GL_INVALID_VALUE 框線不是 0 或 1。 GL_INVALID_OPERATION 在glBegin呼叫與 glEnd的對應呼叫之間呼叫函式。 備註 glTexImage2D函式會指定二維紋理影像。 文字繪製會將指定紋理影像的一部分對應至啟用紋理的每個圖形基本類型。 使用 glEnable 和 glDisable搭配引數GL_TEXTURE_2D啟用和停用二維文字。
因此,使用PBO方法,1282错误似乎是指纹理分辨率问题! 对于涉及PBO的错误1282 (GL_INVALID_OPERATION),OpenGL文档表示: 代码语言:javascript 复制 GL_INVALID_OPERATIONis generatedifa non-zero buffer object name is bound to theGL_PIXEL_UNPACK_BUFFERtarget and the buffer object's data store is currently mapped...
But in Safari 10.1 and Chrome 57.02 on MacBook Pro (Retina, 15-inch, Mid 2014) / Version 10.12.4 I see this behaviour. [Warning] WebGL: INVALID_OPERATION: texImage2D: ArrayBufferView not big enough for request (mapbox-gl.js, line 352) at sprite_atlas.js 241 [Warning] WebGL: INVAL...
GL_INVALID_VALUE width or height was less than zero or greater than 2 + GL_MAX_TEXTURE_SIZE, or if either could not be represented as 2k + 2(border) for some integer value of k. GL_INVALID_VALUE border was not 0 or 1. GL_INVALID_OPERATION glTexImage2D was called between a call ...
GL_INVALID_OPERATION is generated if type is GL_UNSIGNED_SHORT_4_4_4_4 or GL_UNSIGNED_SHORT_5_5_5_1 and format is not GL_RGBA. Associated Gets glGet with argument GL_MAX_TEXTURE_SIZE or GL_MAX_CUBE_MAP_TEXTURE_SIZE Examples
如果format与internalformat不匹配,或者type与format不匹配(比如type为GL_UNSIGNED_SHORT_5_6_5 但是format 不是GL_RGB,或者type 是 GL_UNSIGNED_SHORT_4_4_4_4 或者 GL_UNSIGNED_SHORT_5_5_5_1 而 format 不是 GL_RGBA),则会出现GL_INVALID_OPERATION的错误。
