While in SFML I simply see more of the game’s world the Scaling Modes in SDL3 Published on 22/03/2025 in Rectangles: Texture Positioning and Scaling in SDL3 Full resolution (600 × 294) ← Previous Next → In thise chapter some basics of graphics programming are discussed and the concepts of SDL2 surfaces and textures are introduced. Header File Defined in <SDL3/SDL_surface. I've played with a bunch of ideas, including just copying the SDL2 renderer wholesale into sdl2-compat, A pixel is drawn at (0, 0) after an SDL_RenderSetLogicalSize(renderer, 50, 50) call at the expected scale. You can set the texture scaling method by setting SDL_HINT_RENDER_SCALE_QUALITY before creating the texture. I have been looking around on many links to find out how to resize an image on SDL2, like in pygame, the "pygame. However if I change the render texture’s size times the zoom scale factor, it really starts to kill the framerate at some point. 2 to 2. See in a real game engine designed to scale, I would decouple the sprite definition (which would consist of a clip rectangle and a pointer to the sprite sheet it comes from) and the I’ve tried adding a buffer around each tile in the texture atlas, so that any bleeding simply finds the same color, but the gaps were still there. I've implemented a camera into the game, and was wondering how I would go about zooming. ); SDL_LockTexture(texture, &rect, &surface->pixels, &surface->pitch); // paint into surface pixels SDL_UnlockTexture(texture); The key UPDATED FOR C++23 | Learn to resize and scale images in your C++ SDL game using Fill, Contain, & Cover modes, similar to CSS | Clear explanations and "Irregular" texture sizes seem to work fine on Windows and Linux. For instance if I multiplied by . 5 it would scale the What would the most optimum way of changing the SDL api to allow 8bit greyscale surfaces be? I was thinking the surface’s pallete pointer == NULL, but might screw up pre-existing I recently got into SDL 2 in C++. On my 1920x1200 monitor, this app thinks it's talking to a 640x480 resolution now, but SDL is using the GPU to scale it up to use all those pixels. # SDL_GetTextureScaleMode Get the scale mode used for texture scale operations. Fastest: Example: When I create a window 3840 pixels wide, it reaches outside of the monitor (which is also 3840 pixels wide) to the next monitor. | Clear explanations and SDL 2 also has a new feature for SDL surfaces called soft stretching, which allows you to blit an image scaled to a different size. Or should I be doing transformations like scaling on every single texture that needs to be rendered. # SDL_SetTextureScaleMode Set the scale mode used for texture scale operations. h> Syntax SDL_HINT_RENDER_SCALE_QUALITY SDL_HINT_RENDER_SCALE_QUALITY In GL, you can set filter parameters like "GL_NEAREST" and "GL_LINEAR" to control the way that textures are resized when they are stretched or shrunk.

SDL Development ronkrepps January 23, 2014, 5:58pm 1 I noticed something odd when using RENDER_SCALE_QUALITY of linear or best. While this might not be the optimal scaling method 2008 not SDL2 custom blitting 2010 use SDL_gfx 2008 can't be done use SDL_gfx, 2015 use SDL_BlitScaled, 2015 use SDL_RenderCopyEx Is a custom blitter or SDL_gfx The Simple Directmedia Layer Wiki SDL_ScaleMode The scaling mode. It was previously done with pixel manipulations since it was not a costly also seen scaling the screen in some SDL demo which uses OpenGL. org > Forums > Non-*NIX Forums > Programming [SOLVED] Need SDL2 tutorial and how to I scale textures ? Programming This forum is for all programming questions. The Simple Directmedia Layer Wiki (See SDL3/SDL_CreateTexture for the SDL3 version. However, the wireframe space shuttle still seems to be Stay in the surface area and just do SDL_UpdateWindowSurface ()? Do textures by writing everything to a ‘screen’ surface and push as a texture that at the end? Cache as much as Changing Font Size There are two ways we change the font size after we set it with SDL_TTF. 2 I use rotozoom to make 2x/3x/etc zoom working without problems. I like to scale the background using linear scaling, but for NAME ¶ SDL_SetTextureScaleMode - Set the scale mode used for texture scale operations. For example, if you have a game that uses Return Value ( *) Returns the created texture or NULL on failure; call () for more information. For example, if you have Those could however be fixed using SDL_RenderSetIntegerScale. SDL_PRINTF_VARARG_FUNC (4); +/** + * Set default scale mode for new textures for given renderer. The Simple Directmedia Layer Wiki SDL_RenderGetScale Get the drawing scale for the current target. Header File Defined in SDL_render. SDL_Texture is pixel data the GPU can access. My opinion is that setting GL_TEXTURE_MAG_FILTER to GL_LINEAR looks horrible and should never be used. EDIT: I have updated the program to use textures, but the image I am just trying to scale (make bigger proportionally) my character based on windows weight and height. Load a . h> Syntax It doesn't support target textures, but they're a required feature in SDL 3. The problem is that if I resize the window, it stops updating images. 0 Rendering SDL_Texture Re: SDL 2. com/libsdl-org/SDL/blob/SDL2 By the way, it is strongly recommended to set the scaling filter (SDL_SetHint ()) to a better quality filter, because heavy scaling is done behind the scenes by SDL_RenderSetLogicalSize (). Seems to affecting all renderers and platforms. I myself use in my SDL2 game which gets upscaled while rendering custom scaling, meaning that I scale all LinuxQuestions. 0 Simple Directmedia Layer SDL3 FUNCTIONS. FUNCTION PARAMETERS ¶ texture the We'll do a static texture (upload once, draw many times) with data from a bitmap file. \param scaleMode A pointer filled in with the current scale mode. The anisotropic filter doesn’t do anything for me, even if I used Direct3D. Explanation Displays now To do this, we had to resort to converting an image surface to a pixel format we could work with, and then copy the pixels over to a texture for I'm using an SDL_Window and SDL_Renderer. 0 scale/resample textures behind the scenes? Use SDL_CreateTextureFromSurface to make it a texture, and by using SDL_RenderCopy, you can specify the exact dimensions you want your image to fill and it will scale it for you. If I scale to 50% or larger (75%, 60% etc), it looks decent. If there was a way of The Simple Directmedia Layer Wiki SDL_SetTextureScaleMode Set the scale mode used for texture scale operations. Linear How do I prevent SDL from scaling textures when resizing a window? Ask Question Asked 6 years, 10 months ago Modified 6 years, 10 months ago Explore SDL3 renderer examples and learn how to create windows, load textures, and render graphics effectively. h Syntax To scale up individual textures, you can use either SDL_SetLogicalPresentation (), which takes care of scaling each graphical element automatically, or you can scale everything Is using some combination of SDL_RenderSetScale and SDL_RenderSetViewport appropriate for global zoom? @Peter87 your solution makes sense when rendering a texture, but Off the bat, I am very much a beginner C++ and SDL, so I apologize if I’m missing something obvious here. Learn to use SDL_BlitScaled () and prevent stretching. If the scale mode is not supported, the closest supported mode is chosen. Thread Safety This function should only # SDL_GetDefaultTextureScaleMode Get default texture scale mode of the given renderer. h>](https://github. Set the scale mode used for texture scale operations. So I’m wondering what’s the best (and fastest) way to scale the screen, without making it look ugly. Contribute to libsdl-org/SDL development by creating an account on GitHub. Scaling by using Rectangles // render texture UPDATED FOR C++23 | C++ SDL2 techniques for image positioning and scaling. Since we have a fairly low-res game In this chapter some basics of graphics programming are presented and the concepts of SDL3 surfaces and SDL3 textures are introduced. \param texture The texture to update. Textures do not provide direct access to pixels Totally false! Just create a texture with access type SDL_TEXTUREACCESS_STREAMING and then call SDL_LockTexture(), which updates the user Scaling the renderer of the window Scaling the renderer of the window The texture is divided into 9 regions: 4 corners (which don’t scale), 4 edges (which scale in one direction), and a center (which scales in both). GL_NEAREST always looks better. Next, figure out the correct size and position of your game texture on your actual window, I want to do one simple thing that just seems to be impossible with SDL2 I have a texture of 632x400 (yes, weird resolution) that is basically my framebuffer, and I want to stretch this SDL2 Textures Our previous reading introduced the SDL2 library, which gives us a portable way to create windows and draw graphics from C. Contribute to TheSpydog/SDL_gpu_examples development by creating an account on GitHub. . bmp file, and then draws it, scaling it up and down. ## Header File Defined in [SDL_render. 3, and while on the SDL Wiki, I've come across SDL_Renderer, SDL_Window, and SDL_Texture. Please note, that in case of rendering to a texture - there is no need to call SDL_RenderPresent after drawing needed objects to a texture, and should not be done; you are only With Textures (from what I have understood) you have to define your target Texture with SDL_TEXTUREACCESS_TARGET, then bind it to a new SDL_Renderer (which has to When we want to render to a texture we need to set its texture access to SDL_TEXTUREACCESS_TARGET, which is why this function takes SDL Texture not scaling to the renderQuad Ask Question Asked 5 years, 4 months ago Modified 5 years, 4 months ago How can I implement a zoom feature using these scaling techniques? Stylized Scales 002 – Free seamless texture, 1024 x 1024, with the following maps: Diffuse Normal Displacement Roughness Ambient Occlusion Categories:Stylized Textures• Tags: Animal, archviz, Multiply/Divide will scale the UV coordinates which inturn will scale the SDF down or up depending on the values. h Syntax SDL uses letterboxing for the scaling, however, so it will always keep everything in view. When we deal with SDL textures you need an SDL_Renderer to SDL_RenderCopy(renderer, texture, nullptr, dest); Other possibility, you could set the renderer's logical scale to a fixed value (SDL_RenderSetLogicalSize(renderer, width, height)) In GL, you can set filter parameters like “GL_NEAREST” and “GL_LINEAR” to control the way that textures are resized when they are stretched or shrunk. While in SFML I simply see more of the game’s world the However if I change the render texture’s size times the zoom scale factor, it really starts to kill the framerate at some point. h> Syntax By using SDL_RenderCopy you can do all the zoom in/out or scaling stuff, by using non null values for the srcrect and dstrect parameters. h> Syntax Then, use SDL_SetRenderTarget () to set this texture as your render target — and make sure any other textures you’re rendering from have SDL_HINT_RENDER_SCALE_QUALITY The Simple Directmedia Layer Wiki SDL_HINT_RENDER_SCALE_QUALITY A variable controlling the scaling quality Header File Defined in SDL_hints. Next, something that one might find important, SDL_SetHint is called to set the render scale quality to nearest-pixel. How the image is loaded: SDL_Surface* I've recently started upgrading my SDL version from 1. It loads an SDL surface in a way that's similar to the way we used to in loadFromFile (), minus the texture Dear All, I have a couple of question: What’s the difference between Texture and Surface? It seems that most of the time I have to create Surface and then creating a Texture with § Parameters texture: the texture to update. Hence, textures are almost always created from surfaces, using the function Linear filter for scaling. 2 to SDL 2. However that approach requires calling SDL_CreateTextureFromSurface (), along with the SDL_FreeSurface () and SDL_DestroyTexture () Scaling, resolution and pixel art Scaling, resolution and pixel art Scaling, resolution and pixel art The Simple Directmedia Layer Wiki SDL_SetRenderScale Set the drawing scale for rendering on the current target. png file, and then draws it a few times each frame. 0 textures? Does the texture need to be specially initialized and locked down? Graphic artifacts when using RENDER_SCALE_QUALITY Graphic artifacts when using RENDER_SCALE_QUALITY Re: Graphic artifacts when using RENDER_SCALE_QUALITY I have set scaling mode to nearest neighbor with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"); and upscale sprites with passing Texture Rendering: The sdl_texture example shows how to load and render textures in your SDL3 projects. You can scale a texture bigger or smaller by setting the size of this rectangle different than const SDL_Rect* srcrect. I've tried doing many things, but +* SDL_HINT_RENDER_SCALE_QUALITY - textures now default to linear filtering, use SDL_SetTextureScaleMode(texture, SDL_SCALEMODE_NEAREST) if you want [SDL2]-Scale Display Window Based on Window Resize?

If the texture is to be scaled to, say, 123 pixels, it is impossible to have all 16 pixels of a texture scaled up to the same size. The default texture scale mode is SDL_SCALEMODE_LINEAR. If I render a rectangle as SDL_QueryTexture (img, NULL, NULL, &w, &h); // get the width and height of the texture // put the location where we want the texture to be drawn into a rectangle Hi, I’m having a little trouble with some texture. All the textures are loaded with SDL_Image and just one texture is pixelated. But anything smaller, In general, if you are using any 3D API textures you should be allowed to set te Texture filtering to "Point" (Nearest-neighbor interpolation) instead of the default Bilinear or Anisotropic wich are the After initializing SDL3 and setting up the window, renderer and texture as known, the rectangle is getting some values. \param scaleMode the what is the proper way to scale an SDL Surface? I found one explanation online but it required redrawing the Surface pixel by pixel. uk Parallel Realities games I have finally started getting used to SDL 2's basic functions for rendering and I have stumbled across a problem that I believe the public might be able to answer. OpenFont(): Re-setting the font_size using SDL gray scale image from a a color image? Ask Question Asked 12 years, 6 months ago Modified 12 years, 2 months ago SDL 2. This gist has an example, I will inline it below. 6 Render Targets 🔗 ℹ The texture is divided into 9 regions: 4 corners (which don’t scale), 4 edges (which scale in one direction), and a center (which scales in both).

Am I doing something wrong? I’m trying to render a quad with a texture. */ /* SDL_Surface is pixel data the CPU can access. The last point is that the game offer the possibility to choose a smooth display filter (Scale2x and HQ4x). I did some research and found a link at Subject: [PATCH] SDL3 removed SDL_HINT_RENDER_SCALE_QUALITY hint textures now default to linear filtering, use SDL_SetTextureScaleMode(texture, Thanks for SDL, and all the work into SDL3!! I just pulled the latest changes from main and having an issue with the texture scale mode From the short description of SDL_RenderSetScale () and SDL_RenderSetLogicalSize () on the SDL2 wiki I was under the impression that these commands # SDL_SetDefaultTextureScaleMode Set default scale mode for new textures for given renderer. + * + * When a renderer is created, scale_mode defaults to Set the scale mode used for texture scale operations. By which I mean requesting a 63x61 texture doesn't fail and it doesn't seem to silently give you a 64 x 64 either. How can I do that?

This example creates an SDL window and renderer, and uses SDL_RenderTextureAffine to draw a 3D cube using only 2D rendering operations. Was trying to scale SDL texture by modifying the destination SDL rectangle Method one that I’ve tested is to scale the texture down to a quarter the size or even less, and scaling it up with linear filtering enabled (SDL_HINT_RENDER_SCALE_QUALITY) , render: Fix setting the scale mode for non-native textures committed 12:49PM - 02 Apr 22 UTC ccawley2011 +2 -1 We would like to show you a description here but the site won’t allow us. Second, as far as I know The last argument in SDL_BlitSurface() takes a pointer to an SDL_Rect and its the argument that decides what region of the window the image So basically what I want is a way to smooth scale the image before displaying it, any help would be appreciated. transform. ) SDL_CreateTexture Create a texture for a rendering context. h](https://github. com/libsdl-org/SDL/blob I’d recommend keeping SDL_RenderSetScale and then for stuff like text using a font size scaled by the render scale, so your text textures won’t need to be stretched. h Syntax Just a note here in case changing the filter mode is important: Â With SDL_gpu, the texture scale filters are part of the per-texture GPU_Image state and can be changed any time Saw this post here about using SDL_ttf to render text in a game. You need some sort of anti How exactly can one get to the RGBA pixel arrays of SDL 2. h> Syntax Here is the background of this issue: I wanted to display a zoom window in nearest scale mode for a texture shown in linear mode.

Hi, I have two different types of textures in my game. If so, you can use SDL_SetHint by setting hint SDL_HINT_RENDER_SCALE_QUALITY Scaling textures by using SDL_RenderCopy and a smaller target Rect is giving pixelated results. This example creates an SDL window and renderer, then a streaming texture that it will update every frame before drawing it to the screen. Here is the prototype of the function : int # SDL_SetTextureScaleMode Set the scale mode used for texture scale operations. h Textures in SDL have their own data type intuitively called an SDL_Texture. Remarks The contents of a texture when first created are not defined. h> Syntax SDL_RenderTextureTiled Tile a portion of the texture to the current rendering target at subpixel precision. Is it possible to use SDL_TTF with SDL_Render/SDL_Window? If so, how?
