![]() ![]() Settings.SetDefine(MagickFormat. MagickNET.SetGhostscriptDirectory(_ghostscriptPath) ![]() Results in image with black lines as borders for everything, none of the text is filled with black however the image is now 1bit as expected. Anything equal to or below that value becomes black, while anything larger becomes white. each pixel with a single bit it is either on (black) or off (white). This is actually a simple mathematical operator that just provides a cut-off value. Having pure text pages is of limited use in many cases similar information can. I would need to have the "sharpness" of the 32 bit image but as 1 bit.Ĭould someone point me in the right direction here, feels like i am lacking the knowhow of image conversion. The simplest method of converting an image into black and white bitmap (to color) image is to use -threshold. It feels like the image is somehow being resized during the writing process. This gives me 2 primary issues, when BitDepth is set to 1 why is the PNG image still 4bit? Second the quality of that 4bit image is horrible and unreadable by a barcode scanner. When this code is run with the following setup (Removed BitDepth(1) + 300 DPI) the PNG image is 1169x2303 and (32Bit depth). When this code is run with the following setup (BitDepth(1) + 300 DPI) the PNG image is 1169x2303 and (4Bit depth). Horizontal.BitDepth(1) // Testing (Sometimes commented out) horizontal.Density = new Density(_dpi) // Not working Using (var horizontal = images.AppendHorizontally()) Using (var images = new MagickImageCollection()) ![]() settings.SetDefine(MagickFormat.Png, "Bit-depth", "1") // Not working settings.ColorType = ColorType.Bilevel // Not working My Code MagickNET.SetGhostscriptDirectory(_ghostscriptPath) I have got this working but with some issues that i can not find any solution for. The -fuzz option allows the specified percentage deviation from the pure white colour to be converted to transparent as well. Then use this command: convert image1.png -fuzz 20 -transparent white result.png. png format, because JPEG does not support transparency. The PDF images need to be 300 DPI and have a bit depth of 1 (pure black and white without grayscale). First, you need to convert the image format from. One of our customers need to convert PDF shipping labels to PNG images. ![]()
