Hi,
We are testing png image generation techniques and have found the quality and performance of Molconvert to be excellent.
We have noticed that the actual file size created can be quite high when compared to alternate tools. We can see that the images - even if created in mono with transparent background are getting created with a colour depth of 16 million (24 bit?).
Is there a way to change this color depth as an option supplied to molconvert? I can see the PNG option for b24 and b32 - but that makes the file size even bigger. For a structure like the one attached, an image for web use would be fine at 16 (4 bit?). This could reduce the file size by up to 90% - which is a bonus when loading images of millions of records.
Do you have any suggestions as to reduce the colour depth? Is it a PNG limitation? Should we try to export to a different format first and then convert to a PNG?
Many thanks.
