Photoshop :: Reducing/eliminating Background Noise When Converting To PDF
Feb 17, 2005
I have a schematic that I scanned in and cleaned up PS. When it scanned there was a lot of background noise in a strip up the center of the file.
I've removed most of it and darkened the image itself back up and am pretty happy with the way it prints directly from PS. However, I need to convert it to a pdf (it is part of a manual that needs to be available online). Everytime I do it it comes out horrible with all sorts of fuzz and noise around the entire scanned image. The text comes out okay.
how I can eliminate the noise in the pdf?

I'm attempting clean up some JPG images of product for sale. I do not know the technical terms for what I am attempting to do. I wish to eliminate all of the background space. I wish for the file to display only the product as if floating in empty white space.
I am using Adobe Photoshop Limited Edition; I also may use Adobe Illustrator.

I have a black logo with complex lines, text, etc. The only copies I have of the logo are with a white background (probably from having been saved on a document page?). I want the logo to have a neutral/clear background so that I can paste it on pages with gradient backgrounds, etc. and not have the white show.

My intention was to convert a 3DS-File into an IPN-File, to use it in Inventor.As I did not managed to do this in Inventor, I importet the 3DS-File in CATIA V5 and converted it into a CATIA-CatPart and from there in an IGES.Then I was able to open it in Inventor and made a IPN out of it.
The PROBLEM: The original 3DS-File had 700 kilobyte but the actual IPN 54 MegaByte !

Level: Newbie  OS: Windows 7 64bit   Ps: CS6
Â
I went through a half A***d tutorial (to make an iPad) which was a huge part of my problem ...
Â
The tut would say to do things that couldn't be done - so I would find an other way ... which I believe created problems
Â
when I was done making the iPad and then tried to Group my layers into some sort of order ...
Â
The Noise (Filter) I used on the Main Shape of the iPad spilled out of its Clipping Mask and onto the BG layer ...
Â
or actually onto every aspect of iPad
Â
Am I assuming correctly that having moved the Layers around and placing them into Groups somehow disrupted the Clipping Mask?
Â
I read that I can make a New Group and then just drag the Layers up to the Folder
Â
However, I couldn't find in the manual anything about what to do when moving Layers into New Groups goes wrong ...

I've just upgraded to C&PGD from Xtreme v4. Adding a small amount of noise to background images seems to be becoming more popular these days. I've seem tutorials on YouTube for PS and this technique but couldn't find one for Xara.

I designed artwork for a large banner (84" x 32") so my AI artboard is that large. As you can imagine, with all the text and graphics I used, this file size is 22.8 MB. I need to email this art to the printer, but the file size is too large to email. How do i go about reducing the file size in AI so it still maintains large format print resolution? Will saving to a PDF lose the print quality?

I need to generate some decent grain/noise bakground for web page of size 128x128 or similar size.
I found - Grain Generator at [URL] ...... but it does not allow setup a spicle/grain size only 1pixel. I want dirrerent and random sizes from 1x1px up to 4x4px size.
Can it be simply generated in PSP X2/X4 or some good even online generator?

I want to edit a photo of a car so that the car remains in colour and the background changes to black and white (or should I say mono?). I have seen this several times and wanted to have a go myself. I understand that it can be done in Elements using layers?

I have this image with an intense orange background.
I want to change the color of the background to a light green, or even white (depending on my boss' mood). But the background color leaves me with an undesirable orange color-cast on the old man.
this is only a very rough clipping, the final version will be well refined.
way to eliminate this color-cast, most noticable on his hair. How would you go about it?

How to eliminate the white backgrounds on scanned-in sketches/line art.
1. Open the scanned art work in Photoshop. Make sure that the color mode is set to RGB Color.
If the background is a pure white, skip to step 4. If the background is grayish, go on to the next step.
2. Open the Levels window (Ctrl+L). You should now see a jagged pattern in the center with three arrows right below it. Drag the Black arrow to the right until the background is almost white or until the lines are about to go jagged-mode on you. Click OK to apply the changes.
3. Now adjust the Brightness/Contrast (Image->Adjust->Brightness/Contrast) and move the Contrast slider until the background is white.
4. Select All (Ctrl+A) and copy (Ctrl+C). Open the Channels window if it isn't out already (Window->Show Channels). Click on the Create new Channel button and Paste (Ctrl+V) into that channel.
5. While having the Channel selected, Invert (Ctrl+I) the image.
6. Click on the Load Channel as Selection button and a marquee should now surround the white lines.
7. Go back to your Layers window and click on the Create new Layer button. While having the foreground color set as black, fill the selection with the foreground twice (Alt+Backspace)X2. This should now leave you with the outline of the pencil strokes minus the white background.
8. Delete the original image layer and place a layer filled with white below it.

I just upgraded from PSE 7 and I absolutely cannot stand that they made the parts circled in my image un-moveable (as far as I can tell). Any fix for minimizing these? In my opinion the "Open/Quick/Guided/Expert" panel is an utter waste of space.

I have a BMP image that is part of a larger logo that I need to be cut out on my inline cutter. The problem is, when I convert the whole logo to the plotter file, the BMP image does not show up. I have tried using the outline trace to convert the BMP to a form my plotter will recognize, but when I save the file, it saves it with a white background that shows up in my plotter image. This white background messes up the whole logo.
Is there any way to save the file where the image has a transparent background? I have been saving it as a .cmx file and there is no option to save it as a transparent background.

When I went to add text to a video sequence in the Title feature, the words "Double-click Here to Add Text" appeared.
Which I did. The text I wanted appeared in the sequence and showed up OK after saving and replay--but so did that "Double-Click Here to Add Text!"
I couldn't figure out how to delete THAT unwanted message--any hints on how to do that?

I recently stopped using my HP755 plotter and am now plotting "dwg to pdf". The problem is when I go to plot I get a warning message stating that "this plotter configuration cannot be used" and it goes on to list a few reasons why and selects the "none" plotter. Then when at the plot setup page I can continue to plot as I normally would. Why am I getting this warning and how do I stop it?

I have a subdivision plat that I'm working on with a curved lot line. When I label this particular lot line, Civil 3D labels it like it's two different segments. In other words, instead of labeling the line as a 100 foot long arc with a radius of 100 feet, it labels it as a 60 foot arc and a 40 foot arc. I can't figure out how to combine the two segments.Â
All of the lots lines were created from polyline objects, and there was no break in the original line work (nor is there any indication of a break in this location when I select it).Â

The image above is for a website which has a colored background. The image will be exported as a PNG file so that the background is transparent. I am unable to eliminate the space above 40th. It seems the bounding box around the character can not go past the artboard area. Is there a way to crop in Illustrator or do something to the character so that it is flush at the top on the artboard area?

For a website, my avatar must be less than 100px square and less than 30k of page weight. I'm having a terrible time doing this without the photo being a blurry mess once uploaded. The first two photos are relatively heavy because they've been edited, so I thought I'd try a photo that hasn't been messed with. I notice that even that photo, at 72ppi and 100px is still over 100k in weight. It will probably also be a mess

How would I do this without the image distorting radically?

I've been working on some pictures that will be printed on T-shirts. The problem is that I've got alot of different color in the pictures which would result in a very expensive print. What I would want to be able to do is to reduce the colors in the pictures to only 4 specific colors (plus black and white). The colors must be very specific. for an example: "ff2600". To be totally clear: I need the ALL the different types of yellow into be transformed to just one type of yellow. So my question is am I able to do something like this in photoshop?

i'm just learning some basic 2d (i work mainly in 3d) and am in the middle of reducing/cropping some of my images so that they fit neatly on a web page. i have a couple of questions:
1. when i reduce (resample) an image, in the resample dialogue there is no easy way to just reduce by a given multiplier (e.g. 0.5) and at the same time, see what the resulting size will be.
for example - i have an image that is 2592*1944 pixels. i would like to be able to enter a multiplier and see what the resulting resolution would be /before/ i commit to the new size. this is possible in a very old version of corel photopaint that i have and so my first question is can this be done in photoshop or do i have to resize elsewhere?

I have a cybershot and have it set to 1280 x 960...Fine. The pictures look great but sometimes when I upload to walmart or shutterfly them become pixelated. Or when I use irfanview (PC only program) to resize to something smaller and pixelates them as well.
Should I change the camera settings, if so, to what? Should I use PS to resize them?

I want to reduce the colour levels in a picture to four, or limit the amount colours of an image to 4 colours.
I have many black and white images and I want to remove all but 4 scales of colour so that I have
White
Light Grey
Dark Grey
Black
The closest thing I have found is in the filter gallery bu using cut out and reducing the number of levels to 4 the problem is this tends to blurr some of the details as part of the effect whereas I want to maintain the crisp edges of my image so that it just looks flatter
I would also like to know if there is a method to do this and have it somewhat scaleable so I can decide on the range of colours in the current image that would fall into each of the new colour categories so that I can adjust itcase some details are incorporated into say the dark grey layer and they should be black ect?
I'm sure I have seen a very simple feature to reduce the colour range of an image, maybe that was in paint shop pro it was a long time ago.
