![]() ![]() But usually it may be better to just clear last reference to picture early when you don't need the big picture any more.įirst tests on Windows seem to indicate that on Windows for DirectDraw Xojo also uses a similar system as drawing as memory usage goes up when you draw a picture into another one. ![]() Usually you may never need to do this, but if you load a lot of images, keep them in array and draw them into smaller ones, you may need a lot of memory, so clearing the cache may be good, especially for a 32-bit application, where memory is tight. This frees the memory for the cache and does not draw something as the coordinates are negative. Cached images and files should be the fourth options. A window will pop up that indicates the types of data saved by your browser. Scroll down until you reach Clear Browsing Data and select Choose what to clear. go to the folder /Library/Caches/Realbasic (/Application Support/REALbasic 2006/ for REALbasic 2006) by clicking through the folders or using the Go to. You can clear the cache for example with the following call: It should be the second option below the search bar. Move all stuff inside this folder to the trash. But the cache is invalidated and freed, when the graphics of the picture is used. go to the folder /Library/Caches/Realbasic (/Application Support/REALbasic 2006/ for REALbasic 2006) by clicking through the folders or using the 'Go to folder' menu command. And the cache stays there after the drawing for the case of another draw command. The CGImage consumes about the same memory size as the normal picture part. When the picture is drawn or some plugin function requests a CGImage for the picture, Xojo will create one and cache it. to try and connect to MySQL from XOJO and have encountered the following. ![]() If the picture has a mask, there is a second CGBitmapContext for the mask, which doubles the memory usage. XMLStyleSheet.Constructor() PixmapShape.Constructor(image as Picture) ObjCBlock.Constructor(theDelegate As Object) Size.Constructor() OLEObject. 6.4.1.2 Caching SHA2 Pluggable Authentication On the server side an inmemory. So the pixels are hold in a CGBitmapContext for the actual picture. On MacOS the picture class implementation for an editable picture uses both a CGBitmapContext for the pixels and a CGImage for drawing it. Questions about using FTP with Xojo Cloud, ask me here or send me an email. The only other way to do a refresh is to quit your FTP client so that the cache gets deleted. Disconnecting and reconnecting will not do it because you are still looking at the cache. Let's check how the implementations have an effect on memory consumption. You need to double-click into the folder with the changes and then refresh. The Xojo picture class internally has several platform dependent implementations with slightly different behaviors. ![]()
