Our platform was designed to address the specific challenges associated with international contractor, freelancer and vendor payments. Setup and user onboarding can be completed in less than an hour (compared to weeks or months). Quantifiable ROI is achieved immediately from reduced transition costs and automation time saving (compared to months or years). Automation significantly reduces the risk of errors and fraud. The software can automatically validate invoices and compare them to contracts and work hours reports, ensuring that the amount charged is accurate. Additionally, the software can enforce approval workflows and segregate duties, reducing the risk of fraudulent activities.

Great program with lots of useful tools.

Checked to see how this library would quantize a RGBA true color image. This is for rendering scientific data that has up to 512 levels (or ~9 bit pallette, single hue from black to white), which is of course very limited, but where 1/3 to 1/5 of the data has variable alpha. It is a little slow taking ~8-10 sec to convert a 1024x1024 image (that I'm sure is fine for most purposes), but it does an amazing job building a PNG8 that is indistinguishable from the original image.
