1.I Open a JPG image with mspaint,and Ctrl+C copy all,pasteSpec to CAD as Device Independent Bitmap(or Bitmap meta File),it show that the image color has converted to 8bit,why this happend with  cad2008/2013/2014?

And then i test it on 2020,it ok,no convert.is there any system variable i have changed?

 

2.my jpg sizes is 84kB,but when i save the dwg in 2020,the dwg File is 6.8M,how to reduce the dwg File sizes?In 2008,the dwg File size is 780kB,but the image get blured.

Hi,

>> it show that the image color has converted to 8bit

Use the IMAGEQUALITY command to control image quality.

IMAGEQUALITY is alway "High", but the image is still blur.When I zoom in ,it seem better,When zoom out,it seen bad.

 

Image1 is paste from word,but dwg File is large,Image2 is screenshot of Image1,and pasteSpe as Device Independent Bitmap.

maybe it's a visual issue depends on your visual display card . if you try from  -GRAPHICSCONFIG command to disable hardware acceleration , any changes ?

Nothing changes.

but if I _insertobj  as Brush ,it work OK, and file sizes can reduce as the pixels reduce.

Maybe this is the answer,but it's Complicated to operate _insertobj,and   Iwant to know why "Device Independent Bitmap" is blur when zoom out.
