Is there anyway to view the properties of a DWF file such as the DPI
setting used during creation, etc.?
We have all users mapped to the same set of PC3 files, but when one
user creates a DWF from a sheet set, the result is about 6.7MB in
size. When a different users creates a DWF from the same sheet set,
the DWF is about 24MB in size. Assuming that publishing from a sheet
set uses the "DWF6 ePlot.pc3" driver and it's settings, I don't
understand why this is occurring.
The DPI property is only valid and optional for graphic resources and images in 2D graphic. Also, please note that, the DPI attribute is optional in dwf, i.e., it may not be set.
1. To get DPI from image resources: call scannedResolution() on the resources of DWFImageResource.
A return value of ‘0’ means the DPI was not set.
2. To get DPI from image objects: call the dpi() method which is provided by both WT_Image class and WT_PNG_Group4_Image class.
A return value of ‘-1’ means the DPI was not set.
My suggestion is to ask the developer of pc3 plot diver of the product you are using for the root reason why this problem happens. Indeed the size of dwf files are determined mainly by the publishing process.
Please let me know if you have any further questions.
