问题 I'm interesting in creating a layered tif with Java in a way that Photoshop will recognize the layers. I was able to create a multi-page tif, but Photoshop does not recognize the pages as layers. The pages are viewable with Acrobat though. Anyone know how Photoshop stores tif layer data and how that could be generated with Java? Thanks. 回答1: I have researched this for my TIFF ImageIO plugin, and as far as I understand, the way Photoshop stores layer information in TIFFs is completely

问题 I am attempting to find documentation of the psd file format so I can read in a .psd and then save out the individual layers as files, along with do other modifications.

Now, I need to get the path coordinates of each object, and I don't want to hover over every corner and manually write down each coordinate. Is there an automated way to get this path? Maybe there is some application or web service whence I can send my image and get the path in return? I have tried

问题 I need to create a layered PSD file with ImageMagick or any other command-line tool available on Linux platform. Since I need to do this on Linux server, I can't use Photoshop scripting.

问题 I'm looking for an algorithm to convert an RGB color to CMYK. Photoshop is performing the conversion below: R = 220 G = 233 B = 174 C = 15 M = 0 Y = 40 K = 0 回答1: The conversion from RGB to CMYK is dependent on the physical device/process being used to lay down the CMYK ink. These are represented in software as Color Profiles. ICC and ICM color profiles of physical devices determine the resulting colors. If you are not concerned with true representation on a physical device then use the

问题 I understand that a Surface Blur in Photoshop is a bilateral filter. In the iOS Library GPUImage there is a filter GPUImageBilateralFilter with parameters of texelSpacingMultiplier and distanceNormalizationFactor. Would these match up directly to the Photoshop Surface Blur options of radius and threshold (respectively)? And would the values to these parameters be the same? Thanks! 回答1: Not exactly.
