The Photoshop is very unstable, it lacks elementary features that one expects in a professional program, and its help file is a bad joke. He/she/it just hasn’t learned PS or know about pressing F1. The two top layers must be transparent, so all the white pixels must be removed. This means that the only way to make relatively nice 3D patent drawings is to combine 3 layers (lines, shading, text) in the Photoshop or a similar program. The drawings must have only two colors (black and white) and they must be either hand-made, or they must look like hand-made drawings. patent office does not accept computer renderings of 3D CAD drawings. I am trying to make a shading for a patent drawing. I don’t understand – what are you going to replace This worked much better although I had to spend a minute aligning the pasted pixels with the rest of the image. I could select all the white pixels, but I could not remove them, so I selected all the black pixels and I pasted them into a new layer.
Then I tried Grayscale mode – it worked much better.
The magic wand always crashed the Photoshop. My first experiments were in the Indexed Color mode. It worked, but it took some experimenting.
If this is what you want to do, Polaroid’s Dust and Scratches could save some work. This avoids degradation of detail in the lighter areas of the image. When using these filters, I find myself using the lasso tool to select dust specks from the shadows, followed by a dose of dust and scratches. Polaroid supplies an excellent plugin and stand alone utility that does this, and it’s free:īoth of these filters use what is called an "Impulse Filter", which removes noise from an image by replacing the noise with averaged values from nearby pixels. Full Photoshop has the dust and scratches filter that will do this quickly and easily. More than likely there are easier and better ways to do what you are trying to do. You may use your favorite method is to get rid of them. Switch from QuickMask back to normal mode, and pure white pixels will be selected. Because of the way Levels is implemented, you will need to do two repetitions of this in order to get absolutely every white pixel. Use levels to set everything below 255 to zero, and everything above it to 255. First copy the image to the clipboard, then go into QuickMask mode, and paste the image to the mask. Here’s one way to select all the white pixels in Photoshop 5 LE. Is there any way to remove all white pixels? The magic wand does not work because it removes contiguous pixels only. I am trying to remove all white pixels from a monochrome (black and black) picture imported into Adobe Photoshop 5.0 LE.
