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.
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 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?
View 7 Replies View RelatedI 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,
View 8 Replies View RelatedI 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)?
View 7 Replies View RelatedI 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).

View 5 Replies View RelatedOnce 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

Ctrl-clicking the thumbnail of the layer and editing it in the channels tab is not what I mean...
Take a gradient, from Red 100% Opacity to Blue 0% Opacity. After I saved the gradient as a PNG, how can I for example use the levels adjustment on the PNG's alpha channel?
If I open the image in After Effects there is an option to control the alpha channel. That's quite embarrassing if a video software can edit the alpha channel and an image software can't...
I've attached screenshots to demonstrate what I mean.
I am trying to select the aplha channel (and make it a selcetion ) by using the command +mouse click but I only get the black selected not the white. So i have to invert selection, which is annoying. Am i missing something? this worked 2 weeks ago and now it has changed.Â
View 3 Replies View RelatedI am using X4 and am familiar with chroma keying and setting backgrounds but I am trying to export the video with the alpha channel so I can create a flash file with transparency to use for walk on video (where the person appears in the foreground of the site with wmode set to transparent).
I have Corel Motion 3D and some of the kbase was suggesting I needed to use that to export with the alpha channel but it would be a lot simpler to be able to push it out from X4. Even if I can do it as non-flash file I can take it to something like Ijoysoft and convert to flash.
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 2 Replies View RelatedI'm developing a tile based game, I have basic ground tiles, and above these tiles can be objects. My game engine supports objects with an alpha channel, where the alpha channel is used for transparency:
alphachannel 0 = completely invisible pixel
alphachannel 255 = opaque pixel
alphachannel between 0 and 255 means the object and the background tile below that are blended, like semi-transparency.
This is useful to give the objects soft edges, and for semi-transparant fire, ghosts, and other nice looking effects. Code:
I have an image that I created in Photoshop CS3 with a drop shadow on it and transparency around it. I need to save it as a 32-bit TARGA file with an embedded alpha, so that the transparency and drop shadow work when I bring it into my video editing software, but when I save it out as a 32-bit .tga it doesn't save an alpha with it. I seem to remember Photoshop automatically creating an alpha from your transparency when you save out a 32-bit .tga. What am I doing wrong?

This is the instruction manual of the template:
------
Once you have completed the painting work on your Texture Template, be sure to save it in its original form as a layered .psd document. Then, "flatten" the image, and save as a .bmp file with the name you wish to use for your paint scheme. Example: "DFB58_N12345.bmp". This name indicates that the template is for the DreamFleet (DF) Baron 58 (B58), and the N1234 is the registration number you painted on the aircraft. If you are doing a livery for an airliner, you can substitute the name of the airline for the registration number.
The name is not important, and DreamManager will work with any name, however we suggest a logical name so that you and others will know what the texture is. With little doubt, after all this painting work, you may wish to share your texture with others by uploading it to a file library, thus, a logical name will help identify it.
With your Texture Template now saved with a proper name and as a .bmp file, it is now time to prepare the Alpha Channel template.
Re-open the .psd version of the template in your paint program, and using whatever means you feel comfortable with, copy the entire alpha channel only to a new document. Once in the new document as a standard image layer, flatten the image, convert to grey scale if necessary, and then save this file as a .bmp file, the same as you did with your Texture Template. Use the same name that you used with the Texture Template, except add the suffix "_A" at the end of the name. If you have done this properly, your alpha channel template will be the same size as your Texture Template (typically 4096 x 1024).
Example:
Name of your Texture Template: DFB58_N12345.bmp
Name of your Alpha Channel Template: DFB58_N12345_A.bmp
when a copy is made of one of the channels be it the red channel , the new channel that is created will automatically be named alpha 1, but on my photoshop it will be called red copy . Do I have to name it alpha 1 or is there a setting I have to make.
View 1 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 4 Replies View RelatedI'm using Xfrog trees (first time, and quite new to 3ds max design 2011).
The leaves are images laid onto planes. The leaf has a white background and is precreated to be transparent etc.....
In theory i should be able to import the tree, render and everything should work. it's not working. The tree renders with the white background to the leaves
Is there a setting i'm missing, maybe in the render setup?

I have a B&W images. It's actually in RGB but all shades are gray. I would like to create an alpha channel whose values equal the brightness of each pixel. How do I do that?
View 3 Replies View RelatedI'm trying to create an image which emulates a solar corona (it's basically just a blurry circle). It's as easy as making one brush stroke in gimp, but my problem is that i can't get all the channels to be correctly set.
Ultimately i just want to edit the alpha channel, NOT the RGB ones. They should all be pure white, or 255, 255, 255. But for some reason, no matter how much masking or color selection or clicking only the alpha channel and not the RGB ones or anything that i do, i cannot keep the RGB white while editing the alpha channel, every stroke that affects alpha seems to invariably affect the other three.
How can i edit ONLY the alpha channel?
Thought I'd try Gimp on my new laptop instead of Photoshop. I'm making graphics for a game.
I needed to add an alpha channel to an image and edit it, including pasting into the alpha channel from the clipboard. Easiest thing in the world on Photoshop, but seems utterly impossible on Gimp.
I've looked at a few threads that discuss editing the alpha channel, and they make it sound like rocket science. Notable, most seem to involve juggline multiple other images and then following convoluted pasting operations to get anything down. Or using layer "Masks" which, as best I can see, are impossible to paste into (and I couldn't find how to convert these masks to alpha channels either.)
As it stands, I've failed to get anything onto an alpha channel at all, except some scribble that showed up in the tiny side icon but couldn't be seen in the main image.
I'm new to Gimp, and I'm hoping I've just missed something. What is the straight forward way to edit the alpha channel (drawing on it, pasting into it from the clipboard), and seeing the results at the same time. I've tried everything intuitive and nothing works.
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?
