to manually paint with 100% black or 100% white to adjust the boundaries of the selection and then save that final selection as my alpha channel.
However, I'm discovering that when I do this, I end up getting a weird grey-ish artificat (which incidentally, I can't figure out how to remove it). How I should be properly modifying the selection prior to actually saving it.
One project I use Photoshop CS4 for is painting aircraft used with Microsoft Flight Simulator X (FSX). Each aircraft is downloaded as a "Paint Kit".I paint and add layers onto the kit until the aircraft resembles the design I chose. The paint kit includes a background, base parts usually in white, and an assortment of layers adding physical wear, shading, lines and rivets you see on actual aircraft.
Additionally, the kit includes an RGB Alpha Channel and Specular Maps. In this application, the Alpha channel provides the reflectivity or gloss on the aircraft paint. The Specular maps provide a sheen much like the subtle reflections you see from a metal flake paint job when the sun hits it directly.
Once all painting and manipulation is complete, the kit is "cut" into specific sizes. Once the kit is cut, each section is saved as a DDS file using NVidia tools. The resulting DDS files are placed into folders within the main FSX program folder. The FSX program "assembles" the sections and processes the different layers and channels resulting in aircraft that are incredibly detailed and realistic.
My problem is I don't know how to properly integrate and preserve the Alpha channel during the "Flatten Image" and when saving the file as a dds file. As you can see in the "Layers" section in the picture, the Alpha channel is already made. I just don't know what to do with it to preserve it and ensure the reflectivity it provides is visible in the final product.
what I need to know isn't what the alpha does, but how to properly integrate it into the final product. I've searched for this info for the last several days, but I've had no luck in finding specific information on how to do that. URL....
How do I take say the black and white version of an image and use the final grey scale value as the alpha value for that pixel on the original? Is this possible to do easily?
If not, what's the hard way?
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
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.
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 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?
Win 7 64 bit
PSP X5
i have just edited 70 photos using capture editing and apply editing, and have all of them stacked up on the screen.
Can I automatically save them all without having to save each one manually? I tried using the same method as above but it did not save them.
I am unable to select Alpha Channel from the Options button when saving image to PNG file. see screen capture.
I want image only- no background.
Programme: X4
System: Windows 7 Ultimute 64bit
Installed 01/01/2012 with SP1.
Problem: When I save jpeg files some of them become corrupt and will not open.
I have been using PSP for a number of years and decided to upgrade to X4, now a number of the files that I save in PSP are becoming corrupted and they seem to all be photos which are shot using a pure white background, not all photos are affected, I never had this problem in my previous versions of PSP
I use adobe lightroom which I transfer my raw file into jpeg, this is where i then open the jpeg in X4 and do my main editing, it is when I save the image it saves corrupted and can not be opened or deleted (shows that X4 is still using the file) . it will also not allow me to re transfer the image from my catalog.
There are some good features and I am considering uninstalling and reverting back to my older program (X2).
This may be an issue with the metadata of the image, I exported 2 sets of 50 identical images 50 with and 50 without the Metadata and ran a script which then automatically save the image, about 20 of the images with the metadata ended up corrupted, all the images without the metadata saved fine.
I'm testing the new People tagging feature... organizing and searching seems to be no problem at all... My question though is whether this "tag" information is saved back to the actual files themselves, or whether it is kept separate in a corel database file??? i.e If I reformat my harddrive and then reimport my pictures, will the photos still have their tags!?!?! (photos area stored on a different networked drive)
The "date modified" data of the file has not changed after tagging... I only want to use this feature if the tags can be permanently written to the files.
I think I've found a major issue with saving .PNG files that have partial transparency in PSPx4
Essentially any opacity isn't saved correctly, and is made far too transparent. So anything with partial transparency is saved incorrectly.
I first noticed this when I saved a file to PNG that had a drop shadow - and the shadow seemed to have not been saved. In fact it had but the transparency was now so much higher it was almost invisible. Looking closer, all partially transparent pixels are not saved correctly.
This issue isn't present on x2 and PSP 9 (two old versions I've got).
I've done a simple test. Create a new image, transparent background. Fill with a colour at 30% opacity. Save as PNG, save as PSPImage. Resulting PNG looks completely different to the PSP image.
See the below screenshot, and also the but saved as PNG in PSP 9 (to show this is fine).
I'm always saving to PNG and this makes PSPx4 useless to me I'm afraid. I've checked the save settings and it's the same as PSP9.
im trying to add an alpha layer or alpha channel to a bitmap and save in BMP format.
I am using Photoshop 6.
can someone tell me the easiers way to make an alpha tga file? Photoshop 7 can done alpha when i save to tga 32 bits, but in CS we have to do it manually...
View 1 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 RelatedIn PSP 8 I made a circular white clock face with black numerals on green background. I then saved it as a PNG, specifying the green as the transparent colour and specifying alpha channel.
It worked OK when viewed in my video editor, i.e. the green was transparent. But on opening it in PSP 8 I expected to see it displayed with the familiar chequer board background, yet it was a solid white.
So among many other PNGs it's impossible to tell that it does have a transparent area. Is this also the case in less ancient versions? What about other image editors - do they all have this weakness?
I get the idea to save my processed RAW files in jp2 jpeg 2000 16 bit format(channel) so they need less space as RAW or tiff and can be later good modify without noticable quality loss. But i get the requester, that the format support only 24 bit ( 8 bit/channel)
jpeg 2000 is here since 10 years. Is it not possible that windows or other programs can read 16 bit /channel files, or whats the reason wy it is not possible in PSP X4 upd 1 to store such files ?
Does other programs too not support 16 bit /channel jpg ?

View 1 Replies View RelatedI 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?
