2016年6月15日 · So how do I get PNG to work. I downloaded the latest version of the emWin with PNG support in the graphics library. I copied the contents of emwin_png.zip to emWin directory where the emWin_Config, header and library are. I still get undefined reference to `GUI_PNG_Draw'

2016年6月15日 · I have this one image attached with this post, which is around 6.5kb, size 320x240 pixel and .png format. To display this image on LCD i have used Segger emWin Bitmap converter and converted it to 24bpp C file, the resulting array is of 225kb. For a 6.5kb png image converter gives 225kb array? which i really don't understand.

2016年6月15日 · Storing the PNG file still compressed in RAM will save quite some RAM compared to storing the image as a bitmap. If decompressing the image from RAM also takes too long, you probably could create a memory device in emWin to hold the decompressed image, which then could be copied to the LCD.

I think you may check if there is cups's library(for ARM) or source code of the filter for png. Then modify the .bb file in yocto to build/install the library to your image. Or using the ARM toolchain compiler to compile the source code and then put the built library file to your board root filesystem.
