Using that program I get the actual code for each image that I create, thus allowing me to choose to insert code or use an actual image. I was wondering what would consume less memory, the image code or an actual PNG? I know an image memory consumption is width x height x 4 = bytes in memory but I have no idea whether an image that is generated by code is more memory efficient, less memory efficient or breaks even? This decision is particularly important given the different

One point of the arrow is fixed in middle and at bottom of the screen and head of arrow should move. Length of arrow is fix (it is image). Also I have two buttons and I want arrow to turn left when button left is touched and turn right when right button is touched. What is the logic of this process? 回答1: This is actually pretty simple if you are using a canvas to do your drawing(as you should in your case). Given that you know the

matlab: using the GPU for saving an image off a figure

由 匿名 (未验证) 提交于 2019-12-03 02:35:01
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I use matlab to render a complex mesh (using trimesh, material, camlight, view...) and need not display it to the user, just to get the rendered image. This is discussed in another question . Using any of the suggested solutions (save-as image, saving into a video object, and using undocumented hardcopy ) is very slow (~1sec), especially compared to rendering the plot itself, including painting on the screen takes less than 0.5sec. I believe it is caused by hardcopy method not to utilize the GPU, while rendering the original plot for display
