【问题描述】:
我有一个使用 Delphi 7 和 VCL 开发的项目,无需任何修改即可编译和使用新的 Delphi XE7,我遇到的唯一问题是 TBitBtn 的字形图像显示错误(如您所见,颜色和位置不一样)在运行时,尽管在设计时显示良好。
设计时间:
运行时间:
什么会导致问题?
注意
使用旧的 Delphi 7 我没有这个问题:图像在设计和运行时都正确显示。
紧随 dfm 中 Glyph 数据的前 3 行:
Glyph.Data = {
36050000424D3605000000000000360400002800000010000000100000000100
080000000000000100000000000000000000000100000000000000164900001C

...
在 Delphi 7 和 Delphi XE7 中是一样的。
如果我单击 TBitBtn 的 Glyph 属性,我可以在对话框中看到图像(错误的图像),如果我用 OK 确认,IDE 会以这种方式更改 DFM 文件中的 Glyph 属性(差异输出):

this link 有完整的 DFM 文件,该文件存在问题。
【问题讨论】:
-
那是什么类型的图像?根据快速观察,似乎某些数据损坏发生在运行时或数据未正确加载。如果你看图片,似乎颜色通道可能已经被打乱了。绿色似乎被蓝色取代,蓝色被红色取代,好像颜色通道会移动一个字节。图像位置偏移也可能是这种数据损坏或数据处理不正确的结果,好像文件头没有正确解析,程序可能将其视为图像数据。
-
请将图像显示为您在 D7 中加载到 BitBtn 中的原始 .bmp。还从 .dfm(D7 和 XE7)复制
Glyph.Data = {之后的前三行十六进制值 -
我认为原始图像是PNG文件(可能转换为BMP),我不能肯定,因为我从以前的开发人员那里继承了该项目,我没有原件导入的图像文件......无论如何,我已经用一些有用的信息更新了这个问题。谢谢。
-
正如您在下面看到的,我分析了您在上面提供的新信息,但它没有任何意义。我附上了一张图片供您尝试,它对您有什么作用?顺便说一句,你在 UI 中使用 TActions 吗?
-
使用完整 DFM 文件的链接更新帖子。谢谢。
