If your PNG image is 32 bit you will see: Channel depth: red: 8-bit green: 8-bit blue: 8-bit alpha: 8-bit. However this answer is not complete because 8-bit color also shows 8 bits for Red, Green and Blue, only a color palette is used to limit the number of selections (like in good old Windows 2.0). RGB images with 8‑bits per channel (Bits/Channel or bpc) are sometimes called 24‑bit images (8 bits x 3 channels = 24 bits of data for each pixel). In addition to 8 Bits/Channel images, Photoshop can also work with images that contain 16 or 32 Bits/Channel.. Images with 32 Bits/Channel are also known as high dynamic range (HDR) images. Compression Level – Specifies the image compression level for the .png file type.

Assuming you want 32 bits per pixel: Most full-color BMP images have 24 bits per pixel, not 32. A 32-bit BMP could mean (1) there are 8 unused bits per pixel, or (2) there is an 8-bit alpha channel, or (3) all 32 bits are used by the color channels, for example R11/G11/B10 format. Hi everyone, I have a PNG file which is 16bt per channel (total 48bit), but when I check the bit-depth with openCV using depth() it keeps returning CV_8U (zero). int imgDepth = cvImage.depth(); Can someone please provide me with a solution to this problem, or at least … 8 bits can store 256 values in each channel, giving us thousands of colors. 16 bits allow 65,536 values per channel, giving us trillions of colors . Why are not all files in highest bit depth?

We use this when we need transparency in our images. PNG8 often … 2017-12-15 In IrfanView, if you choose PNG as the format for Save As, you get a dialogue box which allows you to suppress the alpha channel as well as to control other aspects of the image output format.

Vanligtvis stöter vi på det i engelskan som “Color Depth”, ”Bit Depth” eller ”pixel depth”. LDR: 8 Bits/Channel eller 24 Bits per pixel som presterar mer än 8 bitar per kanal, exempelvis 16 bitar per kanal (32-bitarsgrafik). Work in any colour space. RGB, CMYK, LAB, Greyscale. End-to-end CMYK workflow with ICC colour management, and 32-bit per channel editing. The typical data rate of an I-frame is 1 bit per pixel while that of a P-frame is 0.1 Multiply blend mode multiplies the RGB channel numbers for each pixel from The pixel array is a block of 32-bit DWORDs, that describes the image pixel by pixel.
Both were RGB with alpha channel. Question: For Google Play Store, does it matter if the bit precision is 8 or 16 bits? PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. For android, you have to supply a 32bit PNG. See this link: Status Bar Icons | Android Developers. I have created my icon with two layers, a white layer and underneath a transparent layer. I understand that a 32 bit PNG means 8 bits each for R, G, B and Alpha.
By far the most common format is to store 8 bits (one byte) for each channel, which is 32 bits for each pixel.

Question: For Google Play Store, does it matter if the bit precision is 8 or 16 bits? Finally, we have truecolor images with an alpha channel, also known as the RGBA image type. As with RGB and gray+alpha, PNG supports 8 and 16 bits per sample for RGBA or 32 and 64 bits per pixel, respectively. Pixels are always stored in RGBA order, and the alpha channel is not premultiplied. I understand that a 32 bit PNG means 8 bits each for R, G, B and Alpha. I added an alpha channel under "channels" tab thing. But I dont think this helps, as the transparent layer I have is nothing to do with alpha.
