GIMP :: Batch Process - Decompose Alpha Channel And Save

Nov 6, 2013

I have a series of images with alpha channels what I want to separate out from the images and save as a new file with a filename suffix.

For example I have a series of folders containing thousands of images:

These files are filename.dds files (I already have the .dds plugin to read them but you could use .png for example).

I load the image, goto Colours - > Components - > Decompose :

In the dialogue I enter color model : Alpha, tick decompose to layers - > OK

I then export the file as filename_a.jpg

Is there a way to batch this process for the 1000's of images I have?

Photoshop :: Batch Process: Add Alpha Mask From File

Aug 9, 2009

I did a search for this, but couldn't find anything.  If there is something, please feel free to send me in that direction. I use Photoshop a lot for my 3D work.  Usually, when I render an image sequence out, I have the mask saved in the alpha channel.  Unfortunately, ZBrush doesn't allow me to do that, and instead saves the mask out as a separate image.  I need to add the alpha mask to the color plate file.  Is there any way to do this with batch processing?

Photoshop :: How To Save PNG File With Alpha Channel In CS5

Aug 22, 2013

I have a PNG file created in Photoshop and I need to save it with an alpha channel for web purposes. I tried 'Save for Web & Devices' and selecting the Transparent box.

Then, after saving, when I select 'get info' for the file it says there is no alpha channel. I'm stumped I can't seem to create an alpha channel from within Photoshop while I'm editing.

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).

GIMP :: Edit Only Alpha Channel

Nov 9, 2011

I'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?

GIMP :: How To Add Alpha Channel To Image

Jul 24, 2011

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.

GIMP :: Direct Editing Of Alpha Channel

Mar 21, 2012

Is 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.

GIMP :: Add Different Information Into Each Channel Including Alpha

Feb 26, 2013

Basically I need to be able to add different information into each channel including the alpha without the image being transparent at all.

Not to compare at all, but in photoshop i could work solely in the alpha channel without the RGB channels visible, then enabling the RGB channels would allow me to see the entire image without any transparency.

Basically, i want to be able to use the alpha channel for things other than transparency. For storing different masks in each channel for use in shaders.

GIMP :: Unable To Unlock Alpha Channel

Dec 18, 2013

I started using gimp yesterday to remove backgrounds out of images for my website so have done it fine.

But now I clicked on something which reduced the toolbox dialog box to not be as large - ie it does not show you pixels size etc if you select pencil tool now.

Also I open an image and lasso it - then click the quick mask but the pencil tool is not adding any more to the area - it wont draw over or anything. The lock alpha button is on in the layers panel and I cant unlock it.

GIMP :: Set All Pixels Below A Level As Alpha Channel

Jul 22, 2013

1.I am working on a project where I need to set all pixels below a level as alpha channel, is there a quick way to achieve this? The level can be both set a prior or adjusted dynamically, the second way is preferred. Right now my workflow includes:1. duplicate layer.
2. use color level in duplicate layer, in menu COLOR -> LEVEL.
3. add alpha mask to original layer
4. copy duplicate layer into the alpha mask of the original.
5. delete duplicate layer.
6. If result is not ok then return to 1.As you can see this workflow is a headache, specially point 6 which is often achieved.

GIMP :: Copy / Paste Alpha Channel - Texturing

May 18, 2013

I have some textures, and i am trying to pack them into texture atlas. All of them are RGBA png's generated with PIL (Python Image Lib). I am opening all of them in gimp and copy-pasting them into their new place in texture atlas.

But i have noticed something strange, i am storing specular map in alpha channel of my diffuse textures, and emission value in alpha channel of normal textures.

The problem is, that GIMP does not copy pixels with 0 alpha value into clipboard. So, when i am trying to copy a normal map from source to atlas, and if emission value is 0, then GIMP is not copying anything, i am getting empty layer pasted into my atlas, if there are 0 alpha value pixels in diffuse map they are not copied to destination, even selection outline shows that there are no pixels in places where specular is set to 0.

GIMP :: Bucket Fill Effect On Alpha Channel

Dec 17, 2010

I have a PNG logo that has anti-aliased letters on a transparent background. In other words, all pixels are white (for example) and either 0% transparent (in the letters) or semi-transparent (in the anti-aliasing). The rest of the image is transparent.

What I'm trying to do is take change the color of the logo. Bucket fill in normal mode changes the alpha value of the semi-transparent pixels to 0% transparent when applying the color--so I loose the anti-aliasing. I did manage to get what I want with bucket fill mode Darken only, but this only works for certain colors on certain other colors (I can change white to any other color, but not vice versa).

Is there a straightforward way to fill a color while keeping the alpha channel intact? I tried all the modes, and also modifying the Fill transparent areas, but don't really understand them to figure out if one does this in the general case.

GIMP :: How To Perform Basic Editing Of Alpha Channel Layer

Dec 26, 2012

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?

GIMP :: Make Grayscale Image Into Alpha Transparency Channel

Oct 21, 2012

Is there any way I can directly make a grayscale image into an alpha transparency channel?

I mean, NOT involving selection? Because selection by color to layer mask,is really difficult what I need to do the selection threshold.

Why is it easy to turn an alpha channel into a grayscale image but not the reverse?

GIMP :: How To Make Black And White Alpha Channel For A Video Game

Jan 31, 2013

I'm trying to make a texture for a model in a video game, and I want some of it to be transparent. This is done by editing a text file that tells the model to use the textures alpha channel. things in the alpha channel that are white are transparent and things that are black aren't.

But I don't really know how to edit the textures alpha. Here is a video I've seen that explains how to make one in photoshop: [URL]......

Jul 17, 2013

I have a set of actions i need to run on a couple of hundred jpegs, they simply need a lens correction, auto colour and auto contrast, then need saving as tiffs, all works fine when i record the action, but when i run it on a folder full of jpegs, the tiffs are huge! original jpegs are around 5mb and the tiffs are 30mb, if i apply the save as to a file individually it seems fine (file size around 2mb)

In the save as section i have specified jpeg compression at a quality of 8, but it seems to miss this in the batch process, am i missing something?
