All we know that PNG format offers a variety of transparency
options. However, there is a problem of having an image with partial
transparency. For example, an image with a shadow. To solve this problem you
need to save the required file as a CPT file with the help of Corel PhotoPaint.
After that, open this file in CorelDraw. Open the Export dialog, select the PNG
image format and click Export. Do not forget to make sure that transparent
background is chosen in the Convert to Bitmap dialog and click OK. Finally,
make sure that under Transparency Masked Area is selected and click OK one more
As a result of the actions described above you have
created an image with true transparency.
I hope this information will be useful for the
majority of PNG users.
