View 1 RepliesIt blows my mind that somthing this simple isnt all that simple. I used the eyedropper tool to slect a color from another photo, then used the brush while fully magnified to change the color of each pixel.
It was coming out a weird greyish color, and I noticed that if I clicked more than once, it got darker, but so did the pixels directly around the one i was editing. So, i copied both pictures, loaded them into paint, and went to town.
It worked, but then when i copied it back into photoshop, it had a black background (there was no background in the original pictures) around the sprite I was editing. I tried to use the magic wand tool to get rid of it, but it took parts of the sprite with it, so...
Is there any way that I can edit the color of a single pixel (or hell, even a group of pixels if they share the same exact color would be nice...preferred, even) accurately? If not, what program could I use that would keep the transparent background?
Via VBA macro, some way of getting RGB/CMYK color values of a bitmap pixel by pixel?

View 3 Replies View RelatedI ma on a PC with Windows7 using CS5.5 Extended. I am working on a piece where sometimes I have to deal with just one pixel at a time. If I am making a pixel black I select either a square or round brush, hardness 100, Opacity 100 and Flow 100. I have tried Normal Mode and several other modes but no matter what I always seem to get some bleed(shading) into other pixels and it takes a few clicks to get a solid color.
How do I get the color I want with one click in the pixel without bleed?
I would like to know if there is a way to change the colour of the font of the file name at the top of the autocad window. It is currently white. The problem is our company standard desktop background colouris fixed as shown a light blue, and so I cannot read the file name of the autocad drawing.

View 3 Replies View RelatedI have very complex file, with hundreds of paths, shapes, text, outlined text, etc... It's a brochure with graphs, scematich drawings and text.
Last moment, the client like the reverse the colors from (current) Black on white, to all White on dark gray background.
Problem is, I can't seem to find easy way to just change the colors, without selecting one by one, every single object. When I selest all and choose white, it start filling paths with solid fill... Editing it wastes allot of my time and I have many pages to do.
Is there any way to simple change color of everything at once, just from black to white ? Or do I have to go object by object manually ?
I'm using a Canon 40D, Photoshop 6 and a Mac Mini running OSX 10.8.4.
I'm loading a RAW image from my Camera into Photoshop in 16 bit mode. As I understand it, my Canon 40D has a 12-bit A/D and RAW images have a 12 bit depth out of the camera. Loading them in 8-bit depth would lose some dynamic range/resolution, so I choose to load them in 16 bit mode.
Once the RAW image is in Photoshop in 16 bits, I scroll over parts of the image with the color picker to see the pixel values. This is where I lose understanding of what's going on. The color picker shows pure white values as 32768 and pure black values as zero. Apparently Photoshop (or Camera Raw) is shifting the 12-bit camera data up to fill the top 16 bits in Photoshop. But this is not entirely true! If it truly shifted all 12 camera bits into the 12 MSBs of the 16 bit Photoshop value, wouldn't the max white value be 65535?? If the 12 bits were shifted into the 15th bit, wouldn't the max value be 32767?? Where does 32768 come from? Also, what is Photoshop putting into the LSBs after it does the shifting?
I'm trying to do some averaging of lots of low light exposures using Linear Dodge in 16 bit mode. If photoshop indeed shifts the 12-bit camera values to the MSB of the 16 bit word, I'll eventually run into clipping when I sum my images. I'd have to go to 32-bit mode and that really slows down my system, almost to the point of uselessness.
What's going on in 16-bit mode?
At the 3200% zoom level, with small movements of the cursor, I get different color readings within the boundaries of a single pixel.
View 10 Replies View RelatedWe do hundreds of images for our main client for print purposes. As part of the work, they want all of the final images run through Save for Web saved as both a .jpg and .png file at 1000 pixels wide.
The problem is, if you try to create an action for this, the size the action saves is a percentage and not a pixel width. So it's impossible (so it seems) to save an action that sets the scale as a proportional resize with a fixed output of 1000 pixels wide. Since all of the images vary in size and it insists on saving the size as a percentage, you can't create an action that will work.
I've tried to see if there's a way to modify the action to change the output to a pixel width, but can't see how to do it. Is this even possible? It would save us TONS of work not having to manually open each image twice and saving for each format.
I am using Elements 9 and have used Elements since V5. Today I tried to re-size a jpeg and the program would not let me change the pixel size.

I can change colors in other drawing files on this computer. The color of a layer can be changed if I open the drawing file on another computer.
If the drawing is "save as" to a new file name and the new drawing is opened, it still will not change the color of a layer.
If the drawing is "save as" on the computer that will allow the color to be change and opened on this computer it will not allow the color of the layer to be changed.
Is there some Script / Macro to change / convert / apply color modes in all bitmaps of a file? (convert them all to CMYK lets say)
Wx Tools have "set DPI", "downsample", "resize" but not "change color mode".
I quite often import hardware models downloaded form various mfg or supplier websites. McMaster Carr for example provides a great deal of hardware models. While they offer native formats for SW they do not do this for IV (not many places do)
Since the [imported] models often open up with default properties, I change the material to something that closely represents the actual hardware or item. In some cases, there are certain portions of the item that are in reality colored or textured differently and I sometimes want to duplicate that for aesthetics and a more accurate view for people that use my assembly files.
In SW, it was always real easy to select just a face (regardless of whether the surface was part of an entire part, a feature, an imported solid body, etc. I could always change the properties of just a face or slection of faces. Since it was a standard pc of hardware, I had no concern about updates.
I have a part file that contains two imported solid bodies. If I select just a single face and try to change the color of it, it changes the entire part. Not what I want.
I'm using sendcommand to draw various shapes in autocad.
the problem is my application (wpf) uses pixel units while autocad uses inches by default.
how can I change autocad units to pixel programmatically?
I have a 2013 Macbook Pro 15 with discrete graphics and plenty of RAM, so I cannot image the computer is to blame. I have 2.8.10. When using features like auto white balance it takes way too long to change the pixel colors. I have installed GIMP in parallels and it runs faster through the Windows application than it does directly on my Mac. Is this just the result of the mac build being not as refined? Is there a setting that I need to change? I have the Tile Cache on 8GB and number of processors on 8 (4 actual, 4 virtual).

When i save a file "for web" as a jpeg with a specific pixel size (320x50 for example) and then send it by email to someone, when they open it the dimensions somehow change. Even though on my mac when i "get info" from the jpeg the dimensions are correct.
I am preparing images for the web and I really have 2 questions: one about gifs, and one about jpgs.My standard procedure is to reduce the image to the desired pixel dimensions at 600 dpiThat gives me a crisp small image. then I either use it as is if the file size is low enough (I try for under 600 kb) or convert it to a gif with the save for web and devices tool.
So here are my 2 questions (I will count this solved with either answer)
1) When I convert to a gif I have the 4 boxes: one with original size, the other 3 with options but often the options are too low res for me How do I change my 3 options to start at a higher gif res?
2) If I try to reduce the file size of the jpg in the image size box I set the resolution lower ( 400, 300), which lowers the pixel dimensions and the filesize, but I don't want to cahnge the pixel dimensions. And If I reset the pixel dimensions back to the size I want them, even though it is a lower resolution the file size doesn't change.
How to reduce jpg file size using only the resolution, not pixel dimensions? PS I have tried messing with checking and unchecking the 3 little boxes( scale styles, constrain proportions, and resample) but nothing has worked.
I'm trying to create a soccer field. I searched on google images for examples to learn from and I found this one really good one. The grass looks great and is just what I'm trying to do. [URL] .....
I loaded it into to gimp to have a closer look, and all the artist has done really has used lots of different greens, usually a different color on each pixel. How do you think this person went about creating the grass? Do you they colored each pixel individually then saw what they had done and adjusted it until they got it right. Which would probably take a really long time. Or do you think there is a quicker way?
Would it be possible to have an option that allow color picking to pick document's pixel's color, rather than current layer's color with its opacity ?
I really never want to pick a color from a single layer. I always want to pick the color I see, and without its opacity, the one that result from the blend of all layer on the document's pixel on which I pick the color.
I have two art objects on two layers. I want to match to the pixel the two objects that otherwise could be exactly the same but one layered object was imported slightly smaller.
The scale tool has good scale handling, I just want to measure the tool spots to the pixel to gain an exact scale size factor and match sizes.
I know how to crop images but want to be able to view the resulting pixel measurements (ie, 1600 c 1200 pixels).

But I have been searching the default (no plugin) tool box for anything that can do the Magic Wand Tools job. I just have not found it.
Magic Wand - select a pixel/color on the screen. Magic wand will then select all colors that correlate to your selection. I use the magic wand to kill backgrounds out of photos.
"Image > Print Size" really IS the command you are looking for.
The key is to pay attention to the units-of-measure shown on the Print Size dialogue box:- The "Width" and "Height" values under Print Size are displayed in real-world units (inches, mm, etc.), not image pixels.- The "Resolution" values are displayed in pixels-per-unit.- You cannot change your image's pixel dimensions (aka scale the image) from the Print Size dialogue. That's what the "Scale Image" command is for.Remember the relation between pixel and print sizes is:(print size) = (pixel size) / (print resolution)
When you change the image's print resolution, of course the real-world size (the "width" or "height" shown in the Print Size dialog) of your image will update to reflect the new print resolution -- that value is calculated from your image's actual pixel size and whatever resolution value you just entered. This is totally normal behavior -- in fact, it's expected. If you change an image's resolution from, say, 150 pixels/inch to 75 pixels/inch, this doubles the print size of your image but only the print size; the image's pixel size remains precisely the same as before. (You can confirm this by comparing "Image > Canvas Size..." before and after changing the resolution.)
And as others have stated, if you're using the image for Web viewing then its print resolution has absolutely zero effect on how it will appear onscreen (print resolution only affects, well, actual printing), in which case you'll want to use the "Scale Image" command to actually scale your image larger or smaller.
