You can reduce the drawing size with the reduce option to fit in the doc-. Pixel dimensions: The width and height of the image.ChemDraw strives to be a vital and preferred tool for illustrating chemical. I wish I had pictures of the process because it would be much easier to show you than explain.
Resolution = physical size / pixel dimensions Physical size = resolution x pixel dimensions Image resolution when printed: This value appears in pixels per inch or pixels per centimeter.Photoshop calculates the physical size, resolution, and pixel dimensions of an image as follows: Document size: Physical size of the image when printed, including a width and height.
When you resample, the image quality can degrade to some extent. Or, you can maintain the same amount of data in the image ( resizing without resampling). You can increase or decrease the amount of data in the image ( resampling).
This procedure is more complex than guessing which pixels to remove when you downsample. That's because upsampling requires that Photoshop guess which pixels to add. Removal of data from an image is typically preferable to the addition of data. Whenever data is removed from or added to the image, the image quality degrades to some extent. When you decrease the number of pixels ( downsampling), the application removes data.
Changing the pixel dimensions affects the physical size but not the resolution. The pixel dimensions are always affected. If you change one value, you affect the others. However, if you resample your images, do so only once.When you turn on Resample, you can change any of the values in the Image Size dialog: pixel dimensions, physical size, or resolution. You could get the results you need by resizing your image without resampling.
Resizing without resampling changes the image's physical size without changing the pixel dimensions in the image. Degraded images can look blurry, jagged, or blocky.When you resize an image and do not resample it, you change the image's size without changing the amount of data in that image. For example, if the file size changes from 250 KB to 500 KB, you add twice as much data to the image, which can degrade it. Then, you can use the file size information to understand how much data is removed or added to your image when you resample it. Note the file size value before you change the other values in the dialog box. Changing the physical size affects the pixel dimensions but not the resolution.You cannot set the file size it changes when you change the total amount of data in the image (the pixel dimensions).
For example, if you set the physical size, Photoshop changes the resolution.When the pixel dimensions are constant and you decrease the physical size of an image, the resolution increases correspondingly. To keep the total amount of pixels in the image the same, Photoshop compensates for the value you set by increasing or decreasing the other value. When you resize without resampling, you can set either the physical size or the resolution of the image. The only two values you can change are the physical size (Width and Height in Document Size) or the resolution (pixels/inch). When you deselect, or turn off, Resample, the pixel dimension fields are not available.
Resizing the image this way keeps the total number of pixels constant (200 ppi x 2 x 2 inches = 400 x 400 pixels). Photoshop increases the resolution to 200 ppi. To reduce the image's physical size by half without resampling, you set the physical size to 2 x 2 inches. If you double the size of an image, the resolution decreases by half, because the pixels are twice as far apart to fit the physical size.For example, a 400 x 400-pixel image, has a physical size of 4 x 4 inches and has a resolution of 100 pixels per inch (ppi). Twice as many pixels can fit into the same space.
For example, a 600-dpi printer only requires a 150- to 300-ppi image for best quality printing.For more information about the options in the Image Size dialog, see About pixel dimensions and printed image resolution in Photoshop Help.Selecting a region changes the language and/or content on Adobe.com. Generally, there are 2.5 to 3 dots of ink per pixel. Dots per inch (dpi) relates only to printers, and varies from printer to printer. If you change the image resolution, the physical size changes as well.Important: The pixel dimensions control the amount of data, and the resolution and the physical size are used only for printing.Note: Pixels per inch (ppi) is the number of pixels in each inch of the image. Adding more inches to the image size means that there can only be half as many pixels per inch.
