    Hello.

    I’m converting HTML source to PDF format. The HTML contains some references to a servlet that creates piechart image. It appears that PD4ML recognizes the call to the servlet in the HTML, and the debug info provides image size information about the piechart image.

    However, PD4ML reports that the image type is unknown and does not render the piechart in the PDF document. What can I do to rectify this? Find the debug information below:

    version: PD4ML 351b1 Pro (eval)

    .text { font-family: Arial, Helvetica, sans-serif; font-size: 8pt; font-style: normal; line-height: normal; font-weight: normal; font-variant: normal; text-transform: none; color: #000000; text-decoration: none}
    .bold { font-family: Arial, Helvetica, sans-serif; font-size: 8pt; font-style: normal; line-height: normal; font-weight: bold; font-variant: normal; text-transform: none; color: #000000; text-decoration: none}
    .title { font-family: Arial, Helvetica, sans-serif; font-size: 9pt; font-style: normal; line-height: normal; font-weight: bold; font-variant: normal; text-transform: none; color: #000000; text-decoration: none}
    .underlined { font-family: Arial, Helvetica, sans-serif; font-size: 8pt; font-style: normal; line-height: normal; font-weight: normal; font-variant: normal; text-transform: none; color: #000000; text-decoration: underline}
    .7pttxt { font-family: Arial, Helvetica, sans-serif; font-size: 7pt; font-style: normal; line-height: normal; font-weight: normal; font-variant: normal; text-transform: none; color: #000000; text-decoration: none}

    But what type of image does piechart actualy return? PD4ML supports by default only Web- and Java-friendly image types: GIF, PNG and JPEG

    Also “image size: 1895” log entry does not 100% mean it got an image. It still may be an error HTML message. The space characters in the image URL are possible reason of the error.

    Your suggestions were extremely helpful.

    As it turns out, the issue was a combination of bad path information and the white space between some of the servlet parameters. Once thoses issues were resolved, PD4ML was able to resolve the chart image (which was PNG). It complained about there being an excess number of colours and then reformatted the image, but it now shows up in the PDF. Here is the new debug info:

    image not yet in cache: https://xxxxxxPieChartServlet?Title=May+30%2C+2003&points=2.5%2CCASH%7E1.6%2CMM+FUND%7E71.7%2CFIXED%7E24.2%2CMUTUAL

    image size: 5795
    can not embed https://xxxxxxPieChartServlet?Title=May+30%2C+2003&points=2.5%2CCASH%7E1.6%2CMM+FUND%7E71.7%2CFIXED%7E24.2%2CMUTUAL. PNG should not have more than 256 colors. Reformatting image…done in 5592ms.
    PDF creation done.

    Thanks a whole bunch for your help!!

    Cheers,

    The marked with red is a warning.

    PDF allows to embed JPEGs and some species of PNG “as is”. Transparent, interlaced, “too-multicolor” PNGs need to be reformatted to the native for PDF not-lossy image format (more-less identical to GIF). As a result PDF size grows. However it is almost not noticeable for small images.
