The Details When working with document rendering, particularly in C applications using a specific PDF rendering library, users may encounter unexpected behavior when utilizing various flags, including kPDPageIsPrinting. In this case, the user... Read More
APDFL: Rendering Functions
If the input document was originally rendered with no smoothing or antialiasing of any kind, you are essentially starting with a lot of glyphs that all have extremely rough edges, being rendered with nothing but black or white squares. If this is... Read More
Add the member flattenNoLimit to the PDPageDrawParams structure. This will help if lines are missing from your output file. When this value is set to True, Adobe PDF Library will ignore some limits on the Flattener to ensure the user gets the best... Read More
Adobe PDF Library does not offer a single interface that will allow control of both Optional Content and Annotations at the same time for a PDF document. PDPageDrawContentsToMemory() allows selection of Annotation faces, but does not have control for... Read More

APDFL lets the client define the output color spaces. The APIs in Adobe PDF Library that set the default output color spaces are: PDPrefSetWorkingRGB PDPrefSetWorkingCMYK PDPrefSetWorkingGray These allow the client application to pass in an ICC... Read More
When using a function or object to print PDF files, you might sometimes see the print job fail, where some or all of the fonts are missing. If you embed all of the fonts in a PDF document, it can be sent to any printer, on any system. The speed of... Read More
You can draw objects from a PDF document to a window in a specific order. You could draw out of the text stream first, then a graphic, and then a vector image. For example, you might want to render the text objects in a PDF document, and leave out... Read More
The core Adobe PDF Library can be used to render a PDF page to a bitmap. The user application must then take the bitmap and add the appropriate image header (TIF, JPG, etc.) to the bitmap. If are using the Java and .NET interface, the product... Read More
When rendering with PDPageDrawContentsToMemory, specify 1 Bits per Component (BPC) instead of 8 BPC when using DeviceGray as the csAtom. A component here refers to a color channel; RGB has three (red, green, blue), while CMYK has four. See the... Read More
