I was wondering if someone could help me create a PNG that when overlayed on an image only shows when its on top of black. ie the image underneath is black and in some spots there is color. Wherever there is black I would like the overlayed png to show. Wherever there is color I would like to the overlayed png to be transparent.
View 2 RepliesI'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:
transparency and alpha channels. I'll explain what I want to do, and hopefully someone can tell me how. I'm creating an image in a 3d modeling program. I want to export an image file (Targa, 32 bit, with Alpha Channels) into photoshop, then extract the alpha channel(that being the black background in this case) so that i'm left with the actual image of the 3d model over transparency, with which I can use to layer on top of things created in photoshop. Ok, that said, i'll explain it one more way, in hopes to make it clearer. I'm doing weather graphics for a news program, and have rendered out a cloud in a 3d modelling program(3d studio max). I want to import this image of the cloud into photoshop, and layer it over graphics I created in photoshop, minus the background created in the exporting from the 3d program.

View 4 Replies View RelatedI'm trying to do something that I could previously do with other image software. I want to 'paint' the transparency of a layer using the alpha channel. So when I paint black on the alpha channel it makes that part of the layer completely transparent, and white makes it completely opaque (and grey shades are in between). From what I understood of the help, this should be possible by just creating an alpha channel and painting in it. But when I try and then click back to display the RGB channel to look at the changes I've made, nothing actually changes. Whatever I seem to do to the alpha channel it doesn't actually affect the layer's transpancy at all.

I would save png after that.
making a alpha channel transparency; Funny thing is. I made it work once a few days ago. I went to bed and forgot to write down how i did it (Tried everything, almost)
In the link right here [URL] n i have 4 files; Q3a_arrow_gimp_ver4.tga (TGA that works as i want it, you'll notice ALL the alpha channels have a black layer channel in the channels tab, how do i recreate that?) Q3a_arrow_methodtry.tga (tried to recreate with THIS tutorial [URL] with no success P.S. i tried loooads of tutorials but this recreation seems rather close to the working .TGA i need) Q3a_arrow.ai (sourcematerial all vector from Adobe Illustrator) Q3a_arrow.png (picture with transparency intact if needed for comparison)
So; Now... What i did to make the working picture was making a .PNG - drag it into gimp.. I recall doing some Alpha and or masking or selection thing with it, then rendered it for .TGA since Illustrator does not support the kind of .TGA i needed. Worked flawlessly in the engine where i use a function called alphafunc GE128 (blend with black as invisible layer and white as solid)
In 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 think this is related to Xara's inability to export alpha transparency properly. I've talked about this before, somewhere. Feel free to find the old post.
The thing is, without a decent export the feature is largely useless isn't it? .Xar is almost never the destination format.
I can get round the edges issue by printing to PDF instead of exporting, but then the bounds of the original bitmaps are visible. So neither solution is any good at all. Surely this is a massive problem?
png texture with alpha channel but the transparency seems to be white.
How do I let the transparency in the png texture look through to the background?(alpha blend)
Basically, I am trying to use an alpha layer/channel to export a picture that is transparent except for a grass clump that is colored green over the alpha layer. So the picture looks like a solid green rectangle, but is actually a green blade of grass.
Problem is, I cannot get the alpha layer to work. I can't follow the tutorial as it is in photoshop, and random videos on-line haven't worked.

I have removed the background from a photo using selection deleting to transparency via alpha channel. My dog was left. I then exported to png. When I try to upload the dog to use in a label, (Open Office), the back ground turns to white.
What am I doing wrong?
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?
I already have an image file in png format..which I want to use as an application launcher icon for my android application.
The android specifies image with following properties for the launcher icon(Will need 4 different image to support different screen size in mobile devices)
Launcher icons should be 32-bit PNGs with an alpha channel for transparency. The finished launcher icon dimensions corresponding to a given generalized
Screen density are shown in the table below.
1. 36 * 36 px
2. 48 * 48 px
3. 72 * 72 px
4. 96 * 96 px
I would like to create 4 png files(with specifications mentioned above) from the already existing image file. How do I do that in GIMP.
I am completely novice to image editing(Never touched any image editing software before) and not sure how to achieve this in GIMP.
The problem: I am importing a PNG sequence into After Effects (CS 5.5), however AE refuses to see the Alpha channel contained within the sequence. Now before anyone jumps the gun and says, "But wait, PNG does not really support alpha, it just supports transparency!" Right, something I just learned, and still -- quite honestly -- baffles the heck out of me.
But anyway, another PNG sequence exported from the exact same program, imports into After Effects just fine with an "alpha channel" and all. I double-checked, and there is NOT an option in the program to export the PNG without transparency info.
Importing sample images from each sequence reveals the EXACT SAME THING ... both have transparency, but NEITHER have an alpha-channel per se.
1) why in the heck AE would interpret one's transparency, and not the other?2) Is there a way to FORCE AE to see the transparency of the one?3) IF not, is there something out there that will convert the PNG's with transparency to another format (TIF, TGA, PSD) with an alpha? I just don't want to have to re-render the sequences again.
For quite some time I've been trying to find the best way to remove a white background from images. I've checked out the sticky thread on this forum and as my image isn't of great quality and because it features quite a lot of white that won't apply.
Recently I found this tutorial which is supposed to work great (as seen in the comments). However, I think that because of a GIMP update that won't apply anymore somehow. I was hoping you guys might know what was causing it.
Everything works well until I get to step 7, where I have to select to Alpha. There it selects just the outlines, but my selection includes inner parts of the image, not just the background. And then after I invert and delete, the white that remains still has transparent parts that show up on the upper layer. So, am I doing something wrong with the Alpha to Selection, is that tutorial updated or is there a better way to remove the background from ie. a logo with just one background colour which isn't of great quality.
Basically just want to make the middle separating line in the following image:
Identical to (same degree of horizontal fadeout into transparency):
I have spent hours on it trying to edit the original layer below the alpha transparency or adding layers, getting nowhere.
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?

View 1 Replies View RelatedThis might be a really obvious question, but I was wondering... If I was to have a rectangular object or something... how could I apply a gradient of sorts that makes it starts completely solid, but gradually becomes more and more transparent?
View 7 Replies View RelatedI'm an beginner/intermediate Photoshop user, using CS5. I'm working on an image of two women, starting from an historical photograph. I selected, copied and pasted the central image of the 2 women onto a new layer which is otherwise transparent. I then created a copy of the original photograph's layer and applied a masking layer with a radial transparency gradient, so that when the original layer is hidden, the background appears to be radially faded behind the central image. So far, so good.
However, I'd like to apply an additional "dose" of transparency around the edges, so the image fades completely at the outermost edges. And I'd like more control over this additional fading than just applying another gradient.
I've seen a video of someone "painting" transparency onto an image, but I can't quite get my brain around it. From what I've read, it looks as though I should create another layer that will be an additional masking layer... but how to do this.
My undying gratitude for any assistance to get me past this roadblock.
I am using the new Creative Cloud attempt from Adobe. In 6 months, the only consistent documented behavior from photoshop around transparency gradient adjustment layers is to deselect all layers and then select just one layer to use for the failed Photoshop transparency effect.
I have not found any tutorials that I can duplicate on my machine. Either the tools will not appear 99% of time, or when they do 1% of time they do not work as described, work erratically, or do not work at all. I have got the CC Photoshop to perform a linear gradient from layer to black background. That is all CC Photoshop can do consistently for me. For multi-step tutorials, the steps are consistent, but CC Photoshop popups and resutls literally change with each gradient attempt. Freaky application failures. 100% of time CC Photoshop fails, applying the gradient from an object in foreground to a black background.
Layer foreground to black background must be the default. Anything else fails and is highly erratic. It is as if this CC Photoshop is intended as a supplement to whatever they are using in the tutorials. For example, If I had the money for a full Photoshop CS6 box, everything would work fine? CC Photoshop is a total fail on this computer. Adobe telephone support results the same failure. I am always going to get a call back "with a resolution". but the callback never comes, or it comes with the excuse "we are working on this". All I want is a Foreground to Background transparency gradient for a selected layer... ever since the CC beta trial appeared a year ago. For example, how do I create a radial transparency gradient using CC Photoshop?
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.

View 8 Replies View RelatedI'm sure 'variable transparency' is not the right way of putting this.
I have an image which has some text in white. However because of the aliasing the text is not 100% white against the background (black). Rather; the edges are shades of white.
I want to convert the image so that the text is transparent. If the text was 100% white it would be simple. Colors.. Colors To Alpha. However that doesn't work as it doesn't deal with the shades of white around the edges of the text.
I want the shades of white to be transparent with the same degree of opacity as they white. So the white in the image is 100% transparent and a pixel which is say light grey to be 90% transparent. (The end image is going to be used as a webkit mask; showing the background behind the masked element).
I don't know where to start with this. I know PNGs support 8 bit transparency so it should in theory be possible.
I have a circle with split into 5 segments (image A).All of the segments have a stroke (1px) of white, and a fill.
What I want is for the STROKE to be transparent so that when I position the 5 segments over a different background colour (image B) I see the colour underneath where the white stroke would otherwise appear. To recap - I would like to retain the width of the stroke, and make the stroke coloue transparent..
I've tried the Opacity setting, but this applies to the object, not just the stroke.
With transparencydisplay=1 I create hatch with transparency (for example) 80%, I save file and I close it. When I re-open the same file hatch have transparency 0%. What's the problem?
