Description
With the provided PDF a few images seem to be cut off at the top of the pages. On the first page the main image is cut off. As well the vertical font on the right hand side isn't filled in. On the second page, the background image/colour is should go all the way to the top.
I spend quite a bit of time reworking our luminosity algorithm but still haven't had much luck cracking this nut fully. The cropped image is do to a an clipping issue when creating the buffers to apply the forms image mask. The second issue that came out of this was related to how we are apply the 'ca' alpha value to a blendComposite. While testing with this PDF it was found that the we don't apply an alpha to the multiply blending mode but rather add another alphaComposite with the alpha after. The generated the correct effect and make a few other PDF render correctly.
