GIMP :: Automatic Resizing Or Preview File Size For GIF?
Jun 30, 2012
I'll come straight out and admit: yes, my real problem here is my laziness but, ignoring that, the 'problem' I have is getting so tired of and annoyed with the whole trial & error schtick that comes with saving animated gifs (scale image, save, check file size, repeat to first step until file size is finally desirable).
Two possible solutions come to mind, one I admit is probably quite unrealistic but I would think the other has a good chance of existing.
First, the unrealistic solution possibility. Is there a plugin or anything else where I can input a file size and it could calculate the exact (or close to exact) scale I would need to resize to if I want the gif to be around that file size? (i.e. "For this gif to be 879kb your best bet would (probably) be 515 x 283")
Now then, the more realistic (or at least I think it is) solution possibility. What about being able to preview a file size of an animated gif before saving? (i.e. "If you save this 400 x 226 gif it will most likely be '(insert byte size here)'kb")

1) How do i deal with digital photos from a camera? I mean, if i have a
1280x960 300dpi 3.5MB photo , how do i resize this into a smaller photo to be uploaded to a website? Should i change the resolution to 72dpi? which makes it 307x230 with a file size of 207 kb. But how come when i tried to change the pixel dimentions to 307x230 (leaving it at 300dpi) the file size was the same at 207kb? how should i really resize photos? how do i deal with the resolution, pixel dimensions and document size?
2) In saving graphics to be uploaded to a website, whether a resized digital photo or an original artwork, what format do i use? Jpeg? Gif? Png?
I normally use Jpeg but what confuses me is the jpeg options, whats should i use Baseline Standard or Baseline Optimized? Another thing, how high should the quality be, im afraid to set the quality to high because it might take time to view on the webpage but i also dont want to sacrifice the quality.

In playing around with some settings while saving a .png file, I noticed some weird results. For this example, the original image is 300 x 300, but I want the final size to be 200 x 200. I get different results depending on the order I perform the following operations (I never thought the order mattered until now).
1. start with 300 x 300 image, choose save for web, select png-24, with transparency, white matte, convert to sRGB, change image size to 200 x 200, then save - the file size is 37kb.
2. start with 300 x 300 image, use Photoshop's "image size" to change to 200 x 200, then save for web, etc - the file size is 111kb
So depending on which step I resize the image, the file size is significantly different - if I resize BEFORE using save for web, the file size is much larger. This is just weird to me, but I always resize AFTER choosing save for web, so that's why I've never caught this until now. In case you ask, while using Photoshop's "image size", all three options are checked at the bottom of that window, so nothing is getting re-sampled or anything like that.
The only thing I can think of is each of those methods treat pixel data differently when reducing the dimensions. When I overlay both exported .png files on top of each other, I see no difference in pixel quality and/or color shift - so why the big difference in file size? if I just save the file straight to .png, the sharpness is much better, and the file size is 46 kb. I did notice when saving for web, the colors become a little more saturated.I've never really paid much attention to the results when exporting .png's.

way to specify a certain MB to hit when resizing images using an action?
The reason I ask is that I work with TIFF files that generally start at 60-100MB which I then have to resize to be around 25MB - and I'd like to build this into an action that I can repeat on all images.
At the moment, I'm doing a little guess work when creating an action that employs the Fit Image function. If the image height:width is close to that of A4, I find setting the fit image option to around 3300x3300 pixels usually works. However, a lot of images that I process don't fit to such proportions, which is why I'd much rather be able to set 25 MB as the target size instead, if this is possible...

I have about 1000 images that need to all be resized to 5MB. All the images are in different color modes, have different resolutions and pixel sizes. Is there any way to make an action to resize image to 5MB? I don't care about pixel dimentions or resolutions, I just need all the images to be 5MB.
I'm running Photoshop CS 2 on Mac OS X 10.4

In Photoshop CS6, if you save a picture as a 32-bit JPEG, there is a little bit of words saying how preview and file size is only available in 8-bit, and then it spells available a second time incorrectly "available".

When I preview an image in windows, the properties panel says my file is only 958KB with dimensions 2400 x 2369. But when I open the file in photoshop (I have CS6) , it says my file is over 16MB with the same dimensions.

I have recently upgraded to 2.8 and am having problems with export to jpg, as opposed to old system of 'Save As" jpg.
When "Show preview in image window" is ticked, File size always appears as 1.3GB. If 'Quality' is reduced, file size displayed does not change to a new reading as it used to.
When I go ahead and export, the file is much smaller than 1.3GB. What do I need to do to get the file size in 'Export Image as JPEG' window to show an accurate file size?
Using Windows 7.

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.

I am trying to create a PDF/X-1a that is exactly the size (dimensions) of the .xcf file (15x12in.). There are two ways to do this that I have found at this point. Export does save the correct size, but I can't find a way to change to the x-1a format, or print to PDF which does save the correct format but doesn't save the correct size. When printing to PDF I go into Preferences>Adobe PDF Settings and change the Default Settings to PDF/X-1a and change the Adobe PDF Page Size to 15x12 (custom created page size). When it prints the PDF ends up as an 8 1/2 X 11 file.
Two notes:
1. When I go to Page Setup in Gimp I cannot set a custom page size .
2. The only reason I need the X-1a format is because when I export to a standard PDF the ink density for the black goes above the 240% limit that I need for the printers. If I could find a way to get the ink density results I need without saving in the X-1a format it would be just as good.

I have used Gimp a bit, and before that PS quite a bit. I have never had to use the size constraints for sizing a file to fit a large format printer. I will be getting one any day so I would like to be prepared as much as possible. When I was at another shop, the owner used one of the cropping functions to set the finish print size and then she could move the box around to locate the best print area and remainder to be cropped. She was using PS. I would assume I could do it also in Gimp, but have not found a way to do it yet. What am I missing. Even if the printer software will do it on the printer, I would like to be able to show my customer on a PC monitor what they might expect.

I've been using GIMP to make GIFS for a long time now, but recently the "optimize for difference" option I've used is having the reverse effect it should have- ie, it's making the file larger. Here's an example. It's the exact same image, same dimensions, same amount of colors. The first one is unoptimized, each frame is a full picture, and it's file size it ~149kb. The second one is the same as the first, except optimized with about ~50% of the pixels removed from each frame (except the first frame obviously), and yet it's file size is ~155kb. I can not for the life of me figure out why an image with most of it's pixels removed is creating a larger file size. [URL]...

My current photo editing software (Microsoft PhotoDRaw) has the ability to do this and wondering if I can achieve the same in CorelDraw X5 or PhotoPaint Pro X3. I just reinstalled both and need to start using them since PhotoDraw only work up till Windows XP and I use Virtual Machine to run it.
Here you go. If say I open a new project to any page size of my choice and import any image (any size) into the page. Is there a way I can automatically fit the page to the image size in either CorelDraw X5or PhotoPaint X3? That is, if my default page size is letter (8.5"x11") and I import an image that is 2.2"x5", can I automatically fit the default page to the fit the image at 2.2"x5"? Really very handy too. Can I also do the reverse image to paper size? If I can do either, where do I go?

URL...I use the fill tool next to an already established color and it does this blending, I'm assuming it's a simple fix or just user error somewhere, but how to fix?
(In case it's important the Gray color was made using the Free Select Tool and Fill with FG Color command and the White was the Bucket Fill tool)

I have many scanned images of my collection and need to automate the process of rotating the image so that it is "square" and then cropping to remove unwanted background.
I have learned GIMP enough to do this manually with the rotate and crop tools but I have 1000s of images so how to automate this process.

So I recently got my graphics tablet and have been playing around with it on GIMP, getting the eraser and pressure sensored stylus configured. But I'm having a weird issue- the two side buttons on my stylus already have inputs from GIMP (that being pan and image menu), regardless of what I select for it on the control panel's 'Bamboo Preferences'. I'm not sure how to change it after looking around into the programs preferences window, including 'Input Devices'. Uh, I've checked that my drivers are up to date and I have Windows 7 Home Premium x64 on a crappy laptop, if that means anything... This is really irritating me as the input GIMP determines and the ones I choose from the control panel happen simultaneously and I just want my own inputs.

I am using gimp in Lubuntu 12.04 (using gimp 2.8). The Wacom attached is a Splash.
When I select a brush/color besides the default, it automatically switches to the default/black when the pen gets close enough to be detected by the tablet.
