I'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'm attempting to write a batch script to add some layers to a pre-existing image and save a copy. I've gone through the tutorial, and have run the demo code from Basic_Batch with no errors, but my (what I think of as simple) script throws an "Error: eval: unbound variable: ?" It also seems to cascade the error to other scripts, as I then get "unmatched parentheses: 2" errors from what I assume to be the script immediately following my own during Script-Fu load. This occurs whether running from batch or clicking "Refresh Scripts" from the Script-Fu menu.
What I could find on this forum and Google suggests that I may be required to 'define' one or more of my variables before using it, but for the life of me, I can't figure out which one that would be, and the error (reporting that '?' is undefined!?) I've quintuply (probably more ~_^) checked my parenthesis matching, but they look fine to me.
In case this was an encoding issue, I've tried saving my .scm file as both UTF-8 and ANSI. I should also note that I'm running Windows 7 x64 in English-US.
I am deciding to switch over to gimp from pixelmator because of the extra features. However, there is one thing that is making me concerned is some limitations in the filters.
How do I create a checkerboard pattern (using the filter) which has a green color for its primary color and transparency for its secondary color? In pixelmator this is easily done because there are extra color pickers in that filter supports transparency, so no problem. However, this isn't the case in gimp.
Is it possible to create a database resident system variable? My desire is to create a system variable that I can use to expose results of my program, and/or let the user set values that the program can use.
I'm on the brink of insanity with creating my diagonal line pattern. I've tried everything I can think of but the pattern is an absolute mess! I want to create a diagonal line pattern but I want the lines not to be uniform. Basically I've made a group of 3 lines and then one separate line on its own, then to repeat this as the picture below. I've used the distribute function so the distances between the lines is identical everywhere. I've then rotated the whole thing exactly 45 degrees and aligned the lines to fit the bounding box in the "make pattern" mode as shown. Yet the resulting pattern is just a mess of overlap ugliness. All I want is for the pattern to literally look as it does in the image on the left, how to sucessfully do this in CS6?
My problem is it's in its own menu under Filters and I would prefer to have it under Light and Shadow. So I open the script using Wordpad like I've done many times before with similar scripts and go to edit the menu path. I make the change, save it, and refreshed the scripts and I get the error "eval: unbound variable:" I tried changing it back and I got it again.
Here is the code, again the only line I've changed is

I've been trying to make gimp-curves-spline get variable (which is number)instead of number and I get error.
For example -when I do: *(gimp-curves-spline drawable 0 6 #(0 0 0 15 255 255))*
everything works well as it should be.
but if I do:*(define spoint 15)* *(gimp-curves-spline drawable 0 6 #(0 0 0 spoint 255 255))*
I get an error: *Error: Item 4 in vector is not a number (argument 4 forfunction gimp-curves-spline) #( 0 0 0 spoint 255 255 )*As you can see, all I did was replacing the number 15 with a variable(which is a number) I also check it is a number by the *number?* type predicate
Where is it? On page 332 of Gimp Bible (2010) it illustrates it in the dialog box, but it is not present in mine. I think that I am running the latest version.
I am trying to create a custom message box with variable width and height by passing width height title and list of text. I can get the routine to work if I use preset width and height, but would like to make the box adjustable.
Sometimes I make a fresh transparency blank of gimp. Then I import a jpg. I expect the transparency to appear as I erase. Sometimes it erases and there is white; sometimes I erase and it's transparent. ? Isn't it supposed to be transparent?
This 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?
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.
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.
The edges of this fabric are semi transparent. The grey colour to the area where the arrow points is caused by the photo's original background. Now I'm wondering is it possible to recreate the transparency so that the colours from a new background will show through. I've tried colour to alpha but that makes most of the image transparent.
The rest of the image is mostly black and greys with a splash of red. I would post the entire image but it's copyrighted - DA stock model - so I don't want to break the rules.
How is it possible, to take the brightness of every pixel from the background, and transfer that to the upper layers transparency. (The upper layer is for example all blue). As I said before, I know that this works. I tried everything out and asked Google a lot of times, but I just can´t figure it out.
What I can remember doing there was just take the blue layer and transfer it to another picture. I was wondering because i didn´t do anything special.
Until recently Gimp has either supported transparency of .png image files or automatically added an alpha channel to the image. This I don't know. I do a lot of rendering and have always been able to take a .png or convert any image type to a .png, create a path, and delete everything outside of the path and end up with a transparent background.
But something has changed where I must now manually add an alpha channel to a .png image in order to end up with a “transparent background”. what changed in Gimp that I can no longer just erase or delete a selected area of a png resulting in a transparent area?
In each program I have used from Corel Photo-Paint 11, Paint Shop Pro 5 and 7, to Gimp 2.6.11 the end result is exactly the same.
I select the background Invert the selection to pull it out of the original Paste the remaining image with transparent background or make an alpha channel The background needing to be transparent stays transparent.
The moment I save the image as a PNG, close the image, reopen it, check if the Mask/ Alpha channel data remains in tact, and it does, the transparency is completely removed and the background turns to white. This happens on every one of the programs and I am just at my wits end.
There must be something, an order of operations, a color scheme, a presetup step that -everyone- knows but me, that is preventing this from having a transparent background.
I've to select an area ant turn the background transparent. Previously this was simple: select foreground, invert so background selected, toggle the transparency to 0% and hey presto, transparent background. Now when I do that it goes white.
I have tried using transparency - add alpha channel, and nothing happens: the menu stays there. Is that a glitch in y version of Gimp? and how can I now isolate the background and turn int transparent?
I'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?
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?
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)
I added an alpha channel to make it a transparency.
I used the select by color tool.
I clicked white & removed.
I saved. I switched to eraser - but it is acting like I'm trying to erase something off the transparency layer and won't erase anything. I have the correct layer selected in the layers window.
I want to change the background color to a transparent one. I've tried using Color to Alpha but that makes the sprites themselves partially transparent which is not what I want. My second attempt was to use the fuzzy select tool to select all of the white bits and remove them. This doesn't really work either because on a non white background each of the sprites has a few whitish pixels around it's edge. So what I really want is a combination of the two, i.e. all of the white pixels are made completely transparent, and the whitish pixels on the edge of each sprite are made partially transparent, but the sprites themselves remain opaque.
*) Open the image "Ok.png" - you'll see there's a small green triangle on the right. *) Mark and delete a bit of the triangle. *) Save the image (I checked the 3rd (gamma), the 5th (resolution) and the 6th (time) checkbox).
When I now open the saved image in a different viewer (I use the picasa viewer because this viewer shows the transparent areas nicely), the image is still transparent.
*) Delete the rest of the small green triangle on the right. *) Save the image.
When you now open it in a different viewer, then suddenly the background isn't transparent anymore. (It's then like the 2nd attached pic - Fail.png)
Take any image. Enlarge the canvas to create an area of transparency. Find out you can't draw on it. Click and unclick the buttons by "Lock:" in the layers bar. Get really really frustrated.
What do I do to fix this (before I give up and uninstall Gimp)?
(to pre-empt the innevitable question - I can't draw on an area of transparency. Even if I copy a section of picture and paste into a new layer and move that to cover the transparent area, it isn't visible. Its like there's an area of completely opaque transparency covering everything else.)
