I scanned some images to Tiff format and when I bring them into Gimp I can't seem to get the threshold effect to work. The other color effects work but not threshhold. I check with other Tiff images I have and they work but not for this new set (done on a different scanner).
View 1 RepliesThis was exported to tif and sent to the printer, the glow is a white outer glow.
As I usually do I exported the whole thing to a TIF and low and behold black lines in the print.
This was the bullet proof way of getting what you saw on the screen to hadcopy but sadly no more.
Can this be addressed in SP1, as it puts a serious hole in all the signies bag of tricks for that matter any body who wants to output special EFX from Corel.
I like to repair books with missing pages. Often I can get digital images in tiff or PDF format, but they are often 'dirty', like the one attached. This one seems a good example of the sort of thing I would need to work on.
I need to reconstruct the image, which I think would mean:
i) getting an image that is complete and rectangular with a bleed out of in the same colour.
ii) remove blemishes like library marks, names etc.
iii) reconstruct the decayed text as sensitively as possible.
I want to use the Threshold Alpha command on a Layer of Solid Noise, but nothing happens. If I set the threshold to 255 everything goes transparent, anything below that the clouds are supremely unimpressed. It's an RGB image, has an alpha channel, no Alpha channel lock, the Threshold tool works fine. I also tried creating another test picture with several gradient in greys and colors, and they are equally unaffected by Threshold Alpha.
I'm using GIMP 2.6.11 on WinXP SP3.
i tried restarting gimp but it did not fix my problem. All of a sudden, out of nowhere, my fuzzy select tool selects WAY too much even at a threshold of 1. at 2 it just selects the whole picture.Re-installing did not fix.
i am creating black/white based icons. So it is a 48x48 image. i am mainly trying to fuzzy select black, white, and transparent selections. As you can guess, it has become impossible now and i don't know what i did.
EDIT: Okay so it actually isn't selecting "too much" per-say. i willt ry and explain the best i can here:
Black and white image with the exception of some shades inbetween.Select fuzzy select and put threshhold at 1. Click. Selects all the white (i actually think it misses some). i hit SHIFT and click on a pixel that is slightly not white. VERY SLIGHTLY. In fact, it may actually be white. It fuzzy selects EVERYTHING.
Another example on an image that is Black and Transparent (with shades inbetween) Slect black on threshold 1. It selects All the black AND all the shades inbetween. Eveything except flat out transparent. i hit CTRL and select a shad einbetween and it deselects everything.
EDIT 2: Doesnt matter the threshold apparently. It will do this on any.
EDIT 3: The solution, after all, was so save these problematic images as JPG and then open them as the JPG.
I would like to obtain a black and white image of a photograph of a book page.
My attempt to do this is by running the threshold function over theentire image. This appears to give the desired result, but onlylocally. It appears that the optimum parameters of the thresholdfunction vary by position (i.e., according to some scalar field), withone extreme in the center of the glare and then radiating outward. Sojust running the threshold function over the entire image withconstant parameters always gives sub-optimum contrast for 75% of theimage. Will I have to find a way to run the threshold function withnon-constant parameters, or is there some other tool to do the job?
I have encountered with a Photoshop TIFF image.
This image is a CMYK 8-bit TIFF - no layers - everything very basic (so it seems). I place this image as a link into Adobe Illustrator, then save this resulting file as a PDF.
I open the PDF with Adobe Acrobat, then I use Enfocus Pitstop to check the properties of the image. The Pitstop Inspector tells me that the image is indeed CMYK, but it contains only 1 channel and the image is "Indexed".
When I try to output this file to a printer, I only get the Cyan channel. It seems that the Magenta, Yellow and Black channels are "hidden" or something similar.
Throughout this entire process, the image appears on screen (in all applications) as a full colour image, ie, I get to see all of the channels - not just the Cyan channel.
I have found that if I save the original image as a Photoshop PDF or EPS, everything is fine.
I have also just completed another test and found that if I change anything about the image size (eg change from 300 dpi to 299 dpi) everything is also fine.
I am not able to attach the image, as it is too big for the 200KB restriction of this site, and I cannot compress it that far.
Has any body heard of this type of thing before?

What is the best format to save high resolution black and white photographic work? Tiff? JPEG? Also, I'm confused about the Tiff save dialog.
When saving as Tiff, there is a box I can check labeled "ICC Profile: Grey Gamma 2.2". What does this do?
Also, later I'm asked if I want LZW compression. I want as high resolution as possible, file size is not an issue. So I assume I'm not interested in compression.
But is Tiff the best format for me?

How to save as coreldraw file in .tiff format
View 6 Replies View RelatedI can't see a way to search for this issue that seems faster then looking manually. X4 will open X3 jpg's, but not X3 TIF's. X4 will open the older PSP files, but X3 TIF's show up as black rectangles in X4 workspace and won't open. I've uninstalled X3 already, but do not consider re-installing it as a solution. Previous versions of PSP have been backward compatible for me. If I open a RAW file, edit it and save as a TIF, it will open.
View 3 Replies View RelatedI'm taking the time to edit some of my nicer/older outdoor photos that were taken in jpeg format in Photoshop CS3 and then on to printing with an Epson 3800. I've been told that files I want to print I should make sure that I'm set to an RGB color space (1998), get icc profiles for paper, have photoshop manage colors, etc.
This is all going great! However, I've recently read online that to truly show the full potential of one's photos, those jpeg's should be converted to a TIFF file format...especially when printing (I'm now taking everything in RAW format, but I still have to take care of some of these nicer jpeg's).
Have done several prints comparing same photo in jpeg & tiff and tiff definately is higher quality. Now..my questions concern some of the settings in CS3 when I chose 'Save As' - 'Format' = tiff. Code:
I'm trying to find a editor that will allow me to do some basic things with a very large tiff file created from a wide-format scanner. I had hopes that Paint .NET would do it since it seems to support 64 bit. The file I'm trying to edit is 1.7GB uncompressed tiff. Unfortunately, Paint seems to take forever to load (5-10 minutes), even when I have at least that much available memory on my 4GB Win7-64 machine. Are there any tips to conserve memory or to make this possible?

View 7 Replies View RelatedI am cleaning up the Hard Drive on my Mac G4. My scanned images are taking a great portion of the 80 Gig drive. I finished clearing my external drive by removing nearly 60 gigs of images by storing them on DVD. I will do the same for the Mac drive.
My trouble is that all my images are stored in TIFF format which takes up enormous space no matter the storage. Since I output images in various sizes, mainly prints, to 30 x 40 inches, I need a master image archived in the best format for such. However, I do not want to fill my drives, or DVD, with large files. Code:
When I generate a 32 bit tiff (HDR) in PS CS5 from bracketed pictures within lightroom 4.1, import the tiff back into lightroom, adjust it in lightroom, and then send it back to PS (option "Edit a Copy with Lightroom Adjustments" selected) for further editing, the file won't open in PS. Opening the file directly in PS works, but without the adjustments made in lightroom.
I have tried the same with a 32 bit tiff from Photomatix. Same behaviour.

View 7 Replies View RelatedI'm sending tiff files to GIMP (version 2.6.7 for Windows) from a raw converter. The tiff files contain a lot of EXIF data such as Fnumber, FocalLength, ExposureTime, ISO. and so-on. When I save as jpeg from GIMP, most of the EXIF data is discarded. In the "Save as JPEG" dialog, the checkbox "Save EXIF data" (under Advaned Options" is unchecked. It is grayed out so I cannot check it.
In Chapter 6 of the GIMP manual, it says
Although GIMP uses the “libexif” library to read and write EXIF data, the library is not automatically packaged with GIMP. If GIMP was built with libexif support, then EXIF data is preserved
Here are my questions: (1) Is the Windows version of GIMP packaged with libexif? (2) If not, is there a workaround?
I have over 200 pdf files that I need to batch convert to tiff format. From what I've gathered, this can be done simply using Ghostscript.
