View 1 RepliesI have 60-something 24 bit PNG images that I've edited in Gimp, many of them include transparency. I want to batch convert them to 256 colors while keeping the transparency. Can this be done? I did try it in another editor and any attempt to keep the alpha channel transparency resulted in totally washed out colors and transparency where none should exist. Conversely, if I skipped the transparency the color depth reduction went well.

I tried playing with the 'Output Levels' on those areas, but the result is quite uneven. If only the folds were parallel I could stretch the top part over the terrace.

I don't know why the room tool doesn't recognise a simple room delimited by walls whose property divides rooms is set to yes. If I place a rectangle of rooms delimiters the room tool works properly instead. If I start a new project the tool works properly.

It has worked just fine on our 2013 Acad Architecture, but when I sent them (saved down to 2010) back to our client, using 2012 Acad Architecture, the tags disappear and the table is unpopulated.It seems like it must have something to do with the file originally being created way back when, along with some quirk between 2012 and 2013.

I have 400KB png, when I save the same image at home in GIMP as jpg it becomes smaller, but if I save it as png it becomes about 2MB - this is huge compared to photoshop
If I use the save for web plugin, the results are the same for jpgs, but if I save as 24bit png the image suddenly becomes 2.5MB. Why are PNGs in GIMP so large?
PS: I use windows vista, in case this matters.
I've been playing with gimp a lot to edit my photos and how to reduce bright patches in photos that have bright spot that kinda take over the photo. I am using Gimp and cannot retake the photo.
Here is what I did.
1. I outlined my body and took away 100% of the blue, this makes the black look cleaner in my opinion.
2. I then inverted the outline and reduced the blue for the rest of the photo by 50% giving the white a cleaner look.
3. Then I outlined the bright area of snow below my feet and lowered the brightness.
4. I highlighted the sky from the mountain base up and increased the blue by 100% twice.
Here are the before and after pictures.

I want to design a t-shirt and my aim is to reduce a photograph to a two-colour image, more like a symbol, with bold lines and few details. A little bit like this one, taking this one into GIMP. I have been using the software quite a while for private photos, but I have never attempted something like this...
So far I have managed to remove all content except for "the edges" of the car, but I am a bit lost how I can make those edges smooth, because now I can see that the masks I used were not "straight". how to progress making a symbol out of a photo?

So far I have managed to remove all content except for "the edges" of the car, but I am a bit lost on how I can make those edges smooth, because now I can see that the masks I used were not "straight"; the photo is reduced to monochrome. Well, what I am asking is: How to progress making a symbol out of a photo, from scratch?
I found a way to save a sub 1mb XCF file with a select saved as a channel and a layer of the image as a threshold. I can open the original jpg in gimp, select all, copy into new transparent layer in the tiny XCF file, do channel to selection, delete the threshold layer and I'm good to go. I went from a 27 mb xcf to a 0.5 mb xcf with the channel and layer for a 2 mb jpg.
At my low skill level the selects are usually the only XCF elements worth keeping. Everytime I've returned to a saved XCF weeks later because I knew more, I tossed it out and started over from the original jpg unless a select was involved. I could buy a larger HD, but I'm literally living out of 2 suitcases and expect to continue so indefinably. Keeping my pile of stuff small is a prime priority. Store them online? The only internet ISPs available here are rather slow.
how do I reduce the size of an image and place it adjacent to another image. Let me explain it a bit better. I live on the Corner of two streets . A lamp post with the name of one of the streets is on the corner. I want to reduce the size of and place the image of the other street on the same lamp post.

It's washed out the pink frosting into an almost white color and the strawberries are not saturated in color. Is there something I can do to get rid of the white spot and make the image look as if it was shot professionally in a white box?
(in the image, it's the front most chocolate cupcake)
GIMP is in single window mode. The bottom of the window extends down below my screen window, below my taskbar, so I can't grab it with my mouse to pull it up and make the window smaller vertically. I have pulled the top blue bar up as far as it will go, but not far enough - How do I shrink the GIMP window vertically?

View 1 Replies View RelatedI'm using gimp 2.6 on ubuntu. i have some pictures i would like to enhance.
There's that image image 1
and i would like to make it look like image 2
As you can see the second image uses only about 7 or 8 different colors and the outer lines are nice and smooth not stuttering.
Is there a way how i can change the first image to something like the second one, maybe something like replace 10 different colors which are similar to each other with only 1?
I tried and played with the options (bucketfill, posterise, or the cartoon option from artistic menu, increase contrast, brightness etc...
Is there an option to smoth the outer lines etc? i just want the dog, the rest of the background is not so important.
Using a Mac I have created a path round an object and wish to reduce the opacity of the background but do not know how to do it?

View 4 Replies View RelatedThe 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.
My Gimp version……2.6.8.
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?
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 loaded one PNG pic.
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'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 PNG of sprites similar to this:
[URL].........
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)
