|
In addition to the above, image export also appears to use extremely large amounts of RAM for large images, due to the use of QImage (and the resultant large in-memory bitmap). |

We use QString in lots of highly inappropriate places. Most notably is using a QString as a memory buffer(!!!) for images. This needs to be fixed, as it's potentially very inefficient, is a real misuse of QString, and is a sign we actually need a better container for CMYK images (perhaps by giving ScImage the ability to store CMYK image data?). |
|
|
We build a PDF document as an in-memory string before streaming it out to disk (CORRECTION: No, we don't, in fact most parts are streamed to disk very promptly.) Some objects are built as in-memory strings, and then written out. These objects are often mutltiply reprocessed, and are frequently represented as QStrings well before the final write to PDF. QString probably isn't the best data type anyway, since we actually usually want a byte string. We're abusing QString by shoving characters in it that have the same ordinal values as the bytes we want to store, then writing the document out with QString::latin1() to preserve byte values. |
