I need to analyze an image and read the value of each pixel, exclude the highest and lowest values (perhaps anything less than 10,10,10 and greater than 245,245,245) , then average the remaining. I may need to do this on each channel of RGB.
I can almost get a result blurring the sample and then using a large brush with the info tool, but is there any other method more direct and all inclusive?
Any quick way of calculating average Parcel Area? I used to export to LandXML and do an area report in CSV. That doesn't seem to be working for me when I export out of C3D 2012.
The workaround I found was to select all the parcels in Prospector, copy to clip board, paste in excel, find and replace "_Sq. Ft._" with 0, then do the average.
Is there a way to select a portion of an image and display the average RGB or Lab values of that area? Right now I can only see the values of selected individual pixels. Instead of manually adding up these values to get the average value which is quite tedious, can someone help me to a better option?

View 9 Replies View RelatedLet's say a have an image mask (see image shown below) where the white areas are the selection islands and then apply that to an image. What I want to do is get the average color for each selection island in that object. Just blurring gives you a gradient effect and if you blur too big, you just get a single color. That's not what I want.

Is there a way to change an object's fill from a gradient to a solid color that is the average of that gradient? What I want to do is have a grid of squares, select them all and apply a colorful gradient to them as a whole, and then average each square's color so I end up with a pixelated look. Kind of like the mosaic filter in Photoshop, but in vector.

View 2 Replies View RelatedHow can I convert all of the transparent (100% transparent) pixels in an image to a specific color?
Adding a color layer below is not the solution I'm looking for, because some pixels are partially transparent and I don't want to modify those ones.
I use the "select color range" feature alot to do things with specific color pixels, but that feature doesn't seem to work in this case.
I am creating bitmap images for a program, where the transparent parts of the image need to be represented by a specific color.
When I open this image in Photoshop the alpha channel / transparency hides the colour pixels underneath.

In Photoline I can create a simple layer mask based on alpha (without creating a selection first), and then turn the layer mask off to reveal the "hidden" image. Or I paint with the brush and only affect the alpha.
In Photoshop I cannot seem to access that information. Nor can I paint or erase the transparency only. To me it seems as if Photoshop treats this transparency as something other than an alpha channel. The channel palette only shows the transparency.
how to convert that transparency to a layer mask, and retain the coloured pixel information? How do I access/reveal the "hidden" image?
I have an image that has corners with partially transparent pixels. I would like to make a mouse-over image of this with the same same dimensions, only a different color.
How can I color this image a different color and still have the partially transparent pixels around the edge. Obviously, I would like the semi-transparent pixels to be semi-transparent of the new color.

View 1 Replies View RelatedI have an image with an transparent background. I want to change all pixels that are not the background to one color. How do I do this? I can't select the pixels, they as arbitrariliy distibuted. I've played with threshold, but that's not working either. I tried Image-->Mode -> Indexed and then Use black and white palette, but that doesn't work either. I thought i would convert all non-transparent values to black, but instead its picking some threshold and making some black and others transparent. Example file attached.

When I went to turn that white background into a transparent alpha channel, it seemed to work okay....except for the fact that when I then went to select the new alpha channel via the Fuzzy Select Tool, it wasn't selecting all these newly transparent pixels.
View 6 Replies View RelatedHow can I control the color of transparent pixels?
I save my image in RGBA (Windows bitmap). The RGB value of the completely transparent areas always turn completely black, and I want to control the color myself.
It may seem pointless, as the color is transparent, but I am using the image elsewhere (for creating mipmaps) where there is interpolation between pixels. Interpolating between 0 and 1 in opacity gives 50%, but the RGB part of the interpolation will mix with black, giving a dark halo.
If I am constantly making frames in photoshop for use in the video world (ie. They will be on TV) the pixels need to be rectangular (or 4x3) in aspect and not square.
I know in programs like After Effects and Combustion you can set when saving an image whether or not it is square or rectangular pixels.
How do I do this in Photoshop if it can be done?
I was using Paint.net but I've found it too limited. The GIMP has much more power and I can do a lot more with it, but I've found a few things I can't figure out how to do.
For example, when I use the Eyedropper tool () to choose a color, GIMP doesn't seem to include any transparency in the selection:
The Colorpicker just chooses the color at 100% opacity. Is there any way to change this so that my new foreground color includes the transparency level?
I am comparing multiple scanned images and I need to find out if one image is darker than another. For example, if you print a document on 5 different printers and then scan those documents into photoshop 7, is there a way to quantitatively analyze how dark each document is. Can photoshop 7 tell you the average darkness of a selected area of an image? They will all be scanned on the same scanner so the only variable should be the printers. I need a numerical value for each, not just a visual comparison.
I am using Windows XP and photoshop 7.

View 8 Replies View Relatedstep 1) I remove the background of my image with the color to alpha method, isolating the part of the image i want.
step 2) I then use color select tool to select all the transparent area that was left behind from step 1.
step 3) I create a new layer.
step 4) Then I use the bucket fill tool to fill in the area on the 2nd layer that was selected in step 2.
This is where I run into trouble. On some pixels where the color filling meets dotted line area (made by color select tool) the color comes out translucent. I don't want this to happen. I want it to be solid ff00ff (color hex) without the random reductions in opacity.
I'm working with sprites and the emulator i use has ff00ff as transparent. I'm getting random pink color coming out of the edges of my sprites. These little specks of pink should not be appearing in game because it is supposed to be read as transparent. i suspect that these specks coming out are related to these translucent hiccups made in gimp.

S = Average Slope
I = Contour Invertval

A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
